Sleep does not merely mean you feel refreshed, but it has an enormous effect on your body and especially your hormones, which are essential to fertility. Your screwed up sleep schedule or bad quality sleep is likely silently disrupting your hormones and hindering your efforts to conceive.
Let us make this clear and simple so you understand exactly how sleep fits into your fertility puzzle.
The Connection Between Sleep and Hormones
Your body possesses an internal clock known as the circadian rhythm. It also influences hormone production and assists in controlling your sleep-wake cycle. By having good, quality sleep on a regular basis, your body will be able to release the hormones in a beneficial, normal way. However, when you disrupt your sleep, typically because you are going to bed late, waking up at unusual times, or generally not getting enough sleep, your hormone levels may also be altered.This is particularly significant when your desire is to conceive, as fertility relies more on the hormones such as:
- Oestrogen and progesterone (responsible for ovulation and preparing your uterus for pregnancy)
- Luteinising hormone (LH) and follicle-stimulating hormone (FSH) (which help in egg development and release)
- Melatonin (a sleep hormone that also protects your eggs from damage)
- Cortisol (your stress hormone, which can interfere with reproductive health if it's too high)
How Sleep Affects Ovulation
One of the most direct ways poor sleep impacts fertility is through irregular ovulation. To get the egg released each month, your body requires proper hormonal cues. When you do not sleep well, your body may not secrete enough amounts of LH or FSH, and this may slow or even prevent ovulation.Another problem you may find is that there are also irregular periods, and it is more difficult to follow your cycle to determine your fertile time. And when you are not ovulating regularly, your likelihood of getting pregnant naturally will be lower.
Melatonin – More Than Just a Sleep Hormone
Melatonin is the hormone that you have likely heard causes you to fall asleep. But what you may not know is that it preserves the health of your eggs.Melatonin is an antioxidant that protects your eggs against stress and toxins. Your body itself can produce melatonin in a dark and sleeping state. Disrupted sleep or exposure to light (as on phone screens or televisions) can cause your levels of melatonin to decrease.
Less melatonin = higher stress on your eggs = lower egg quality.
Cortisol and Stress Hormones
When you are not getting enough sleep, your body produces more cortisol, which is your primary stress hormone. The elevated cortisol might be made to being a sign that it is not a good time to conceive, thereby causing delayed ovulation or a decreased chance of implantation.In the case of poor sleep over a prolonged period, hormonal abnormalities can develop, and this makes it more difficult to conceive. There is also a chance you may be tired, irritable or anxious, and that may cause further burdens in the fertility process.
How Much Sleep Do You Need for Hormonal Balance?
The number of hours adults require to sleep during a night is between 7 and 9 hours. However, it is not only about the quantity of hours, as the quality of your sleep plays its role as well.Here’s what can help:
- Going to sleep and waking up at the same time every day
- No screens at least 1 hour before bedtime
- Maintaining a dark and quiet bedroom
- Restriction of caffeine at night
- Establishing a peaceful pre-bed ritual (such as reading a book or having a warm shower)
Signs Your Sleep May Be Affecting Your Hormones
You may not always realise that sleep is the issue. But watch out for these signs:- Irregular or missed periods
- Feeling constantly tired, even after sleep
- Difficulty falling or staying asleep
- Mood swings or irritability

Sleep and Male Fertility
Sleep also matters to your partner, in case he is also making an effort to enhance his fertility. Research indicates that men suffer from sperm count, motility, and quality when they do not sleep well. Therefore, improving the quality of sleep is one of the things you can do together over the course of this period.Key Takeaways
