    Sains Malaysiana, 2004;33.
    Effect of Centella asiatica aqueous leaf extract was assessed on spermatogenesis and sperm quality in mice. The experiment was conducted by giving three different doses of C. asiatica extract orally; 25mg/kg, 50mg/ kg and 100mg/kg body weight daily for four weeks respectively. Control group was treated with normal saline (0.9% NaCl). Marked decreases in sperm count and motility were found in sperm collected from the cauda epididymis of treated mice. The treatment, however did not affect sperm mortality and morphology. Histologically, signs of inhibition of testicular cells appeared clearly at dose 100mg/kg, when the lumen of seminiferous tubules were only full with spermatocytes and spermatids. The present results show that the plant has antispermatogenic effect in mice. It is therefore, suggested that leaf extracts of C. asiatica possess antifertility activity in male mice.
    Kesan ekstrak berakua daun Centella asiatica telah dikaji ke atas proses spermatogenesis dan kualiti sperma mencit. Kajian dijalankan dengan memberikan tiga dos C. asiatica secara oral masing-masing; 25mg/kg, 50mg/ kg and 100mg/kg berat tubuh mencit setiap hari selama empat minggu. Kumpulan kawalan diberikan larutan salin normal (0.9% NaCl). Pengurangan dalam bilangan dan motiliti sperma yang ketara telah diperhatikan pada semua kumpulan mencit yang diberikan ekstrak C. asiatica. Walau bagaimanapun pemberian ekstrak C. asiatica tidak mendatangkan kesan terhadap mortaliti dan morfologi sperma. Kajian histologi pula menunjukkan terdapat kesan perencatan sel-sel spermatogenik testis pada dos C. asiatica 100mg/kg di mana lumen pada tubul seminiferus hanya dipenuhi dengan sel-sel spermatosit dan spermatid. Hasil kajian menunjukkan tumbuhan ini mempunyai kesan antispermatogenik pada mencit. Oleh itu dicadangkan bahawa ekstrak daun C. asiatica mempunyai aktiviti antikesuburan pada mencit jantan.

    Baicalein (BC), a flavonoid, which lacks the qualities of reproductive health and shows adverse effects, is tested in this study. Inseminated mice were injected with 30, 60, and 90 mg BC/Kg body weight on gestation days 11, 13, 15, and 17. The F1 BC-exposed males of each dosage were divided into six groups. First three groups (n = 6 from each BC dosage) were used for assessment of reproductive performance, the others (n = 4 from each BC dosage) were administered with testosterone 4.16 mg/kg body weight on postnatal days 21, 31, and 41. The reproductive health of adult F1 males at the age of 55 and 60 was tested. Prenatal BC exposure showed reduced fertility after cohabitation with control females. The BC exposure significantly reduced the body weight, tissue indices, and sperm parameters (motility, count, viability, and daily sperm count) and altered the sperm membrane in a hypoosmotic swelling test. A downward trend was observed in testicular steroidogenic marker enzymes (3β- and 17β-steroid dehydrogenases) and serum testosterone, whereas increase in serum titers of FSH and LH along with altered the testicular histology. Conversely, testosterone (4.16 mg/kg body weight) partially recovered reduced male reproductive health by BC. BC impaired male reproductive health due to low levels of testosterone is reverted by external testosterone is evidenced in this study.

    Introduction. This study aims to evaluate the effectiveness of Tualang honey on sperm parameters, erectile function, and hormonal and safety profiles. Methodology. A randomized control trial was done using Tualang honey (20 grams) and Tribestan (750 mg) over a period of 12 weeks. Sperm parameters including sperm concentration, motility, and morphology were analyzed and erectile function was assessed using IIEF-5 questionnaire. Hormonal profiles of testosterone, FSH, and LH were studied. The volunteers were randomized into two groups and the outcomes were analyzed using SPSS version 18. Results. A total of 66 participants were involved. A significant increment of mean sperm concentration (P < 0.001), motility (P = 0.015) and morphology (P = 0.008) was seen in Tualang honey group. In Tribestan group, a significant increment of mean sperm concentration (P = 0.007), and morphology (P = 0.009) was seen. No significant differences of sperm concentration, motility, and morphology were seen between Tualang honey and Tribestan group and similar results were also seen in erectile function and hormonal profile. All safety profiles were normal and no adverse event was reported. Conclusion. Tualang honey effect among oligospermic males was comparable with Tribestan in improving sperm concentration, motility, and morphology. The usage of Tualang honey was also safe with no reported adverse event.

    PMID: 23365499 MyJurnal
    The antimetabolite, 5-fluorouracil is widely used in the treatment of cancers. Although its toxic effects on testis causing germinal epithelial sloughing, tubular atrophy and generation of multinucleated cells were reported, its effect on spermatogenesis has not been studied. Hence the present study was conducted to evaluate the effects of 5-fluorouracil on epididymal sperm count. Male Wistar rats were employed in the study (n=5 per group). The animals were injected (i.p) with five consecutive doses of 5-fluorouracil (10, 20, 30mg/kg b.w) at an interval of 24h and the control with 0.1ml-distilled water. Samples were obtained at 14, 35, 42 and 70 days after injection. Rats were sacrificed, a laparatomy was performed and epididymes were collected in 1ml phosphate buffered saline (pH 7.2), minced, filtered and stained with 1% aqueous eosin Y. An aliquot was taken in leucocyte pipette, diluted with phosphate buffered saline and sperm count was done as per the standard procedure. Data were analyzed by Mann Whitney U test. The results of this study revealed that 5 - fluorouracil significantly decreased the sperm count in a dose- and time-dependent manner.

    Razak RNHA, Ismail F, Isa MLM, Wahab AYA, Muhammad H, Ramli R, et al.
    Malays J Med Sci, 2019 Jan;26(1):44-57.
    PMID: 30914892 MyJurnal DOI: 10.21315/mjms2019.26.1.4
    Background: Cyclophosphamide (CP) is a widely used anti-neoplastic and immunosuppressive agent that is associated with adverse side effects including reproductive toxicity. Aquilaria malaccensis (AM) is a traditional medicinal plant which was reported to exhibit high anti-oxidant and free radical scavenging properties. The present study was aimed to evaluate the protective effects of AM leaves extract on sperm quality following toxic exposure to CP.

    Methods: Forty-eight male Sprague Dawley rats were allocated into eight groups of six rats (n = 6): control, CP only (200 mg kg-1), AM only (100 mg kg-1, 300 mg kg-1 and 500 mg kg-1) and CP + AM (100 mg kg-1, 300 mg kg-1 and 500 mg kg-1). Animals were sacrificed after 63 days of treatment and the sperm from the caudal epididymis was taken for sperm analysis.

    Results: The body and the reproductive organs weight, sperm count and motility did not differ between CP and other groups (P > 0.05). A significant increase (P < 0.05) in percentage of the dead and abnormal sperm were seen in the CP alone treated group compared to the control group. Co-administration of AM to the CP exposed rats significantly reduced the (P < 0.05) percentage of abnormal sperm as compared to the CP only group.

    Conclusion: Overall, the present results represent the potential of AM to protect against CP induced reproductive toxicity.

    Memon AA, Wahid H, Rosnina Y, Goh YM, Ebrahimi M, Nadia FM, et al.
    Anim. Reprod. Sci., 2011 Nov;129(1-2):44-9.
    PMID: 22024366 DOI: 10.1016/j.anireprosci.2011.10.004
    The aim of this study was to determine the effect of butylated hydroxytoluene (BHT), a lipid-soluble anti-oxidant added in different concentrations to the Tris egg yolk extenders on semen cytological parameters pre freezing and post thawing (motility, morphology, viability, acrosome integrity and membrane integrity) of Boer goat spermatozoa. A total of 40 ejaculates from four Boer goat bucks were collected using an artificial vagina. Ten replicates of the ejaculates were diluted with a Tris egg yolk based extender which contained various concentrations (0.5mM, 1.0mM, 2.0mM and 3.0mM) of butylated hydroxytoluene while one sample was processed without supplementation of antioxidant and served as control. The diluted semen was cooled at 4°C and loaded into the straw and then stored in liquid nitrogen. It was evident that supplementation of BHT produces positive effect in terms of motility, membrane integrity and acrosome integrity in comparison with the control group in cooled and frozen Boer goat semen. Results showed significant differences in motility, membrane integrity, acrosome integrity and viability of cooled and frozen Boer goat spermatozoa at different concentrations. Motility, membrane integrity, acrosome integrity and viability was significantly higher in all treated groups than the control group (P<0.05) while there was no significant differences (P>0.05) in morphology trait between all group in cooled semen. However, improvement (P<0.05) was observed only in terms of the membrane integrity and acrosome integrity compared to the control and other treated groups in frozen semen. In conclusion, BHT can be used in cryopreservation of Boer goat semen in order to reduce the oxidative stress on spermatozoa.

    PMID: 10982126
    Thirteen sexually mature captive male lesser Malay chevrotains (Tragulus javanicus) were each anesthetized twice with tiletamine-zolazepam for electroejaculation. Viable spermatozoa were collected from all animals. The semen was creamy, milky, pale yellowish, or watery. The mean values for ejaculate volume, sperm concentration, and percentages of sperm motility, normality and viability were 23.7 +/- 2.5 microl, 366.9 +/- 127.8 x 10(6) spermatozoa/ml, 40.0% +/- 3.1%, 71.4% +/- 1.6%, and 59.6% +/- 2.1%, respectively. Semen pH was 7-8. No adverse effects of electroejaculation were noted. These are the first reported values for semen of lesser Malay chevrotain. Electroejaculation should be usable for routine semen collection in this species.

    PMID: 12279893
    PIP:
    The efficacy of a recently marketed posttesticular male oral contraceptive, Contrasperm, was assessed in a clinical trial involving 32 Malaysian volunteers ages 21-39 years. Contrasperm is claimed to be a pure botanical extract free of toxic chemicals, steroids, and hormones. The drug is believed to cause cells surrounding the sperm in the seminiferous tubules to secrete carbon dioxide, producing a weakly acidic environment that greatly increases the sperms' metabolism and reduces the pH of semen from its normal level of 7.5 to 1.5. The manufacturer claims that this drop in pH decreases motility from 95% to 0%. Semen samples were collected by masturbation from subjects to provide baseline data. 3 days after the initial sperm analysis, subjects were given 1 capsule of Contrasperm containing 10 mcg of the active ingredient. Additional semen analyses were conducted 30 minutes, 6 hours, and 24 hours after ingestion. Sperm count and sperm motility were greatly reduced in most subjects 30 minutes after ingestion. However, 6 subjects had increased sperm counts and 4 subjects demonstrated increased sperm motility, indicating an enhancing effect. At 6 hours after ingestion, 20 subjects had lowered sperm motility and 12 subjects showed normal sperm motility, contradicting the manufacturer's claim that motility is reduced to 0%. Although Contrasperm is claimed to be effective for 6-8 hours after ingestion, its effect wore off in less than 6 hours in 37% of subjects. Both sperm count and sperm motility returned to normal levels 24 hours after ingestion, confirming the reversibility of this drug. Most subjects reported mild side effects such as muscle weakness, blurred vision, dizziness, perspiration, urgency, abnormal muscle tension, and dry throat which persisted longer than 24 hours. Further studies, with proper controls, are needed to assess the reliability and toxicity of this preparation.

    The current data report describes the predictive identification of phytochemical constituents in the bioactive extract of Ipomoea mauritiana (IM) whole plant. For several formulations this plant was commonly used as 'Vidari' for Ayurvedic medicine. Traditionally, IM tubers are used to alleviate spinal cord pain, improve breast milk, as a tonic, increase sperm count and treating jaundice. The methanol extract can potentially scavenge free radicals and possess antibacterial activity that could be correlated with its chemical composition. So it is crucial to identify the major compounds of IM. An ultra-performance liquid chromatography coupled electrospray ionization quadrupole time-of-flight mass spectrometry (UPLC-ESI-QTOF/MS) method was adopted to detect the flavonoids, saponins, alkaloids, terpenoids in IM methanol extract. Data presented here is related to a published work Antioxidant and antibacterial activity of Ipomoea mauritiana Jacq.: A traditionally used medicinal plant in Bangladesh (Alam et al., 2020). Secondary metabolites were analyzed by the comparison of the mass fragmentation arrangements with Waters UNIFI library that enables for positive identification of the compounds based on the spectral match.

    Front Vet Sci, 2021;8:658573.
    PMID: 33778042 DOI: 10.3389/fvets.2021.658573
    The binturong is a medium size carnivore belonging to the Viverrid family that lives in dense forests of South-East Asia. In addition to the protection of this vulnerable species in its natural habitat (in situ), conservation breeding efforts (ex situ) aim at maintaining a good genetic diversity while increasing the number of individuals to reinforce wild populations. Both approaches require a solid understanding of binturong's basic biology. However, there is still a lack of precise information about reproduction. The objective of this brief research report was to analyze testicular sizes and semen characteristics at different times of the year to better understand the reproductive physiology and inform future conservation efforts. A secondary objective was to describe sperm cryotolerance for the first time in that species. Examinations of testes and semen collections were conducted on two adult males. While testicular measurements were relatively constant across multiple examinations, semen characteristics (volume, viability, sperm concentrations, sperm motility) varied between samples. However, incidence of sperm morphological abnormalities was consistently high. Sperm cryotolerance appeared to be poor but further studies are warranted. The present dataset will be useful for future research on binturong reproduction and for the development of assisted reproductive techniques and biobanking of germplasms in that species.

    PMID: 31052207 DOI: 10.3390/molecules24091689
    Intracellular polysulfide could regulate the redox balance via its anti-oxidant activity. However, the existence of polysulfide in biological fluids still remains unknown. Recently, we developed a quantitative analytical method for polysulfide and discovered that polysulfide exists in plasma and responds to oxidative stress. In this study, we confirmed the presence of polysulfide in other biological fluids, such as semen and nasal discharge. The levels of polysulfide in these biological fluids from healthy volunteers (n = 9) with identical characteristics were compared. Additionally, the circadian rhythm of plasma polysulfide was also investigated. The polysulfide levels detected from nasal discharge and seminal fluid were approximately 400 and 600 μM, respectively. No correlation could be found between plasma polysulfide and the polysulfide levels of tear, saliva, and nasal discharge. On the other hand, seminal polysulfide was positively correlated with plasma polysulfide, and almost all polysulfide contained in semen was found in seminal fluid. Intriguingly, saliva and seminal polysulfide strongly correlated with salivary amylase and sperm activities, respectively. These results provide a foundation for scientific breakthroughs in various research areas like infertility and the digestive system process.

    PMID: 26623302
    The Malayan gaur (Bos gaurus hubbacki) or Seladang is classified as vulnerable by the International Union for Conservation of Nature and Natural Resources (IUCN). The Malayan gaur is mainly distributed in the tropical woodlands of Peninsular Malaysia and Southern Thailand. The aim of this study was to collect, analyze and cryopreserve the semen of wild Malayan gaur. Transrectal massage (TM) and electroejaculation (EEJ) technique was applied in semen collection of the Malayan gaur. The semen was then cryopreserved in liquid nitrogen using slow freezing technique. Makler counting chamber was used to evaluate sperm concentration and motility, while the sperm viability and morphology of fresh and post-thaw sperm was determined using eosin-nigrosin staining protocol. As a result, we have successfully collected the Malayan gaur semen using EEJ technique. Sperm motility, viability and morphological changes of the post-thaw semen of Malayan gaur were found undesirable due to the complication of the cryopreservation process. On the basis of current study it can be concluded that Malayan gaur bulls semen can be obtain by EEJ with no evidence of rectal trauma. Optimization of the process of cryopreservation for Malayan gaur sperm is needed to maintain the cryoviability of the good sperm quality. The data generated in this study would be useful in conservation of genetic diversity program for Malayan gaur.

    PMID: 32580372 DOI: 10.3390/ani10061072
    A better understanding of semen characteristics and resilience to freezing temperatures is necessary before developing assisted reproductive techniques and systematic biobanking for the Sunda clouded leopard. The objective of this study was to evaluate for the first time the semen and sperm quality (in fresh and frozen samples) of two captive Sunda clouded leopards in Malaysia. A total of 17 examinations of the reproductive tract (using ultrasonography) and electro-ejaculations were performed on the two leopards over a 2-year period. Samples obtained from Leopard 1 (8 years old) varied in terms of volume (402 ± 92 µL), pH (7.9 ± 0.9), sperm motility (54.5 ± 24.2%), sperm concentration (122.4 ± 84.7 × 106 sperm/mL), normal morphology (23.9 ± 12.3%), and viability (55.2 ± 18.2%). Midpiece defects represented the most common structural abnormality followed by abnormal tail and head defects. Samples from Leopard 2 (11 year old with abnormal testicular tissue) were of lesser quality. Two frozen semen samples from Leopard 1 were thawed and examined for acrosome integrity. Post-thawed samples contained <10% of motile spermatozoa but almost 50% of abnormal acrosomes. The present results emphasized the high incidence of structurally-abnormal spermatozoa, similar to the mainland clouded leopard. Post-thaw evaluations showed that the few surviving spermatozoa could potentially be used for in vitro fertilization or sperm injection. However, more individuals must be studied to validate those first findings that are exciting but still preliminary.

    PMID: 33986667 DOI: 10.3389/fphar.2021.631402
    Edible bird's nest (EBN) is reported to have a positive in vitro proliferative effect and contain male reproductive hormones. Spermatogonia cells proliferate during spermatogenesis under male reproductive hormones stimulation that include testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Characterization of EBN through liquid chromatography-mass spectrometry (LCMS) has found testosterone as a base peak. Six types of amino acids, estradiol and sialic acid were among the major peaks that have been characterized. Based on the presence of these reproductive components, this study evaluated different doses of EBN on sperm parameters and male reproductive hormones of Sprague Dawley rats. Sixteen Sprague Dawley rats at the age of eight weeks were randomly and equally divided into four groups, which are Control, 10 mg/kg BW/d 50 mg/kg BW/d, and 250 mg/kg BW/d EBN group. The rats were fed with EBN enriched pellet daily and water ad-libitum. Rats were sacrificed and the organ was weighed for organ coefficients after eight weeks of treatment. Sperm concentration, percentage of sperm motility, and sperm viability were evaluated. Meanwhile, ELISA method was used to measure testosterone, FSH, and LH. Findings showed that there were no significant differences in organ coefficient between groups. Supplementation of 250 mg/kg BW/d EBN demonstrated a significant increase in sperm concentration, percentage of sperm motility as well as FSH and LH level compared to 10 mg/kg BW/d group. There was a dose-dependent increase in testosterone level but was not significant between groups. Based on these findings, EBN is concluded to have crucial effects on male reproductive parameters.

    Male infertility has a complex etiopathology, which mostly remains elusive. Although research has claimed that oxidative stress (OS) is the most likely underlying mechanism of idiopathic male infertility, the specific treatment of OS-mediated male infertility requires further investigation. Coenzyme Q10 (CoQ10), a vitamin-like substance, has been found in measurable levels in human semen. It exhibits essential metabolic and antioxidant functions, as well as playing a vital role in mitochondrial bioenergetics. Thus, CoQ10 may be a key player in the maintenance of biological redox balance. CoQ10 concentrations in seminal plasma directly correlate with semen parameters, especially sperm count and sperm motility. Seminal CoQ10 concentrations have been shown to be altered in various male infertility states, such as varicocele, asthenozoospermia, and medical or surgical regimens used to treat male infertility. These observations imply that CoQ10 plays an important physiological role in the maintenance and amelioration of semen quality. The present article thereby aimed to review the possible mechanisms through which CoQ10 plays a role in the regulation of male reproductive function, and to concisely discuss its efficacy as an ameliorative agent in restoring semen parameters in male infertility, as well as its impact on OS markers, sperm DNA fragmentation, pregnancy, and assisted reproductive technology outcomes.

    L-arginine is an amino acid, which serves as the sole substrate for nitric oxide (NO) synthesis with the concomitant formation of L-citrulline in biologic system. NO has been demonstrated to be involved in smooth muscle relaxation and vasodilation, immune regulation and neurotransmission. It also has an important function as both intercellular and intracellular signals in many physiological systems, including the reproductive system where NO mediates penis erection. This study was undertaken to determine the effects of L-arginine on sperm motility, sperm count, and the nitric oxide level in the seminal plasma. Twelve sexually matured male rabbits (Oryctolagus cuniculus) were randomly divided into four groups with three rabbits each, which were control, low, medium, and high concentration groups. The treatment groups were force-fed with 100mg/kg, 200mg/kg, and 300mg/kg body weight of L-arginine for four weeks, whereas the control group was force-fed with water. Semen samples were collected every three days alternatively for a week before starting treatment and then after four weeks of treatment. Pre-treatment and post-treatment results were compared. Semen samples were collected using artificial vaginas from each group for sperm analysis such as sperm motility, sperm count and NO level in seminal plasma. Sperm motility and sperm count were analysed manually under microscope (twenty power objective), using a Makler counting chamber. NO levels in the seminal plasma were determined using Griess reaction. The results obtained from this study showed that oral consumption of L-arginine exerted a significant (p
