Male infertility
Has the study report recommends that the medical profession should be revised inspection standards for male infertility, sperm should be determined according to the form to reflect the male fertility. The report notes that half a century ago by the World Health Organization on the standards set by the ability of male fertility were made across the board requirement that the sperm count ≥ 2000 million / ml, sperm motility ≥ 50% the number of fertility is normal, which is lower than the numerical is sterile. However, many doctors in the clinic found that some are "sterile" male can give birth to children, and some are "normal" for men but not always when the father, male fertility can be seen, there is a gray area, the gray area as in patients with male infertility treatment is a waste of time and money.
7 University of British co-researcher on 765 infertile men's sperm and has 656 pairs of infertile couples have children, a study to develop a new standard are: sperm count ≥ 4800 million / ml, the activities of a number of ≥ 63%, 12 % of normal sperm morphology is considered to have normal reproductive capabilities; sperm count ≤ 1350 million / ml, the activities of a number of ≤ 32%, normal sperm ≤ 9%, is unable to have children. If the sperm test results between these two, then in a gray area, so that male fertility may have or may not.
The study emphasized that sperm morphology is the best indicator of male fertility, normal sperm should contain an oval-shaped like the head-end and whip the tail of the first round in shape or client is too large, curled tail of the sperm are abnormal of. What is gratifying is that Beijing Tianlun infertility hospital has been carried out this routine examination, which is the clinical treatment of patients with male infertility has a very important guiding significance.
