INTRODUCTION: Micronutrients influence female fertility, thus adequate levels are important for oocyte quality, maturation, fertilisation and implantation. This study prospectively evaluated the impact of oral multinutrient supplementation on fertility outcomes in In vitro fertilisation or Intracytoplasmic sperm injection (IVF/ICSI).
MATERIALS AND METHODS: This was a pilot study of N=50 women, who were planning for IVF treatment in University Malaya Medical Centre, Kuala Lumpur, Malaysia from July to December 2023. Women without prior nutritional treatment were consented and assigned to either the multinutrient supplementation (Omega 3, coenzyme Q10, folic acid, selenium, vitamin E, catechins) as the study group or 5mg folic acid daily as control group for at least a month prior to their IVF treatment. All women were treated using an antagonist protocol and ovarian stimulation was started with 200 -300IU of urinary HMG and or recombinant FSH. Antagonists (Ganirelix) commenced when the leading follicle reached a diameter of 11 mm. Triggering with hCG or GnRH agonist when at least 3 follicles of 17 mm in diameter were achieved. Oocyte retrieval was performed 36th hour after trigger. Conventional IVF/ICSI was used for fertilisation. All parameters recorded and analysed using SPSS.
RESULTS: The mean age (36.44 ± 3.33 vs 35.32 ± 3.47 years) and body mass index (25.28 ± 4.12 vs 24.80 ± 4.36 kg/m2) of women in multinutrient supplementation group was similar to control group. The Follicular Output Rate (FORT) in women on multinutrient supplementation showed a trend towards benefit compared to control group, although it is not statistically significant (68.12 ± 19.47 vs 64.91 ± 20.06, p=0.493). The mean number of MII oocytes retrieved from mature follicles and number of good quality embryo on day 3 after fertilisation were not statistically significant between the two groups (6.65 ±3.84 vs 6.09 ± 3.01, p=0.626 and 4.00 ± 3.10 vs 3.45 ± 2.30, p=0.549, respectively). In addition, there were no differences in endometrial thickness before embryo transfer in both groups (10.35 ± 1.32mm vs 10.36 ± 2.04mm, p=0.320). However, the total dose of follicle stimulating hormone and duration of controlled ovarian stimulation were lower in the study group compared to control group (2410 ± 656.82 IU vs 2706.82 ± 536.15 IU, p= 0.119 and 8.90 ± 2.13 days vs 9.68 ± 1.29 days, p=0.164, respectively).
CONCLUSION: A multinutrient supplementation given for a minimum of 28 days, may have a positive effect on FORT and lower use of gonadotropin. More and larger sample research is warranted to prove this effect.
