When I had intercourse with my lover last week, my penis was erect and I tried to enter two or three centimeters without a condom, but there was no ejaculation, just some discharge at the glans. At the time, I thought the discharge was for lubrication, so I didn’t pay much attention to it. But today my wife said that she was late for her period and that there was a possibility that she was pregnant. Can male discharge cause a woman to get pregnant? This situation may cause the wife to become pregnant. Because the male secretion before ejaculation contains sperm, even if the man does not ejaculate in the vagina during sex, a small amount of sperm may enter the woman’s body with the secretion, and if the woman is ovulating at this time, the chances of pregnancy are very high. This type of contraception is very similar to in vitro ejaculation. In vitro ejaculation is the practice of artificially interrupting intercourse and expelling semen outside the woman’s vagina at the moment when intercourse is close to orgasm and ejaculation is imminent. Not only is this method of contraception prone to failure, it also tends to cause functional non-ejaculation, premature ejaculation and erectile dysfunction. If you do not intend to have children, it is better to choose more reliable methods of contraception, such as wearing condoms after erection, oral contraceptives, etc.
