Swyer syndrome or pure gonadal dysgenesis

Swyer syndrome is characterised by a discrepancy between the patient’s karyotype and sexual phenotype (gonadal dysgenesis). While patients have a male karyotype (46,XY), they are female in appearance and have normal external genitals. A more exhaustive examination of patients uncovers that they have not entirely developed all secondary sex characteristics.

Traits and symptoms in patients […]

Studies of the cortex and ovarian tissue. Progress in fertility

Although the technique is relatively new (it has evolved significantly over the last 20 years), preservation of the ovarian cortex and posterior transplant in order to recuperate fertility and ovarian function in cancer patients is still an experimental procedure. There is increasingly more evidence regarding the safety of the technique and its evident benefits for […]

Primary ovarian failure and its diagnosis using mass sequencing techniques

Primary ovarian failure (POF) or early menopause is the loss of ovarian function before the age of 40. As a result of this cessation of ovary function, the woman stops having menstruation and her hormonal levels are altered. It’s a common cause of infertility in women, who must resort to assisted reproductive techniques to have […]

Endometrial receptivity analysis (ERA) in patients who require assisted reproduction: is there sufficient evidence?

The ‘implantation window’ defines the period of time during
which the endometrium in the mother’s uterus is in suitable condition for embryo
implantation. Determining when this implantation window occurs is an intense
field of study within the framework of modern assisted reproduction techniques
(ART) and it aims to improve the results our patients obtain.

Endometrial receptivity test

The endometrial receptivity test or […]

GCT: Genetic Compatibility Test to avoid passing hereditary diseases

Our Genetic Compatibility Test (GCT) based on next-generation DNA sequencing analyzes more than  600 or 3000 disorders.

For a person with an hereditary disease, eliminating the chance of passing that disease on to their children becomes a desire as well as the very best gift they could give them. Sometimes, parents don’t even know they are carriers of a disease. A person with an hereditary disease will pass it on to his or her children. Sufferers carry a heavy weight upon their shoulders because they are aware that they will pass on health issues to their children and that this will have a negative impact on their quality of life or lead to premature death. In most cases, we are carriers of one recessive disease or another, but our health is not affected by it. However, there is the possibility that we might pass that disease on to our children.

Testosterone and its effect on Male and female fertility

Testosterone
is an androgenic sex hormone produced primarily in the testes, however the
adrenal glands also secrete small amounts.

It’s
considered the most important androgen hormone in men, as it influences
spermatogenesis, development of secondary traits and sexual differentiation in
the foetal period. However, testosterone is also present in women and has
specific functions.

What’s the testosterone?

Testosterone is a sex steroid
hormone derived from […]
