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).

Techniques for obtaining spermatozoa

There are currently many different solutions when spermatozoa are not present in ejaculate. Access to a trained urologist increases chances of achieving spermatozoa in greater quantities and with improved quality.
What is TESA (Testicular Sperm Aspiration)?
This is a question which many couples ask themselves as they turn to assisted reproduction treatment when the issue is an absence of spermatozoa in semen (azoospermia) with the aim of obtaining sperm. TESA (Testicular Sperm Aspiration) is a technique used for obtaining spermatozoa by testicular puncture.
Modern-day urology means that spermatozoa can be obtained for use in assisted reproduction techniques using different means. Over the last 10 years, we have improved the chances of achieving good results whilst reducing the invasive nature of the process and improving the quality of samples obtained in cases in which this was not previously possible. Men who have undergone a vasectomy, cases in which the sperm duct is obstructed or patients with cystic fibrosis are common examples in which adequate spermatozoa may be obtained through a simple testicular puncture under local anaesthetic. Different types of biopsy are also prescribed in certain cases. The differences between them are as follows: […]

Vasectomies: the male contraceptive

Vasectomies are the most reliable method of male contraception and an estimated 40 to 60 million men worldwide have chosen to have one.  They are the most widely used contraceptive method for men looking to achieve permanent sterility for family planning or personal reasons.
The procedure should be thought of as irreversible. It has a low complications rate and failure is very infrequent. A vasectomy does not begin to work immediately and couples need to continue to use contraceptives until absolute sterility has been achieved. Vasectomies are safe and do not have any side effects or cause serious illness in the long term. It is a method that is used for avoiding pregnancy in long standing relationships but also as a personal sterility method in men who are not in a relationship (those who have separated, divorcees or widowers) but who do have sexual intercourse or, even when they are in a relationship, do not wish to have more children.

The male factor in infertility

In contrast with the old-fashioned belief that reproduction issues are a female thing, current figures are clear: 47% of infertility cases in a couple are down to an issue with the man. Therefore, when a couple has infertility issues and they seek the help of a clinic specialising in assisted reproduction, the tests and analyses are carried out on both members of the couple. This practice of looking into both the female factor and the male factor is now common and carried out by all experts in the field, but there is still a lack of understanding of the fertility issues which men can have. What are they? What solutions do leading assisted reproduction clinics offer nowadays?
The most common issues amongst men are “changes in the sperm count with no apparent cause”, explains Instituto Bernabeu in Alicante. That is, a low number of sperm, poor sperm mobility or abnormal morphology. Additionally, there may be more concrete and identifiable reasons for changes in sperm such as obstruction issues, infection, diseases or genetic reasons which impede egg fertilisation or which affect embryo quality.
