Omega-3 and testicular volume


In 30-50% of couples with fertility problems the man has poor semen quality. The onset in sperm production begins at puberty, and once it has started, it continues almost constantly until death (although testicular tissue mass decreases with age and this involves changes in sperm production). Sperm quality is measured by the amount, the movement, and the size and shape of sperm.

With respect to the amount, the ejaculates of fertile men can contain up to several hundred million sperm per millimeter, and factors that influence the number of sperm ejaculated include:

  • The sperm production capacity of the testicles is condicioned by testicular volume (the size of testicles directly reflects the quantity of sperm producing tissue they contain, and so the maximum rate at which they are able to produce sperm).
  • The period of time since the last ejaculation.
  • General health (which may affect sperm production).
  • And the structural and functional integrity of the man reproductive tracts.

Outcomes from different studies suggest that dietary fats may influence testicular function. Particularly, in healthy men it has been observed that the intake of omega-3 polyunsaturated fatty acids is positively related to testicular volume, while the intake of omega-6 and trans fats is inversely related to testicular volume.

We leave the reader to draw conclusions.




Healthy diet and semen quality

There is still a common but erroneous belief that infertility is a female problem. Male infertility factors account for approximately 30% of all infertility cases. The most common [...]
