Does Coronavirus Disease-19 Infection Affect Ovarian Reserve in Infertile Women? A Retrospective Study

BACKGROUND: Previous studies have revealed menstrual changes following coronavirus disease-19 (COVID-19) disease. The potential impact of COVID-19 on female reproductive organs, ovary in particular, has not been investigated thoroughly. AIMS: The aim of this study was to evaluate changes in serum levels of follicle-stimulating hormone (FSH), luteinising hormone (LH) and oestradiol (E2) following COVID-19 disease as a surrogate for the detection of ovarian vulnerability to SARS-CoV-2 infection. SETTINGS AND DESIGN: In this retrospective study, hospital records of unexplained infertile women between 21 and 40 years old who have attended our institution's reproductive medicine unit for evaluation and/or treatment of infertility have been evaluated. MATERIALS AND METHODS: Menstrual cycle day 2–5 serum follicle-stimulating hormone, luteinising hormone and E2 levels of 28 infertile women have been studied both before and after the COVID-19 disease to evaluate ovarian reserve before the ovulation induction treatment cycle. STATISTICAL ANALYSIS USED: The demographic characteristics and hormonal results of these 28 unexplained infertile women have been compared. The Shapiro–Wilk test has been used to evaluate the normal distribution of variables. Comparison of ovarian reserve markers which were established before and after COVID-19 infection has been performed using paired samples t-test. RESULTS: All patients except one have shown mild COVID-19 symptoms and their infection courses have resulted in uneventful recovery. Serum FSH, LH and E2 levels of 24 (85%) and serum anti-Müllerian hormone (AMH) levels of 4 (15%) patients have been evaluated before and after COVID-19 disease is statistically similar. CONCLUSION: COVID-19 disease or inflammatory response of the infection itself does not seem to affect pituitary gonadotropins and ovarian hormones in infertile women based on menstrual cycle day 2–5 serum FSH, LH, E2 and AMH levels. Further studies including higher patient numbers are urgently needed to clarify the potential effects of COVID-19 disease on the gonadal function of women.
