Can a man have children with only one testicle?

Men with only one testicle are generally fertile, but their fertility may be affected. In a few cases, there may be problems such as reduced sperm count and abnormal hormone levels.

A single testicle can usually compensate to maintain normal reproductive function. Healthy testicles will make up for the function of the missing side by increasing their size and improving spermatogenesis efficiency. Most people with unilateral testicle loss can still produce sufficient amounts of normal sperm. Common causes include congenital cryptorchidism, trauma or surgical removal. It is recommended to regularly test semen quality and sex hormone levels to assess fertility.

A small number of patients may have fertility problems. If the remaining testicle has a history of cryptorchidism, varicocele, or inflammatory damage, it may lead to oligozoospermia or azoospermia. Abnormal hormone levels may also affect sexual desire and the sperm maturation process. Such cases require semen analysis, ultrasound, and endocrine evaluation to confirm the cause.

It is recommended that men with fertility needs undergo a professional fertility evaluation. Daily avoidance of testicular trauma, regular work and rest, and balanced intake of zinc, selenium and other trace elements can help maintain sperm quality. If abnormal semen parameters are found, you should seek medical treatment promptly. If necessary, sperm cryopreservation or assisted reproductive technology can be considered.
