It is generally better to go to urinate 30-40 minutes after intercourse to prepare for pregnancy. If you go to urinate early, it will easily cause a large amount of semen to flow out of your body, reducing the chance of conception. After the semen is ejaculated into the vagina, it takes half an hour for liquefaction to occur, and the activity of the sperm is enhanced, so that it passes more smoothly through the cervix and uterus to combine with the egg, making it easy to conceive. For women who have difficulty in getting pregnant, pay attention to the fact that after having sex, do not urinate early and rest more in bed, especially for a posterior uterus, you can use a pillow or quilt to put your buttocks up, and sperm will also easily enter the uterine cavity to improve the chances of conception. If you have not been pregnant for a long time after adjusting the way, you should go to the hospital for examination as early as possible.
