When one starts an in vitro fertilisation (IVF) treatment, one of the most frequent concerns is the number of high quality embryos that can be obtained.
This number is variable and depends on several factors such as the ovarian reserve and gamete quality (egg and sperm). Once the eggs are fertilised, they are considered embryos, which begins after their early division. The embryo division is observed in the IVF laboratory on a daily basis and is key information to determine the embryo quality. The Spanish Association of Reproductive Biology (ASEBIR) establishes a classification according to various observed morphological parameters, which indicate the embryo quality according to their capacity to implant in the womb.

Scientific evidence from the last 15 years shows that without a doubt, environmental toxins before conception and during pregnancy cause long-lasting effects on reproductive health. An example of this is the exposure to mercury, which causes cognitive impairment in children. Another example is the exposure to agricultural pesticides, which is associated with sperm quality alterations and higher incidence of testicular and prostate cancer for men, and in women it interferes with the development of puberty, ovulation, fertility and menopause.

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”. Continue Reading »
Multiple pregnancy is, along with ovarian hyperstimulation, the most significant complication in fertility treatments.
Most couples that go through assisted reproduction techniques consider multiple pregnancies to be desirable or the lesser evil. However, pregnancies of twins and even more so triplets are associated with a series of complications that challenge the pregnancy ending in the birth of a healthy baby. Let us not forget that the birth of a healthy baby is the only objective of assisted reproductive techniques. Continue Reading »
At first glance, the embryo transfer seems to be the quickest and simplest step in the In Vitro Fertilisation (IVF) process. However, it is actually the most critical step in the entire treatment. Successfully overcoming previous hurdles means nothing if the embryo transfer is not done well. This happens if too much time lapses between when the embryo is taken out of the incubator and when it is placed back in the uterus. Continue Reading »
Instituto Bernabeu has always been loyal to its patient care philosophy, and is even more so now in these current hard times, by planning and implementing new projects and services aimed at helping couples achieve their dream of parenthood.
One of the most controversial questions for patients looking for egg donation is whether or not the eggs are fresh, and if this makes a difference.
With the use of cell vitrification during recent years, survival after thawing has improved greatly for sperm and embryos. However, the size of an egg (the largest cell in the human body) makes it more susceptible to thermal stress. Therefore the rate of survival is not as high, and it is possible that certain cellular structures suffer in the freeze-thaw process. Continue Reading »
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! Continue Reading »
The information that we can offer online does not replace the direct professional opinion of the doctor after a comprehensive assessment of your personal case and medical history. Therefore, we encourage your to request an appointment with our medical team either in person or through an online video conference if you are unable to travel to one of our clinics in Alicante, Elche, Cartagena or Benidorm.
