Study: Women Decline Sperms If They Are Not Compatible
According to a study, some sperms are unsuccessful to strike a chord with the female reproductive area and whilst a man might seem to be fertile, his semen can be declined by a woman, if it's not well-suited.
Study Author Sarah Robertson, Professor at the University of Adelaide's (UA) Robinson Institute says that this is more expected to take place if a woman has not formerly come in contact with his sperm over a long span of time.
Robertson said, "We used to think that if a woman couldn't get pregnant, and the man's semen test was normal, the problem lay with the woman. But it appears this is not always the case".
The fertility expert is fronting a national research plan probing the movements of semen in the cervix and uterus after sexual intercourse occurs.
She says that they have found that sperm does not just fertilize an egg. Semen has unique features, which add to a fit pregnancy, together with aiding to make the female body ready for taking care of the fetus.
Robertson says that it includes indicating molecules that are accountable for setting off immune changes in women so that they can allow the entry of an unfamiliar substance in the body, in this case sperm, resulting in conception and a healthy pregnancy.
