News | New Study: Good Sleep May Support Ovarian Reserve
A recent study published in Scientific Reports found a significant association between sleep problems and diminished ovarian reserve (DOR). Conducted by a team from the Reproductive Medicine Center at Fujian Maternity and Child Health Hospital, affiliated with Fujian Medical University, the study analyzed sleep measures and ovarian function among women receiving infertility treatment. It proposed that sleep disorders may increase the risk of diminished ovarian function by affecting hormone levels and follicular development.
Ovarian Reserve and the Challenge of Infertility
Ovarian reserve is an important measure of female fertility. Clinicians commonly assess ovarian function with hormone tests, such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-Müllerian hormone (AMH), as well as ultrasound measures such as antral follicle count (AFC). As industrialization, environmental pollution, and social pressures increase, infertility is becoming more common among younger women, and diminished ovarian reserve is a major challenge in assisted reproductive technology (ART).
Although the mechanisms underlying diminished ovarian reserve are not fully understood, the research team believes sleep disturbance may be an overlooked factor.
Study Methods
The study collected data from 979 women who underwent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) at Fujian Maternity and Child Health Hospital between July 2020 and June 2021. Participants were divided into DOR and non-DOR groups. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), obstructive sleep apnea risk with the STOP-Bang questionnaire, and daytime sleepiness with the Epworth Sleepiness Scale (ESS).
The researchers also classified ovarian reserve using strict hormone-level and follicle-count criteria and used statistical analyses to examine associations between sleep measures and DOR.
Study Results
The DOR group had a significantly shorter average sleep latency than the non-DOR group (15 versus 22 minutes, p=0.001) and a shorter total sleep duration (7.35 versus 7.57 hours, p=0.014). Sleep latency and duration differed significantly on the PSQI, while daytime sleepiness and obstructive sleep apnea scores did not.
Further analysis found:
Sleep duration and hormone levels: women who slept more than 8 hours had significantly higher AMH levels and antral follicle counts than women who slept fewer than 6 hours (p=0.007, 0.005, 0.030).
Sleep latency and ovarian reserve: women with a sleep latency of 30-44 minutes had significantly higher AMH levels than other groups (p=0.001, 0.011, 0.036).
Among women aged 35 or older, snoring and shorter sleep latency were identified as independent risk factors for DOR (OR=2.489, 2.007; p=0.040, 0.008). Among women with a body mass index (BMI) below 25 kg/m², age and sleep latency were also significant risk factors (OR=0.828, 1.761; p<0.001, 0.003).
Significance of the Study
The findings suggest that shorter sleep latency and snoring may significantly increase the risk of diminished ovarian function by disrupting hormone secretion and follicular development, particularly among women over 35. The team recommends including sleep quality as an important consideration in infertility evaluations to help optimize reproductive treatment outcomes.
