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 […]

Effects of advanced paternal age on fertility

Owing to sociocultural and economic factors, there has been a considerable increase in recent years in the number of men over the age of 35 who wish to have children. As a couple ages, the probability that they will experience reproductive problems increases. The negative effect of maternal age on fertility has been widely documented and we know that fertility diminishes drastically after the age of 39. Maternal aging is also associated with miscarriage, pregnancy complications, congenital anomalies and an increase in perinatal mortality.
However, few studies analyse the effect of  paternal age on success after the application of assisted reproduction technology (ART) and the results they provide are contradictory. It is true that the male reproductive function is less vulnerable than the female where the aging process is concerned, as is demonstrated by the fact that many babies have been born spontaneously to fathers who are in their seventies or eighties. However, some associations have been found in specific studies that relate a negative effect of advanced paternal age with: […]

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.
The World Health Organisation (WHO) has published several editions of the “Manual for the Examination of Human Semen and Sperm-Cervical Mucus Interaction”, the last one in 2010. 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. […]

Using Magnetic Fields to Select Healthy Sperm: MACS (Magnetic Activated Cell Sorting)

It is well known that having the best possible sperm quality is important to the success of assisted reproduction techniques. To achieve this, the lab has to improve sperm quality based on its motility and morphology, selecting the sperm that is considered to be the best.
However in every ejaculate sperm with abnormal membranes are found, which are programmed to “die”. This process is called apoptosis, or programmed cell death.   Approximately 20% of sperm in subfertile patients are  thought to be in the process of “celular death”. […]
