oligozoospermia

What is hypospermia? How can it be detected? How does it affect my fertility?

The World Health Organization (WHO) indicates that a man has hypospermia when the semen sample he produces when he ejaculates is below 1.5 mL. A semen analysis needs to be performed in order to obtain a diagnosis. This test measures different semen parameters such as the volume of the ejaculate, the number of spermatozoa, sperm mobility and so on.

In order […]

Y chromosome microdeletion: Male sterility and genetic material loss diagnostic technique

We all have 46 chromosomes: 23 of them are inherited from our father and 23 are from our mother. The genetic information for our entire body is stored within these chromosomes. Two of the 46 are sex chromosomes and determine whether we are male (XY) or female (XX). Therefore, the Y chromosome contains all the necessary information for differentiating males from females as well as for sperm production.

What is the Y chromosome microdeletion analysis about?

The study of Y chromosome microdeletions consists of checking if chromosome Y is complete and, as such, has all the necessary information for satisfactory sperm production or if, on the contrary, small fragments are missing. The loss of such fragments leads to altered spermiogramme which can mean poor sperm production (oligozoospermia) or even no production at all (azoospermia).

What are the main causes of male sterility and infertility?

The male partner’s role in infertility has, historically, been undervalued and underdiagnosed for cultural and social reasons. However, we are now seeing progress in the analysis of men and a growing interest amongst patients in their fertility issue. Consultations for men with difficulties having children are increasingly common.
The causes of male sterility (male factor) have seen a significant increase over the last few years and are now responsible for up to 50% of cases of sterility in couples. Up to 30% of cases of infertility are due to the male factor alone and in a further 20% of cases there is a combination of both male and female factors. This is why urological examination of the male partner is so important during the couple’s fertility analysis. […]

How are seminograms interpreted?

A seminogram, or semen analysis, is a basic analysis of a semen sample with the aim of determining semen quality. In order to carry out the analysis correctly, the patient needs to refrain from sexual intercourse for a period of 3 to 5 days. That is, he must not ejaculate during that period and the sample must be obtained by means of masturbation.
The most relevant parameters evaluated in a semen sample include: […]

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? […]
