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 […]

The advantages and disadvantages of transferring embryos during a natural or artificial cycle

Embryo transfer to the uterus is the pinnacle of all courses of assisted reproduction treatment. It cannot be left to chance. The endometrium needs to be receptive and facilitate embryo embedding.
The endometrium can be prepared with the aid of drugs (oestrogens) to simulate natural uterine behaviour – a substituted or artificial cycle – or transfer can be carried out whenever biologically most appropriate following ovulation – transfer during a natural cycle. […]

What impact does cholesterol have on my fertility?

Cholesterol plays an essential role in ensuring that our organism works correctly. Its impact on the heart is still given priority in terms of analysis because of the elevated impact and frequency of diseases of this kind.
Whilst all the other areas of influence have been analysed to a much lesser degree, in some cases such as infertility, the effects of this essential component are now starting to come to light.
What is the importance of cholesterol in fertility? […]

What is a progesterone deficit? Administration and side effects

Progesterone is one of the most important hormones in a woman’s metabolism and fertility. It is produced by the ovaries following ovulation during a normal menstrual cycle but when a woman is pregnant the placenta takes over responsibility for production. Its main roles consist of preparing the endometrium (internal layer of the uterus) for implanting a fertilised ovum and sustaining pregnancies.  It also plays an important role when a woman is breastfeeding because it helps to prepare the mammary glands for milk production. […]

New examination aimed at testing couples with recurrent implantation failure

Instituto Bernabeu focusses on providing personalised solutions, particularly in cases of patients with a difficult reproductive prognosis (low ovarian reserve and recurrent implantation failure (RIF)).
Carrying out a number of empirical tests and treatments has, on occasions, been put forward as an option in the case of patients suffering from recurrent implantation failure. The latter have proven to be of questionable efficacy and the former have proven to be of limited or no use.
One of the proposed strategies for patients with recurrent implantation failure (RIF) that is providing many of these cases with solutions, is IVF (in vitro fertilisation) with elective freezing and biopsies on all embryos so that the frozen embryos can later be transferred during a natural cycle. In other words, without any hormone treatment.
It is possible to recreate the conditions under which transfer takes place during treatment of this kind by carrying out a mock cycle and evaluating a series of parameters that can influence transfer success. […]

Recommendations following embryo transfer

Transfer is undoubtedly one of the most important steps in assisted reproduction treatment.
When the patient steps out of the transfer room, a new beginning takes place and the experience will be totally different to what she has undergone up until that point. The embryos have now been transferred and the countdown to the pregnancy test has begun.
It’s important that patients understand that when they go to the toilet to urinate following embryo transfer, the embryos do not ‘fall out’ nor do they get lost since they are situated inside the uterus, a part of the body which is quite different to the one we use for urinating. […]

Fertility Treatment Medication

There are many drugs that are used when a couple undergoes a fertility treatment (IVF, insemination, egg donation, etc.). Some are very simple to use and have virtually no side effects and others are more complex and have greater side effects.
We shall now discuss the most commonly used drugs, what they are and their side effects. It should be noted that most medication is hormonal or works on that level, so that side effects in many cases will be similar to those which a woman may generally feel during her cycle or indeed during pregnancy. […]
