Several courses of unsuccessful fertility treatment. When has the time come to give up?

Whilst the success rates of assisted reproduction treatment are increasingly higher, in a small number of cases, couples who have undergone several courses of in vitro fertilisation without having achieved a viable pregnancy decide to give up treatment for good.

What is estradiol? 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 estradiol in females and testosterone in males. Although it’s true that is produced by both men and women, but at different levels.

Genetic Incompatibility between the couple, does this exist?

is thought that about 20% of the reproductive problems are genetic or chromosomal.
That is why the genetic testing is
now an essential part of the fertility study carried
out on couples who come to our centre for help to have children. Karyotype,
chromosome Y microdeletions or the fragile X chromosome syndrome are tests
usually recommended in the fertility consultation. A positive result in any of
them […]

Why does embryonic arrest sometimes happen during in vitro development?

Many factors can intervene in arrest processes during embryo development which mean cell division is detained and, therefore, it is not possible to implant the embryo in the mother’s uterus and bring about a pregnancy.

In the first instance, the conditions for development are essential.  Embryos that develop in vitro are subjected to a number of artificial […]

What are an embryo’s nutritional requirements prior to transfer to the mother?

During in vitro fertilisation processes, for the first few days of their lives, human embryos have to develop outside the mother’s body in special incubators.  Temperature and pH conditions need to be optimum and embryos also need to have access to all the necessary ingredients in order to feed and, in doing so, meet their […]

Treatment of Klinefelter´s Syndrome and fertility

Klinefelter’s Syndrome is considered the most common chromosomal abnormality  in humans, with an incidence of 1 out of every 500 newborn males. Those affected by this syndrome have an extra X chromosome, which leads to primary testicular failure and therefore infertility and hypoandrogenism.

It is a chromosomal abnormality that only affects men and mainly causes hypogonadism. […]
