Parotitis, more commonly known as “mumps”, is a contagious viral disease that affects one or both parotid glands (major salivary glands) situated behind the ascending rami of the mandible. It is caused by the mumps virus and typically affects children and teenagers, although it may also cause infections in sensitive adults. In general, the disease produces lifetime immunity, and it may be prevented by the administration of the combined MMR vaccine. Mumps may affect other glands in the body, the central nervous system and the testicles. The most frequent complications are meningitis and testicular inflammation which may lead to infertility. This inflammation of the testicle is also known as mumps orchitis. It is not very frequent, affecting 1 per million inhabitants per year among the general population. […]
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. […]
Teratozoospermia is an increase in the percentage of abnormal sperm in a sperm sample and it is identified by means of a seminogram or semen analysis.
According to the criteria in the 5th edition of the World Health Organisation (WHO), 2010 manual, a man has teratozoospermia when the percentage of normal spermatozoa in the ejaculate is below 4%.
Defects in sperm […]
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. […]
We’re dedicating this Instituto Bernabeu forum topic to a very common technique used in the human reproduction laboratory: ICSI or Intracytoplasmic sperm injection. We have prepared this explicative video on the topic, in which Dr. Jorge Ten simply explains what this technique involves, how it is performed, its indications, history and evolution, as well as our reproductive biology team’s efforts to perfect the results. We hope you like it! […]
Klinefelter’s Syndrome is considered the most common chromosomal abnormality in humans, with an incidence of 1 out of every 500 newborn males. Those affected by this syndrome have an extra X chromosome, which leads to primary testicular failure and therefore infertility and hypoandrogenism.
