Asthenozoospermia: What is it? How can it be detected? What course of treatment can be used in order to get pregnant?

Asthenozoospermia is a decrease in the percentage of motile sperm in a sperm sample and it is identified by means of a seminogram or semen analysis.
Nowadays, seminograms are a basic tool which provide us with information in order to evaluate a man’s fertility and they are very useful when determining personalised treatment for the couple concerned. The analysis can be used to evaluate numerous factors such as the concentration, motility and morphology of sperm present in the ejaculate, amongst others.
According to the criteria included in the 5th edition of the World Health Organisation (WHO) (2010) manual, a man has asthenozoospermia when less than 32% of sperm in the ejaculate have progressive motility (sperm which move around) or when there it less than 40% total motile sperm (motile sperm which do and do not move around).

Male fertility tests

When a couple is faced with difficulties getting pregnant, there is approximately a 50% chance of the reason for this being a factor in the male partner.
The main cause of fertility issues in men is poor semen quality. Therefore, various parameters in semen need to be analysed in order to determine what the quality of the semen is. Two parameters are particularly important: the concentration or quantity of sperm in semen and their motility. This needs to be adequate in order to ensure that the egg is fertilised.
There are several quick tests available on the market. They are similar to female ovulation tests and they are understood to carefully evaluate semen quality and determine if a man is fertile or not. But are these tests really useful in understanding semen quality? […]

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

The 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.

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.
