Can Poor Sleep or Insomnia Make It Harder to Get Pregnant?
Last updated: September 17, 2026. Medically reviewed by Dr. Avinesh Bhar, Board-Certified Sleep Physician, SLIIIP.com.
Yes, research links chronic poor sleep and insomnia to a longer time to conception, though sleep is usually one factor among several rather than the sole cause of fertility difficulty. Dr. Avinesh Bhar, a Board-Certified Sleep Physician at SLIIIP.com, points out that couples trying to conceive often address diet, stress, and timing while overlooking an undiagnosed sleep disorder that is quietly affecting hormone regulation. The brain region that controls your sleep-wake cycle also regulates the release of reproductive hormones, which is why disrupted sleep and disrupted fertility hormones are so closely linked. This is different from insomnia that develops during an existing pregnancy, which is a separate topic.

How Sleep and Reproductive Hormones Are Connected
The hypothalamus, a small structure at the base of the brain, governs both your sleep-wake cycle and the release of key reproductive hormones like luteinizing hormone and follicle-stimulating hormone. When sleep is chronically disrupted, this shared control center can throw off the timing and levels of hormones needed for regular ovulation. This is a plausible biological mechanism, though researchers note that the exact degree of impact varies between individuals.
Can Insomnia Make It Harder to Get Pregnant?
Yes, several studies point in this direction. A review of sleep and reproductive health found that women with diagnosed sleep disorders had a substantially higher rate of self-reported infertility compared with women without a sleep disorder. Short sleep duration and poor subjective sleep quality have also been associated with longer time to conception in multiple studies, though findings are not fully consistent across every study design.
Sleep Apnea and Fertility: An Often Missed Connection
Obstructive sleep apnea is associated with hormonal disruption that can affect ovulation, and it is significantly underdiagnosed in women, particularly those with polycystic ovary syndrome. Women with PCOS have a notably higher rate of sleep-disordered breathing than women with unexplained infertility, independent of body weight, which makes sleep apnea a reasonable factor to rule out during a fertility workup rather than an afterthought.
What You Can Actually Do While Trying to Conceive
Improving sleep will not replace a fertility workup, but it addresses one modifiable factor while other evaluations are underway. Consistent, adequate sleep supports the same hormonal rhythms that regulate ovulation, so treating an underlying sleep disorder is a reasonable parallel step, not a substitute for medical fertility care.
- Keep a consistent sleep and wake schedule, since irregular timing disrupts the same hormonal rhythms involved in ovulation.
- Aim for 7 to 9 hours of sleep, since both very short and very long sleep durations have been associated with reduced fertility in research.
- Mention any snoring, gasping, or unrefreshing sleep to your fertility specialist directly, since these are not standard fertility workup questions everywhere.
- Limit alcohol and late caffeine while trying to conceive, since both can fragment sleep quality.
- Track your sleep alongside your cycle for a few months, since patterns can reveal whether poor sleep clusters around certain cycle phases.
How This Differs from Insomnia During Pregnancy
This article covers sleep and the ability to conceive. Insomnia that develops after pregnancy begins is a separate, well documented pattern with its own causes and trimester-specific changes. For that topic, see our article on insomnia and pregnancy, and for a look at how PCOS relates to sleep-disordered breathing specifically, see sleep apnea in women.

When to See a Doctor
If you are trying to conceive and sleep has felt consistently poor for more than a few weeks, it is reasonable to raise this with your care team early rather than waiting. Dr. Bhar recommends a sleep evaluation for anyone trying to conceive who snores, wakes up gasping, feels excessively tired despite adequate time in bed, or has been told they may have PCOS, since sleep apnea is common and treatable in this group. A home sleep test can often answer this question without adding significant time or complexity to an already busy fertility evaluation.

Frequently Asked Questions
Can poor sleep really affect fertility?
Research links chronic poor sleep and short sleep duration to a longer time to conception, likely through effects on reproductive hormone regulation.
Can insomnia specifically make it harder to get pregnant?
Studies have found higher self-reported infertility rates among women with diagnosed sleep disorders, including insomnia, compared with those without.
How does sleep affect fertility hormones?
The brain region that controls sleep-wake timing also regulates hormones needed for ovulation, so disrupted sleep can disrupt that hormonal rhythm.
Does sleep apnea affect fertility in women?
Yes, sleep apnea is associated with hormonal disruption relevant to ovulation and is notably underdiagnosed in women trying to conceive.
Is the fertility and sleep connection stronger with PCOS?
Yes, women with PCOS show a significantly higher rate of sleep-disordered breathing than women with unexplained infertility.
How much sleep is considered ideal while trying to conceive?
Most research points to 7 to 9 hours as the range associated with the best fertility outcomes, with both shorter and longer sleep linked to reduced fertility in some studies.
Can fixing my sleep alone help me get pregnant?
Improving sleep addresses one modifiable factor, but it should complement, not replace, a full fertility evaluation.
Should I mention snoring to my fertility doctor?
Yes, snoring, gasping, or unrefreshing sleep are worth mentioning directly, since they are not always part of a standard fertility questionnaire.
Can a home sleep test be done while undergoing fertility treatment?
Yes, a home sleep test is a simple, low-burden way to check for sleep apnea alongside ongoing fertility care.
Does IVF success depend on sleep quality?
Some studies suggest sleep quality and duration may relate to IVF outcomes such as oocyte quality and pregnancy rates, though results are not fully consistent.
Can shift work affect fertility through sleep disruption?
Yes, irregular schedules that disrupt circadian rhythm have been associated with reduced fertility in some research.
Is this the same as insomnia during pregnancy?
No, this article covers sleep and the ability to conceive, while insomnia during pregnancy is a separate, later-stage pattern.
Can stress about fertility itself cause insomnia?
Yes, the emotional stress of trying to conceive can independently disrupt sleep, creating a cycle worth addressing directly.
Does age change how sleep affects fertility?
Sleep’s hormonal effects apply across reproductive ages, though overall fertility naturally declines with age regardless of sleep quality.
Can melatonin supplements help fertility?
Melatonin has antioxidant properties studied in relation to egg quality, but supplement use should be discussed with a fertility specialist first.
Is it worth tracking sleep alongside my menstrual cycle?
Yes, tracking both together for a few months can reveal patterns that are useful to share with your care team.
Can undiagnosed sleep apnea be mistaken for infertility stress?
Yes, fatigue and mood changes from untreated sleep apnea can be mistaken for general stress rather than a treatable breathing disorder.
Does this connection apply to male fertility too?
Research on male fertility and sleep is more limited but suggests similar hormonal and circadian pathways may be involved.
Can poor sleep affect fertility treatment outcomes even if conception happens?
Some studies have looked at sleep quality in relation to pregnancy outcomes after fertility treatment, though this remains an active area of research.
What is the first step if I am concerned sleep is affecting my fertility?
Mention your sleep symptoms to your fertility specialist and consider a sleep evaluation, especially if you snore, feel excessively tired, or have PCOS.
