Ectopic pregnancy

What is an ectopic pregnancy?

Any
pregnancy implanted outside the endometrial cavity is called an ectopic
pregnancy. It is a condition that occurs in 1-2% of all pregnancies. Despite
the progress in its treatment and early diagnosis, its appearance and possible

Reproductive Immunology: What it is, causes, treatment and how it can affect the achievement of pregnancy

Pregnancy is a physiological state that conceptually challenges the foundations of immunology. While pregnant, the mother has to coexist with a being different from herself in at least half of its genetic origin. The, so-called, “tolerating the intruder” contradicts the principle of how the immune system functions: “tolerating one’s own and rejecting that of others”.

Types […]

Bleeding with pregnancy loss in the first trimester of pregnancy

What
is the first trimester bleeding?

The
appearance of bleeding through the vagina at any moment of the pregnancy is
called pregnancy metrorrhagia or obstetric metrorrhagia.

It
is always a sign of alarm and always needs medical assessment.

It
can appear at any week of the pregnancy. We will now speak about bleeding or metrorrhagia with pregnancy

Endometrial polyps: what are they, how are they formed and what are the symptoms and treatment?

What are endometrial or uterine polyps?

Endometrial polyps are cell formations that project from the
endometrial cavity.

They are a common gynaecological pathology experienced by 20%
of women. They appear most commonly in women aged between 40 and 65.
However, women of all ages can have them.

They contain endometrial glands, stroma and blood vessels. They
attach to the uterine wall across […]

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

Embryo implantation bleeding

What is implantation bleeding?

Implantation is the process
through which an embryo starts its development in the maternal uterus and it
sometimes causes a bleeding. The implantation is caused by the growth of the
embryo -which is already in blastocyst stage
by the moment it arrives to the endometrium- enabling it to implant in the
walls of the uterus, and thus, […]

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.

What is Preimplantation Genetic Diagnosis (PGD)? Is PGD indicated in all patients?

Preimplantation genetic diagnosis (PGD) is a very useful tool in Assisted Reproduction for the genetic selection of embryos prior to their transfer to the maternal uterus. It allows the selection of healthy embryos for a large number of diseases and alterations, thus avoiding the transmission of hereditary diseases and the transfer of embryos that would […]
