Some sports can have an effect on ovulation or sperm quality. Deep-sea diving, for example, can lead to a drastic decline in sperm quality.
For women, exessive exercise can result in the absence of ovulation and menstruation (due to a lack of body fat). However, there are no known data on the impact of normal sports practice on IVF/ICSI treatment. Therefore, if you practice a sport, you can continue to do so, in moderation. The important thing here is to listen to your own body, its limits and its needs.
Sufficient exercise is important for good health, even during pregnancy. If you exercised regularly before you became pregnant, you can continue to do so in the first trimester. If you did not exercise before you got pregnant, you should start a moderate fitness programme, but only in the second trimester. Eat appropriate and varied meals, drink plenty of water and avoid exercising in hot weather. Low-impact movements (walking, swimming, cycling) are preferable. Avoid supine exercises and exercises involving repetitive or jerky movements, especially in the third trimester. Avoid contact sports and sports with a high risk of falls or impact trauma. Ball sports also pose a moderate risk. Due to the risk of oxygen deprivation, mountain climbing and deep-sea diving are not recommended.
