Fertility Treatment Medication

There are many drugs that are used when a couple undergoes a fertility treatment (IVF, insemination, egg donation, etc.). Some are very simple to use and have virtually no side effects and others are more complex and have greater side effects.

We shall now discuss the most commonly used drugs, what they are and their side […]

Anti-Müllerian Hormone (AMH): Know the age of your ovary

What is Anti-Müllerian hormone?

It is a protein that plays a key role in sexual
differentiation during the foetal stage. In males, it is produced by a specific
type of testicular cell (Sertoli cells). In the presence of this hormone, the
development of the male phenotype begins. However, when the Anti-Müllerian hormone
is absent, the differentiation of certain female structures […]

Endometriosis and Fertility

What is Endometriosis?

Endometriosis is a benign, inflammatory, chronic and incurable disease that affects the health and fertility of nearly 180 million women worldwide. To get a global idea, it affects 1 in 10 women of reproductive age. Although it is an increasingly known disease  in our society, there is still a large part of the […]

Normal and abnormal embryo division

For as long as we can remember, we assume that we belong to certain standards. These standards are set based on the average population, just as children in pediatric check-ups are assessed by a percentile of height and weight. As adults we are assessed by our body mass index. In both cases, we try to reach an “average” rate.

What do we consider average?

This also happens at the embryonic stage. The process of embryo division observation is established to assess whether or not embryos are normal. This observation should be performed at specific times, so that each embryo is observed and evaluated daily.

Difference between identical and fraternal twins

Before establishing the biological origin differences between identical and fraternal twins, let’s make a quick note on the etymology of both words.

Etymologically both terms have the same origin (Latin gemellicium) and were used interchangeably to refer to children born in the same delivery. The only difference was the use of the term fraternal twin in the popular speech twin and identical twin in the cultivated speech. However, the semantic evolution of both words has been accompanied by the numerous advances in the field of genetics and knowledge of the development of the human embryo. In fact, since they differ in the latest edition of the dictionary of the RAE:

Definition of fraternal and identical twin

What is a Chemical Pregnancy?

 There are times when we give patients the results of  in vitro fertilization, we tell them that the test is positive, but that it is not good news, and that the chances that it involves into an ongoing pregnancy are slim. It is a very difficult situation, emotionally, since it is very hard for patients to understand what has happened. If it really is positive. Then why isn’t that good news? If it’s not good news, then why do I still have to take medication?

Anembryonic gestation

The anembryonic pregnancy or “blighted ovum” is a specific type of miscarriage in which the fertilized egg implants in the uterus but the embryo does not develop.

It is a relatively common problem: 10-15% of clinically detected pregnancies are lost spontaneously and one third of them are blighted ovum.

What causes anembryonic pregnancy

After fertilization, that is, after the union of sperm and egg, begin a series of cell divisions that lead to the formation of the gestational sac  surrounded by a “shell” or cover called trophoblast (which is the one that will lead to future placenta). Inside the gestational sac the embryo will develop. In the case of anembryonic pregnancy the gestational sac is formed with the trophoblastic cover. But the embryo is not displayed because it has stopped developing at a very early stage, before reaching a millimeter in size, so it cannot be detected with an ultrasound.

Why aren’t all embryos obtained from an IVF cycle suitable for freezing?

Why aren’t all embryos obtained from an IVF cycle suitable for freezing?

Today, in In Vitro Fertilization treatments, it is not extraordinary to find ourselves on the day of embryo transfer with a high number of good quality embryos. For a fresh transfer we shall be electing the embryo or embryos that morphologically and kinetically demonstrate greater development and ‘the other’ good quality ones can be cryopreserved.

BETA pregnancy confirmation after IVF or other reproductive techniques

What is a Beta: B-hCG pregnancy test ?

The determination of the levels of the hormone beta-hCG in blood. The hormone produces the embryo and passes to the mother via the placenta. This is the first measurable sign of embryo implantation.
