Biochemical pregnancy: diagnosis, causes and symptoms

-

A biochemical pregnancy is defined as the early interruption of embryonic development and subsequent lowering of menstruation . It is also known as biochemical abortion or microabortion.

In all cases the sperm gets to fertilize the egg, the embryo is formed and develops until day 6, at which time the embryo implantation takes place in the uterus. It is then that the hormone beta-hCG ( human chorionic gonadotropin ) begins to be synthesized and quantified in a pregnancy test. For this reason, the test is positive even if there is no evolutionary pregnancy.

Biochemical abortion can occur after a natural pregnancy or after in vitro fertilization ( IVF ) treatment. In both cases, the symptoms of the microabortion are the same.

Below you have an index with all the points that we will discuss in this article.

Biochemical pregnancy after an IVF

Many women mistakenly believe that the biochemical pregnancy is a consequence of fertility treatment because it is usually detected in the clinic when doing the blood pregnancy test.

However, the reality is that the rate of biochemical abortion after IVF is approximately 8%.

Therefore, we can conclude that the microabortion occurs naturally with the same frequency as in IVF. What happens is that most of the time goes unnoticed and is confused with a simple menstruation.

It is known that a biochemical pregnancy has taken place when the pregnancy test has been positive and, after a few days, the amount of beta-hCG does not increase exponentially as it should.

Evolution of beta hCG in a biochemical pregnancy

Very low or non-increasing values ??of the beta-hCG hormone usually indicate a biochemical pregnancy.

According to the latest report of the Spanish Fertility Society (SEF), in 2016 were carried out 138,553 cycles of in vitro fertilization (IVF) and 36,463 cycles of artificial insemination (AI), which resulted in a total of 37,503 babies born . This represents an increase of 8% in the use of assisted reproduction techniques with respect to the previous year, which shows that more and more couples need help to have the opportunity to become parents. After a year of sexual intercourse without achieving pregnancy, a couple is considered to have sterility problems, so it is advisable to start doing diagnostic tests and determine the most appropriate assisted reproduction treatment in each case, as we will discuss throughout this post.
