According to Medicalnewstoday, there is no definitive answer to the question of how long a woman should stay in bed after intimacy for the sperm to fertilize her egg. Some experts suggest that there is no need for a woman to stay in bed for a specific amount of time, while others recommend a period of 10-15 minutes.
The reason why some experts recommend staying in bed for a short period after intimacy is to allow gravity to help the sperm reach the egg. When a woman is lying down, the sperm are more likely to swim in the right direction towards the egg. However, it is important to note that this is only a small factor in the likelihood of conception and is not the only determinant of successful fertilization.
In addition to gravity, other factors such as the quality of the sperm and the timing of ovulation play a crucial role in determining the success of fertilization. Sperm can survive in the female reproductive tract for up to five days, so it is important to have intercourse around the time of ovulation to increase the chances of fertilization.
According to Medicalnewstoday, it is important to note that the female body has a natural mechanism that helps to draw sperm towards the egg. The contractions of the uterus and the movement of the cervix help to propel the sperm towards the egg, even when a woman is not lying down.
In conclusion, while staying in bed for a short period after intimacy may help to increase the chances of fertilization, it is not a guarantee.
