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. […]
Achieving pregnancy when pregnancy does not come is one of the challenges the medical team at Instituto Bernabeu faces every day. One of the most important challenges of female infertility is implantation failure. The embryo does not get to nest in the maternal uterus or it does but the woman undergoes an early miscarriage, which produces a great frustration. The couple should put themselves as soon as possible in the hands of the specialist and not leave to chance or wait the passage of time to solve a situation that requires a personalized study.
Instituto Bernabeu Medical Director, Dr Rafael Bernabeu explains: “The causes of implantation failure are multiple, but contrary to the general opinion, patients believe they are causing the problem when, in fact, to a great extent the problem is embryonic”. Therefore, the medical centre global benchmark in reproductive medicine develops a study of the three patients: “The mother, the father and the embryo.” Twenty-five percent of embryo implantation failures cases, “do not have a clear cause” and in many cases, there is a combination of factors that can be combined, warns Dr Rafael Bernabeu. Not only are environmental and immunological factors, they are also due to the intake of certain foods and even to the cosmetics used. “We are exposed to tens of thousands of chemical substances and many generate disorders and among them may be the cause of repeated miscarriage and implantation failure,” says Dr Bernabeu.

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”. […]
A seminogramme or spermiogramme is one of the basic studies performed on men to determine the sperm quality. Sperm is analysed from both a macroscopic and microscopic viewpoint. The most relevant parameters of the study are threefold:
– Sperm count
– Sperm motility
– Sperm morphology
