The epididymis is an elongated and narrow conductive tube that connects the testicles and the vas deferens. It is through this conduit that semen circulates. In addition, the epididymis is the place where the final maturation of the sperm takes place.
Three parts of the epididymis are distinguished:
- largest part of the epididymis.
- place where the sperm mature. This maturation process usually lasts about 10-14 days..
- is where mature spermatozoa are stored until they are expelled to the exterior.
Therefore, sperm aspiration directly from the epididymis could be the solution for men diagnosed with male infertility due to the absence of sperm in the ejaculate (azoospermia). In this case, it would be necessary to resort to in vitro fertilization (IVF).
