Oligospermia is a medical term specifically used to describe a condition where there is a low sperm count in a man’s semen. The World Health Organization defines oligospermia as having fewer than 15 million sperm per milliliter of semen. A low sperm count can impact fertility and is one of the common causes of male infertility.

This condition can arise due to various factors, including hormonal imbalances, genetic issues, lifestyle factors (such as smoking or obesity), and environmental factors (such as exposure to toxins). Understanding oligospermia is essential in the field of oncology and reproductive health, as some cancer treatments can also affect sperm production, leading to oligospermia.

The other choices, such as decreased libido, increased testosterone, and high sperm count, do not accurately describe oligospermia. They relate to different aspects of male reproductive health and hormone levels but are not synonymous with low sperm count.
