How long it takes to get pregnant after intercourse is very much related to the time of intercourse and whether the man and woman have any factors affecting pregnancy. If you have intercourse during ovulation, and the man and woman check that there are no factors affecting pregnancy, you may get pregnant on the same day. On the contrary, some people may not be able to get pregnant all the time.
In a woman’s menstrual cycle, there is only one ovulation, and the egg can survive for 12 to 24 hours, so intercourse during ovulation will increase the probability of pregnancy. Men with oligospermia, weak sperm and abnormal semen liquefaction are prone to infertility. Women with ovulation disorders or blocked fallopian tubes may not be able to conceive even if they have intercourse together for a long time.
Without these influencing factors, most couples who have intercourse during ovulation will usually get pregnant in 3 to 6 months.
Very few couples will fail to conceive for some unknown reason. If you have had normal sex for a year and have not conceived, you need to see a doctor.
