Only one testicle can usually produce children if it functions normally.
Whether the man can have children depends mainly on whether the testicle can produce sperm and whether the sperm quality is normal. And the vas deferens should be open and able to ensure that the sperm can be transported. If a man can have sex normally and has normal sperm, even if he has one testicle, he can usually have children.
However, if a man has only one testicle with hypospadias, orchitis, epididymitis, or an incompetent vas deferens, the chances of having a baby may be affected. In addition, the ability to have a child is also related to the female partner. If the male partner’s semen is normal and the female partner’s ovulation monitoring and fallopian tubes are not abnormal, it is possible to have a child.
If the male has only one testicle, it is recommended to go to the hospital for a semen test, ultrasound, etc., and the doctor will give the right treatment according to the test results.
