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.

What is oestradiol? What is this sex hormone’s role?

Hormones are messengers that are present in all multicellular organisms – be they animal or plant organisms – that coordinate the functions of each part of that organism.
The sex hormones par excellence are oestradiol in females and testosterone in males. However, the adrenal glands in men and women produce both hormones and they are both necessary for normal development of the two sexes. […]

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. […]

Is ovary size important?

As is the case with all the organs in our bodies, over our lifetime, ovaries go through changes that affect not only their size but also how they perform. The ovaries are situated between the uterus and the fallopian tubes. They are essential to reproduction and, therefore, to the survival of the human race.
The ovaries begin to develop when female embryos are around 8 weeks old and during pregnancy they undergo a number of changes that prepare them for their role in reproduction when a woman is in her childbearing years. […]

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? […]

Premature menopause

We understand the menopause as a complete end to menstruation. It is a retrospective diagnosis (looking back) and, as such, the menopause is said to have taken place when a year has gone by since the last period and, during that time, there have been no instances of menstrual bleeding.
It generally takes place at around 50 years of age and is linked to the number of eggs in the ovary.
Depending on a woman’s age, it can be: […]

What is the significance of FSH hormone levels in fertility?

Follicle-stimulating hormone (FSH) is essential to reproduction. It is produced by the pituitary gland situated just below the brain (behind the palate) and is released into the bloodstream. The hormone regulates the ovaries and is involved in the processes dealing with the growth and selection of the follicle which will later release the egg during ovulation.
Fluctuations in FSH levels are responsible for menstrual cycles and also for the fact that only one egg is produced during each cycle. It is essential, therefore, that there is constant dialogue between the ovaries and the pituitary gland so that the latter can consistently produce the correct quantity of FSH for a normal cycle.
This permanent exchange means that, in cases of poor ovarian function, the pituitary gland will try to compensate for this situation by increasing FSH excretion levels. It is for this reason that FSH levels in women going through the menopause are 20 times greater than in women whose ovaries are functioning normally. Therefore, when the ovary does not respond correctly, FSH increases significantly and systematically. […]

Genetics in premature ovarian failure and menopause

Oocytes are the female gametes, cells that, upon being fertilised by the sperm, will produce an embryo. In humans, the number of oocytes that females have throughout their lives is not unlimited; they are born instead with a limited number. These oocytes gradually run out in each menstruation until their supply becomes completely exhausted at menopause.
It is said that women suffer from premature ovarian failure when menstruation ceases because the oocyte supply has become exhausted at an earlier age than the age when the natural decline of ovarian function occurs (at 50, approximately). In cases where oocytes are still produced in women suffering from premature ovarian failure, they do not respond satisfactorily to the hormones responsible for their development and maturation.
Premature ovarian failure may have important consequences for women:

Obviously, in their fertility: These women cannot conceive naturally and require assisted reproduction techniques in order to bear offspring. These patients also have a high risk that their oocytes will not respond to the In Vitro Fertilisation cycle, thus putting the success of the treatment in danger.
On the other hand, the absence of female hormones due to low ovarian activity has serious consequences for health, mainly in cases of cardiovascular disease and osteoporosis.
