Merino PM, et al. - Ovarian function between adolescents conceived using assisted reproductive technology (AcART) and adolescents who were conceived spontaneously (AcSP) were compared in this multicenter study. Researchers assessed differences in ovulation, reproductive hormones, and ovarian morphology among 22 AcART and 53 AcSP at 1-2 years after menarche. Compared to AcSP, AcART had later menarche, lower ovulation rates, and higher luteinizing hormone levels. AcART and AcSP had similar incidence of oligomenorrhea and the cycle length and had similar levels of anti-Müllerian hormone, inhibin B, follicle-stimulating hormone, estradiol, and androgens.
