Infertility

"Infertility refers to an inability to conceive after having regular unprotected sex. Infertility can also refer to the biological inability of an individual to contribute to conception, or to a female who cannot carry a pregnancy to full term. In many countries infertility refers to a couple that has failed to conceive after 12 months of regular sexual intercourse without the use of contraception. Studies indicate that slightly over half of all cases of infertility are a result of female conditions, while the rest are caused by either sperm disorders or unidentified factors.
1. About 20% of cases of infertility are due to a problem in the man.
2. About 40% to 50% of cases of infertility are due to a problem in the woman.
3. About 30% to 40% of cases of infertility are due to problems in both the man and the woman."

Reduced sperm motility

A low sperm count is the most common fertility problem for men. After a low sperm count, however, the second most common fertility problem for men is low sperm motility. Low sperm motility refers to a situation in where enough of a man’s sperm do not move forward. If the sperm do not move forward, they cannot make the journey from the vagina past the cervix towards the fallopian tubes, where they can fertilize an egg.
