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.

Obesity and fertility

The extent of the issue
Obesity is a public health issue both in the general population and in women of childbearing age. The figures are a proof of this and, far from improving, the problem has been getting progressively worse over the last few years.
Maternal obesity in the United States of America was calculated to be 7% in 1980 and had risen up to 24% by 1999. If we take into account both obesity and excess weight, the available data indicates that the figures were 37.1% in 1999 and 40.5% in 2003.
The NHANES (National Health and Nutrition Examination Survey) reveals obesity figures (BMI or body mass index ≥ 30 kg/m2) in women of reproductive age (20 to 39 years of age) of 31.9%.
In other words, one in every three women of a fertile age is obese. […]

The advantages of comprehensive chromosome screening (PGS/PGT-A/CCS) in women of an advanced maternal age

Women currently seek guidance on reproduction at a much older age than they did some years ago. As a result, amongst the women who undergo fertility treatment, there is a significant group of women of an advanced age and their prognosis is poorer. This is a huge challenge for reproduction specialists. […]

Have I got poor ovarian response? How should I deal with it?

A patient can be classified as having poor response when the number of oocytes obtained during a cycle of in vitro fertilisation is under what was expected. The criteria generally used to label a patient as a poor responder is when 3 or fewer oocytes are retrieved and she has incredibly low ovarian reserve markers (fundamentally, AMH and AFC). […]

Oocyte quality

Oocyte quality is one of the most important of the factors that have an impact on fertility in women. Optimum oocyte quality generally gives rise to embryos with an increased ability to implant in the uterus. […]

Fragile X chromosome syndrome and fertility

Fragile X syndrome is one of the most common causes of hereditary intellectual disability.
The gene responsible for the disease is known as FMR1 and it is found in the X sex chromosome. As a result, both the transmission and the severity of the disorder varies in each sex. As a general rule, men are said to suffer from it whilst women are said to transmit it.
There is a repeat region in the FMR1 gene (expansion) and its size determines whether or not the individual has the disorder or not, as indicated below. […]

Can we have a healthy child if we have hepatitis?

Hepatitis is severe or chronic inflammation of the liver.
There are several possible causes including infections (viral, bacterial or parasitic).
The most common cause is a viral infection and, within these, hepatitis B (HBV) and hepatitis C (HCV) viruses are of particular relevance. It is possible to get infected as a result of contact in blood and contaminated objects (unsterilised surgical material, syringes or needles), due to sexual transmission through mucous membranes and so-called vertical transmission (transmission from mother to child, particularly during childbirth). The chances of this type of transmission are the same in both vaginal and caesarean births. […]

i-Port: bidding farewell to injections during ovarian stimulation

At Instituto Bernabeu, we are bidding farewell to ovarian stimulation injections during courses of in vitro fertilisation (IVF) treatment. The clinic is launching an innovative device called i-Port Advance™ for self-administration of drugs using a system that is already used by diabetics and which is being put to gynaecological use. By using this device, Instituto Bernabeu is revolutionising the future […]

What became of my embryos? Haven’t I got embryos to freeze?

These are just some of the questions that couples might ask at an important time during their treatment, just before embryo transfer.
In all cases of fertility treatment involving the in vitro fertilisation (IVF) laboratory, it is essential that all couples are given extensive, detailed and personalised information. This means talking about the embryo fertilisation and development processes.
When only a few fertilised oocytes are available as a result of poor ovarian reserve, transfer is carried out on day 2 or 3 of development in around 60% of cases because at this stage we can clearly select the embryos that are suitable for transfer. In around half of these cases it is not possible to cryopreserve embryos for future attempts. […]

A comparison of the phases in IVF and ICSI treatment

1.- Ovarian stimulation in the patient is carried out by administering doses of hormones that stimulate ovarian function with the aim of achieving sufficient oocytes. The doses of the aforementioned hormones are personalised to each patient depending on her ovarian reserve and based on the results of antimullerian hormone levels in a blood test and a follicle count for each ovary using a vaginal ultrasound scan. Controlling each patient’s ovarian response is done over a series of vaginal ultrasound scans (an average of 3) and, in some cases, by checking oestradiol (the hormone produced by the ovary) levels in blood. Once the checks indicate that the ovary is ready, oocyte retrieval is scheduled. This period of ovarian stimulation lasts between 8 and 10 days in most women and does not affect the patient’s daily routine. […]
