Male infertility due to a post-testicular factor is referred to those agents that affect the spermatozoa, once they have been synthesised, e.g. once they have been expelled out of the testicle.

  • Obstructions in the male reproductive tract, such as obstructions in the epididymis, or the vasa deferentia.
  • Seminal infections, such as prostatitis.
  • Sexual dysfunction.
  • Retrograde ejaculation.

If what is intended is having children, it’s important to know the values of the spermatic capacitation, and is recommended to read the indications of artificial insemination, conventional IVF, ICSI and PGD, to find out which assisted reproductive technique best applies to your case.

Spermatozoa with alterations

In an assisted reproduction treatment, before using the sperm sample, the sperm capacitation must be carried out. It can be performed through several techniques, and consists on selecting the best spermatozoa by separating the motile spermatozoa from the immotile ones.

Once the capacitation has been achieved, a value commonly known as total motile sperm count is obtained. Once this value has been found out, the fertility treatment that best suits each case is performed.
