👉 Spermatocele refers to a type of cancer that occurs in the testicles. It's caused by abnormal development of the sperm cell, which can lead to damage or death of the sperm cells and may result in a growth of extra tissue around the sperm cells. This condition is also known as 'zoograft' or 'zoogot'. The exact cause of this type of cancer is not fully understood but it's believed that genetic factors play a role.
