Is it possible for me to get pregnant if I only have one fallopian tube? What if I have neither of them?

The uterine tubes (or fallopian tubes) are muscular tubes leading from the ovaries into the uterus. The uterine tubes are responsible for collecting the egg each month. Fusion between the egg and the sperm (fertilisation) also takes place inside them. The resulting embryo is taken to the uterus where the pregnancy will evolve. Evidently, the fallopian tubes fulfil essential roles in natural reproduction linked to ovulation, fertilisation and pregnancy. In fact, diseases or abnormalities in the uterine tubes are the cause of up to 30% of all cases of sterility. […]

A less invasive, simpler technique: SOFT IVF or MINI IVF

Having a sufficient number of mature egg cells is one of the key steps to obtaining excellent results in a cycle of in vitro fertilisation (IVF). In order to achieve this, the ovaries need to be stimulated and, contrary to what happens during a natural cycle, the ovaries need to simultaneously mature an appropriate number of eggs.
The most commonly used stimulation protocols are based on the use of doses of follicle-stimulating hormone (FSH). These may or may not be administered along with other drugs and vary between 150 and 300 IU/day. The response will be somewhere between 7 and 15 follicles. […]

The adventure of deciding to become a single mother: maternity alone

If becoming a parent is an adventure in itself, taking the step to become a single mother by choice is undoubtedly a challenge. Nowadays, nobody is surprised when a woman decides to have children by herself. It is a decision she takes after having thought long and hard about it. The future mother needs to feel that she is in no way alone during the process. Instituto Bernabeu has been helping women who decide to become single mothers using assisted reproduction treatment for years. The clinic has a team of specialists who, as well as having an in-depth scientific understanding of the situation, bring a very human touch to the sensitive issue of choosing to be a single parent.

In Vitro Fertilisation (IVF). What are the potential complications?

In vitro fertilisation is the most common form of reproductive medicine and, since the issues which need to be solved are often complex, it is not always possible to get the desired result.
Over the last few decades, the risks associated with in vitro fertilisation (FIV) have gone down considerably. […]

How long should I wait following unsuccessful assisted reproduction treatment?

We are often asked this question at our clinic because, following an unsuccessful attempt at in vitro fertilisation there is always the hope of another go. The recommendation has always traditionally been to leave a space of 3 months between each ovarian stimulation, which can be stressful for patients whose age is against them.
Research has been carried out with the aim of determining whether or not a wait is necessary. The studies compare a wait of one month with a wait of three months and the results obtained are the same.
It is for this reason that we do not recommend putting off a new attempt for more than one month in patients who need to carry out treatment as soon as possible. […]

The importance of the Fallopian tubes in fertility

The Fallopian tubes are two, very thin elongated structures measuring around 12 centimetres in length which connect the peritoneal cavity to the uterus. In this external abdominal part, they are in very close contact with the ovaries.
The Fallopian tubes play a vital role or function in human reproduction: in the first instance, they are responsible for suctioning the egg from the ovary each month and later for waiting 24-72 hours for fertilisation. Should this not happen, the egg is simply absorbed. If it is fertilised, the Fallopian tube allows the fertilised egg to travel to the uterus thanks to contractions and to the hair cells lining it. The fertilised egg (or zygote) remains in the Fallopian tube for around 48-72 hours on its journey to the uterus where it will eventually implant the embryo. […]

Empty follicle syndrome

In vitro fertilisation (IVF) techniques aim to generate multiple follicles (ovarian stimulation) from which to obtain eggs which will later be fertilised. The ovarian stimulation process culminates with the use of a drug which induces the final stage of egg maturation. The most commonly used one is human chorionic gonadotropin (hCG). This final step is essential in order to obtain eggs during ovarian puncture and it also indicates when the procedure should be carried out. The origin of empty follicle syndrome (EFS) is not fully understood and, when it occurs, no eggs are obtained following meticulous ovarian puncture, despite adequate follicle growth following ovarian stimulation and normal hormone results. […]

Will my frozen embryos survive?

Cryopreservation, or embryo freezing, is an essential part of courses of assisted reproduction treatment since it means that embryos can be preserved in order to be used at a later date and without the passing of time having a negative impact on their viability.
Embryos obtained as a result of in vitro fertilisation (IVF) may be thawed for a number of reasons: […]

Prenatal care following endometriosis

Endometriosis is a common disease. In most cases, it is difficult to diagnose and is closely linked to infertility. Instituto Bernabeu understands this and its Endometriosis Unit aims to ensure earlier and more accurate diagnosis using the very latest techniques. These range from ground-breaking biochemical markers to analyses of the realistic images provided by three-dimensional ultrasounds.
Once a longed-for pregnancy has been achieved, is prenatal care any different in these cases? […]

What is a hydrosalpinx and how will it affect my fertility?

The tubes connecting the ovaries and the uterus are known as the Fallopian tubes (or uterine tubes). These structures play an essential role in natural reproduction and are responsible for receiving the egg each month and, furthermore, it is here that the union between egg and sperm takes place (fertilisation). They also enable the resulting embryo to be transported to the uterus which is where pregnancy will take place.
A hydrosalpinx is the result of an obstruction at the far ends of the Fallopian tubes which leads to the area becoming filled with liquid. This can lead to the Fallopian tubes becoming very swollen and distended, resulting in a ‘sausage-like’ appearance. In many cases, the obstruction and the liquid that has accumulated impair correct functioning of the Fallopian tube: semen does not travel up, the egg is not received by the tube and fertilisation does not take place, making achieving a natural pregnancy complicated (particularly so if both Fallopian tubes are affected). Alternatively, a hydrosalpinx can lead to pregnancy occurring within the tubes themselves (ectopic pregnancy). […]
