What is orchitis? What impact does it have on male fertility?

Mumps rubalavirus leads to an illness during infancy that is commonly known as mumps and that can, in some cases, affect male fertility and lead to male fertility issues.

In cases such as these, the illness can affect the testes by
between 25 and 40% and this poses an added complication. This condition is
known as orchitis.

It mainly affects boys over […]

Temperature and Semen Quality

It is common knowledge that a seminogram is one of the basic tests that couples who are having issues getting pregnant. In other words, the male partner’s semen needs to be analysed in order to check certain parameters such as the quality of spermatozoa in ejaculate, their motility, their morphology and so on. The aim is to […]

AIDS. Assisted reproduction is the best option

The risk of contracting HIV during unprotected sexual intercourse is estimated to be between 0.5 and 1%. For serodiscordant couples (one partner is a carrier), trying for a child naturally can entail an elevated risk of transmission. In cases such as these, assisted reproduction techniques are an excellent choice for getting pregnant without the risk […]

DNA fragmentation in sperm: TUNEL

When a couple fails to get pregnant or has an unsuccessful pregnancy, a number of tests performed on both partners is recommended. One of the basic tests in analysis of the male partner involves performing a seminogram or spermiogram that provides us with an initial indication of semen quality. This information can be supplemented with a sperm DNA fragmentation analysis, should this be considered necessary.
The DNA fragmentation test is a technique that supplements a study of the male factor in certain cases. […]

Infertility in men and cryptorchidism

Cryptorchidism, from the Greek words kriptos (hidden) and orquis (testicle), is the failure of one or both testes to descend to the scrotum. It is estimated that between 2 and 5% of newborn boys have this abnormality although the figure rises to 30% when premature boys are taken into account. In many cases, the issue resolves itself naturally and, as a result, at one year of age, only 1% of boys have the condition. […]

The impact of cannabis on semen

Today’s post aims to explain the conclusions drawn from research performed by the Biology Department at Instituto Bernabeu in Alicante in collaboration with the Biotechnology Department at the University of Alicante. The work in question was awarded the ICIRA prize for research. The study looked into the effects of cannabinoids (marijuana derivatives) and substances that are produced by our organisms (endocannabinoids) on male fertility. […]

Seminal lavage in males with HIV

Human immunodeficiency virus (HIV) is a retrovirus and, during its most advanced stage of infection, it leads to acquired immunodeficiency syndrome (AIDS). Whilst there is currently no cure for HIV/AIDS, antiretroviral treatments do exist that stop the symptoms from developing or delay them until later. As such, we come across increasing numbers of couples of childbearing age who wish to have children and in which one of the partners is a carrier of the virus. […]

Sperm capacitation

The spermatozoa in ejaculate need to have gone through a process known as sperm capacitation in order to obtain the ability to fertilise. This happens naturally in the female reproductive system and techniques in order to make it happen in the laboratory have been undergoing development for many years.

“In vivo” sperm capacitation

In vivo capacitation takes […]

Mumps and male infertility

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. […]
