The link between thrombophilia and recurrent implantation failure

The percentage of pregnancies achieved following assisted reproduction treatment has progressively increased over the years but we still have a long way to go before we achieve optimum results. This is why alternative treatment options that have not already been attempted are taken into account when several courses of treatment have not given a positive result.

It has been […]

What role does the immune system play in fertility?

From an immunological point of view, pregnancy is a unique set of circumstances because a woman’s body has to ‘withstand something that is foreign to it’. The mother has to carry the embryo and, in order to do so, her immune system needs to accept co-existence with cells that are at least half foreign in origin. Using a […]

Uterine contractions: a challenge for embryo implantation

We are not yet fully aware of the exact reasons why sometimes a pregnancy happens and sometimes it does not. The embryo implantation process is an entire set of processes, many of which are unknown.

Based on the fact that the main factors that have an impact on implantation are the embryo and the female uterus, huge progress has been made […]

What is the corpus luteum?

After ovulation, follicles transform into the corpus luteum or ‘yellow body’. Corpus luteum development depends on the luteinising hormone (LH) surge before ovulation and on the number of receptors for this gonadotropin in the granulosa cells and in the theca cells.  Both types of cells go through significant changes in structure and composition and this turns the walls of the corpus […]

What tests do I need to have before egg donation treatment?

Egg donation has become an option for women who, for whatever reason, can no longer use their own ova. For example, due to poor ovarian reserve, poor oocyte quality and premature menopause.

The process is widely used in Spain. As well as exceeding organ
donations and transplants in number, we also have the largest number of egg
donors in Europe.

Can patients manage embryo and gamete transportation?

Whilst it is not part of the day-to-day routine at reproductive
medicine clinics, it is now increasingly common to have to transport biological
samples (oocytes, semen or embryos) from one clinic to another and even from
one country to another.

There can be several reasons for this such as the following:

– The
couple wishes to continue their treatment in a […]

to make their dream of becoming parents come true. In cases such as these, the
couple tends to have common and understandable doubts about reproduction

Progress in treatment for patients with poor ovarian response

Personalising courses of treatment is undoubtedly currently the
most important area of change in the field of medicine. A specific strategy should be designed
depending on each patient’s individual characteristics.

One of the key areas for developing personalised medical healthcare is the use of pharmacogenetics. A patient needs different doses or types of pharmaceutical drugs depending on certain genetic variations. […]

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 […]
