Customer Question

During ejaculation, do both testicles produce sperm? Eg: should one have had a varicocelectomy 8 years ago, will the other testicle (vas/spermatic cord) be viable?

Is your question is if on one side there was varicocele & operation was done, whether the other side will produce sperm? Please write your query in details.

In otherwords, should a specimen present with no sperm, is there a chance that the only the compromised (left) testicle produced the sample or will the ejaculation be produced from both testicles. Basically if a specimen presents with no sperm, is the likelihood that the person is sterile? .... Male, 32 years, excellent health, non smoker, no significant family history...

Was any sample taken before the operation? Was there any disease like varicocele on the nonoperated site?
Customer: replied 8 years ago.
Sadly no. Can sperm then be extracted from the right testicle for the hopes of IVF? What we have now is an unfortunate "sperm less" sample..
Expert:  Dr Su S replied 8 years ago.
Thank you for the input.

Sperm is produced in both the testicles. It then travels through the spermatic cord . Varicocele is a frequent cause of male infertility. Because it diminishes the blood supply of the testis. When there is obstruction or interruption of continuity of the cord as after vasectomy then the aspiration can give sperm for IVF. Still you can discuss with urologist about the issue.

Hope this information will help you.
Wish your healthy life.

Okay but is there only one spermatic cord? I thought there were two as there are 2 vas... Can there be sperm in the unaffected testicle????
Expert:  Dr Su S replied 8 years ago.
No, there are two spermatic cords , one from each testis. There are 2 vas deferens as you thought of . Vas deferens is a part of spermatic cord. If there were sperm on the unaffected side it should come in the semen through the unaffected vas of the cord. Please read the resource & the pictures of it.
