Can you have a baby with only one testicle?

Only one testicle is usually fertile. As long as the remaining testicles function normally, they can still produce sperm of sufficient quantity and quality.

Male fertility mainly depends on the spermatogenic function and hormone secretion of the testicles. Unilateral testicular absence may result from congenital cryptorchidism, trauma, or surgical removal. If the preserved testicles are well developed and there are no other reproductive system diseases, and routine semen examination shows that sperm concentration, motility and other indicators are normal, the probability of natural conception is not much different from that of patients with bilateral testicles. Some patients may have secondary problems such as varicocele and orchitis that may affect their fertility and require semen analysis for evaluation.

In rare cases, when the remaining testicles have severe spermatogenesis impairment or vas deferens obstruction, assisted reproductive technology may be needed. Such patients are often accompanied by azoospermia or severe oligozoospermia, and require testicular puncture and sperm extraction or microsperm extraction, combined with in vitro fertilization technology to achieve fertility.

It is recommended to conduct semen examination and reproductive system ultrasound evaluation before preparing for pregnancy. If abnormal sperm quality is found, drugs can be used to improve the spermatogenic environment in time or assisted reproduction can be selected. Daily testicular trauma, high temperature environment and exposure to reproductive toxic substances should be avoided, and regular work and rest and a balanced diet should be maintained to help maintain testicular function.
