Male Factors

Recent studies have revealed that the incidence of male infertility is equal to that of female infertility, affecting approximately 40% of infertile couples.

Some causes of male infertility include vasectomy, low sperm count, and the inability to ejaculate. While testosterone production does decline as men age, a link between age and male infertility has not been proven.

Usually, male factors involve age and lifestyle issues or genetic-associated causes.
