Semen quality parameters according to the World Health Organisation (WHO)

01The spermiogram is a basic tool that provides us with some of the best information to assess male fertility. It is also very useful in order to formulate a personalized treatment plan for the couple.

The World Health Organisation (WHO) has published several editions of the “Manual for the Examination of Human Semen and Sperm-Cervical Mucus Interaction”, the last one in 2010. Those manuals help and guide andrology laboratories to determine sperm quality. Moreover, in recent years, the European Society for Human Reproduction and Embriology (ESHRE) in collaboration with the WHO have developed a program to improve standardization between laboratories in terms of sperm sample diagnosis and assessment criteria.

Contamination, environmental toxins and fertility

Instituto BernabeuScientific evidence from the last 15 years shows that without a doubt, environmental toxins before conception and during pregnancy cause long-lasting effects on reproductive health. An example of this is the exposure to mercury, which causes cognitive impairment in children. Another example is the exposure to agricultural pesticides, which is associated with sperm quality alterations and higher incidence of testicular and prostate cancer for men, and in women it interferes with the development of puberty, ovulation, fertility and menopause.

Using Magnetic Fields to Select Healthy Sperm: MACS (Magnetic Activated Cell Sorting)

MACS Instituto BernabeuIt is well known that having the best possible sperm quality is important to the success of assisted reproduction techniques. To achieve this, the lab has to improve sperm quality based on its motility and morphology, selecting the sperm that is considered to be the best.

However in every ejaculate sperm with abnormal membranes are found, which are programmed to “die”. This process is called apoptosis, or programmed cell death.   Approximately 20% of sperm in subfertile patients are  thought to be in the process of “celular death”. Continue Reading »

Azoospermia in the IVF lab

Azoospermia is defined as the absence of sperm in the ejaculate, which is generally classified as either obstructive or secretory. In obstructive azoospermia, the sperm cells cannot complete their journey from the testicle to the urethra through the seminal tract; however, the sperm cells are produced in the testicle (spermatogenesis).

Spermiogramme and Advanced Semen Studies (FISH AND TUNEL)

A seminogramme or spermiogramme is one of the basic studies performed on men to determine the sperm quality. Sperm is analysed from both a macroscopic and microscopic viewpoint. The most relevant parameters of the study are threefold:

-          Sperm count

-          Sperm motility

-          Sperm morphology
