While it is generally agreed that it
takes two to have a baby and every couple is expected to be in optimum
health to have babies, medical experts claim men are having more
fertility challenge now. Sperm concentration in men is said to have
decreased by a third since 1990s while sperm count is said to have
decreased by half over the past 50 years.
Studies are also showing genetic
abnormalities in sperm particularly in older men. For men therefore,
quantity, quality and motility of spermatozoa are seen as important
factors in fertility.
Since the male factor is a prominent
cause of infertility in couples, sperm donation has become vital in
assisted conception treatment.
A study by the Society for the Study of
Male Reproduction stated that “a male factor is solely responsible in
about 20 per cent of infertile couples and contributory in another 30 to
40 per cent.”
According to experts, even when sperm
numbers are great, a high proportion of men may have DNA damage that
significantly impairs the chances of natural conception. Besides, male
sperm deteriorates with age the same way it does for women.
Studies have also shown that if a man
has poor health, smokes, drinks too much or has a bad diet, it’s very
likely his sperms are also going to be unhealthy
