  2. if a male sperm is pour down from the womans vagina and d man doesn’t have a low sperm count, pls what is d solution of getting pregnant

    • Hi Honeydarm,

      It is normal for some amount of a man’s seminal fluid (semen) to come out of the vagina after sexual intercourse. Semen is the fluid that carries the sperm and is ejaculated during orgasm by the male partner. It is not necessary for the all of the seminal fluid to remain inside the vagina after intercourse. Once the the semen is inside of the vagina, the sperm swim toward the opening of the cervix and make their way to the awaiting ovum (egg) for fertilization. What remains is the seminal fluid (semen), not the sperm. It only takes one sperm to fertilize the ovum. Please rest assured that the sperm are getting where they need to go, regardless if you have seminal fluid leakage after intercourse.

    Is it normal for the sperms of a man to pour down from the womans vagina after ejaculation, if no, what is the problem.

    • Hi frempong,

      This is a very common question. Typically some of the semen (fluid that carries sperm) eventually comes out of the vagina after intercourse, even some right away. This is normal.
