Which condition can lead to impaired fertility in men?

Impaired fertility in men can result from various conditions affecting the reproductive system. Each of the conditions listed can have an impact on male fertility in different ways.

Hydrocele involves the collection of fluid around one or both testicles. While hydroceles often do not directly impair sperm production or delivery, they can be associated with underlying conditions that might affect fertility, such as infections or tumors.

Epididymitis, which is the inflammation of the epididymis, can lead to decreased fertility. This condition often causes pain, swelling, and potentially scarring of the reproductive structures involved, which can obstruct sperm transport and adversely affect fertility.

Testicular torsion is a surgical emergency involving the twisting of the spermatic cord, which can cut off blood supply to the testicle. If not promptly treated, it can lead to testicular necrosis and significantly impact fertility due to loss of function in the affected testicle.

Since all these conditions can lead to compromised fertility through different mechanisms—whether through obstruction, inflammation, or loss of testicular function—indicating that all of them can impair fertility provides a comprehensive view of the underlying mechanisms at play.
