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”.

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?

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 the ‘implantation window’ in fertility treatment?

The ‘implantation window’ is the name we give to the period of time during which the endometrium in the mother’s uterus is in an appropriate state for embryo implantation to take place.

When does the implantation window occurs?

Implantation is a critical and very precise process during which the embryo makes contact with and penetrates the endometrial tissue in the […]

Assisted hatching

Assisted hatching is a technique used in the in vitro fertilisation laboratory that consists of making a small hole in the membrane that surrounds the embryo, the zona pellucida (ZP), with the aim of making it easier to detach from it (which naturally needs to happen) and thus be able to implant in the mother’s […]

Heparin as a Treatment for Repeat Miscarriages or Implantation Failure

Suffering from repeat miscarriages is one of the most painful situations for women trying to have children. This is especially true when these women achieve a pregnancy after using assisted reproduction treatments.

IBgen FIV: genetic test for embryo implantation failure

IBgen RIF analyses the
variants in genes associated with thrombotic risk, immunological factors and
endometrial receptivity and it improves patient prognosis

This achievement emanates from over four years of intense research work. IBGen RIF, a new test that has been developed by Instituto Bernabeu, highlights the causes of implantation failure and recurrent pregnancy loss when the underlying reasons for […]

What can we see in ultrasound scans: follicles or oocytes?

Mistaking ovarian follicles for oocytes is one of the most common errors made by patients.

During ovarian stimulation, whether this is for regulating ovulation for insemination or for in vitro fertilisation, patients are administered different types of medicines depending on each case. However, there is one common aim: predicting and causing ovulation. This can be just once for patients attempting managed sexual intercourse and […]

IBGen RIF: a genetics test for detecting recurrent pregnancy loss and implantation failure

Instituto Bernabeu has managed to determine which genes cause recurrent pregnancy loss and implantation failure. The findings are the result of four years of research and the clinic’s commitment to helping patients who suffer from infertility issues of this kind. These problems are incredibly frustrating for the people who suffer from them. The findings have opened up […]
