Doctors in India disclosed that the sperm count of a fertile Indian male had decreased by a third over a span of three decades. Some factors may include exposure to high temperatures at places such as factories. A 1 degree increase in temperature will reduce 14% of spermatogenesis.Researchers in Calcutta conducted a study between 1981 and 1985 that also showed a decrease in sperm motility and seminal volume, but no change in sperm concentration. Society and culture
There are a variety of social stigmas that surround male infertility throughout the world. A lot of research has pointed to the relationship between infertility and emasculation. This association has led to infertility being less studied and diagnosed in men over time. In places like Egypt, Zimbabwe, and Mexico, erectile dysfunction also known as impotence, is considered a determinant of infertility. When stereotypical ideals of manhood are virility and strength, men sharing problems of infertility can face feelings of inadequacy, unworthiness, and have thoughts of suicide. In many cases, a variety of socio-economic interventions come in play to determine penile activity. For the Shona people, since impotence is linked to infertility, an examination to check on the penile function spans from infancy to post marriage. At infancy, there are daily check-ups by the mothers on the sons erection and urine quality. When the son reaches puberty, they are asked to ejaculate in river banks and for their male elders to examine sperm quality.
The traditions last until post-marriage, when the family of the bride take part to check on consummation and the grooms sperm quality. Crisis
