Can one with one undescended testicle get pregnant?

Patient's question:

I am 24 years old. I feel that one side of my testicles is not right, so I went to the hospital for a detailed gynecological examination. The doctor said it is underdeveloped testicles on one side. I asked myself and feel quite worried. Can one testicle underdevelopment affect fertility?

Doctor's answer:

The development of one testicle in males is not only normal if one testicle grows and develops normally, but also has the ability to reproduce, mainly depending on the quality of sperm. If there are normal sperm with good developmental quality, it is also possible to deliver.
Recommendation: You can refrain from ejaculation for 3-7 days and go to the hospital to have a semen analysis. If the sperm quality is good, it is possible to conceive.
Infantile testicular underdevelopment may be cryptorchidism. It is recommended to diagnose and perform surgery within two years to avoid interfering with future growth and fertility.
