Effects of Dehydroepiandrosterone on In Vitro Fertilization Among Women Aging Over 35 Years and Normal Ovarian Reserve

Abstract

Objective: The fertility potential of women declines with aging and the likelihood of infertility and stillbirth increase. Treatment protocols involving dehydroepiandrosterone (DHEA) provide pathways on improving fertility and live birth rate. This randomized clinical trial aimed to evaluate the effect of DHEA on In Vitro Fertilization (IVF) outcomes in women over 35 years and normal ovarian reserve. Materials and methods: One hundred and six consecutive women with advanced reproductive age undergoing IVF due to infertility were enrolled in the study. Participants in the intervention group received 75 mg/day of DHEA orally 8 weeks before starting the cycle of ovulation induction. Participants in placebo group received placebo tablets during the same period. After 8 weeks, routine procedure of IVF was initiated then Clinical pregnancy, Miscarriage, Endometrial thickness and Duration of stimulation were evaluated for all the participants in both groups. Results: There is no significant difference between groups in terms of age and BMI. Mean endometrial thickness was significantly lower in DHEA group (9.63 ± 0.70vs.8.05 ± 0.70; p < 0.001) while Duration of stimulation was higher (8.98 ± 1.29vs.10.59 ± 1.43; p < 0.001). There was no significant difference between pregnancy rate, and miscarriage rate of the groups. Conclusion: According to the result of this study, DHEA supplementation may improve IVF outcomes in infertile women. Although additional larger and placebo-controlled studies using different DHEA protocols are required to support our present findings.
