Does sleep affect fertility?
Sleep is essential for our wellbeing; without it, we cannot function. It is just as important as breathing, eating and drinking. Depending on individual needs, some may require more sleep than others. However, if you are having difficulty conceiving, you might be surprised to learn that your sleep patterns could be affecting your fertility.

The role of sleep in health
Sleep is crucial for both physical and mental restoration, allowing our bodies to recharge. Getting a good night’s sleep offers several benefits, including maintaining a healthy immune system, boosting energy levels and positively impacting mental health. Additionally, good quality sleep can help reduce stress and alleviate anxiety.
Conversely, prolonged poor sleep can increase the risk of chronic health issues, such as heart disease, high blood pressure and diabetes. Overall, insufficient sleep can impair brain function, affecting concentration and clear thinking, while also playing a key role in fertility.
How sleep affects hormones
Getting a good night’s sleep is vital for hormone production, and insufficient sleep can lead to hormonal imbalances.
Melatonin – Commonly referred to as the sleep hormone, low levels of melatonin can result in sleep disturbances and lead to fatigue, concentration difficulties, mood swings, muscle and joint pain.
Human growth hormone (HGH) – Inadequate sleep can limit HGH production in your body. The limitation makes the body more vulnerable and less capable of self-repair, especially after injuries. Additionally, a decrease in HGH levels may also contribute to weight gain.

Hunger hormones – Leptin, ghrelin and insulin are hormones that help regulate hunger and appetite. Lack of sleep can negatively impact your appetite, potentially leading to weight gain. It can also impact insulin levels, which can exacerbate diabetic symptoms.
Stress hormone – Cortisol, known as the stress hormone, helps the body manage stress by raising blood sugar levels, enhancing brain glucose availability and supporting tissue repair. It also plays a key role in maintaining blood pressure and immune function. Poor sleep can disrupt the release of cortisol, leading to issues such as weight gain and high blood pressure.
Does lack of sleep affect fertility?
Sleep plays a crucial role in reproductive health for both men and women. Ensuring you get enough sleep is essential for increasing your chances of conceiving, especially for those considering or undergoing IVF treatment.
Sleep and female fertility
Insufficient sleep can impact female fertility in several ways. It can disrupt the menstrual cycle and impact the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), both of which are essential for initiating ovulation and releasing an egg from the ovaries. Additionally, lack of sleep can alter the production of oestrogen and progesterone, which are vital for conception.
Sleep and male fertility
For men, sleep deprivation can negatively affect sperm production and motility. It can lower testosterone levels, which are essential for sperm production. Furthermore, lack of sleep may lead to anxiety and depression, both of which can reduce the chances of conceiving.
It is generally recommended to get about seven to nine hours of sleep each night, although individual needs may vary. There are several ways to ensure you get good quality sleep, including limiting caffeine intake, staying active through regular exercise and avoiding electronic devices before bed. Don’t worry, if this is a concern, we can discuss how to improve your sleep during your consultation.
When is the right time to seek help?
The earlier, the better. If you have any concerns about your sleep or fertility, it is important to contact your doctor or fertility clinic. Remember, sleep is just one piece of the puzzle that influences fertility. Other factors include diet, lifestyle choices and age. Rest assured, we will talk to you in detail and determine a suitable treatment to achieve the best possible outcome for you.
