The health emergency generated as a result of the impact of Covid-19 has caused an unprecedented total stop to activity in the field of assisted reproduction, following the safety recommendations of the main scientific societies. Although there is currently no evidence that the virus can be isolated in gametes and embryos, preventing pregnancy is suggested […]
An ectopic pregnancy is a pregnancy that occurs outside the uterus. The most common place for this to happen is in the Fallopian tubes and it impedes progress of the pregnancy.
In vitro fertilisation was traditionally believed to potentially increase the risk of this pathology.
A study published in the Fertility and Sterility journal covered this subject in detail and, further […]
Does ovarian stimulation for in vitro fertilisation treatment increase the risk of gynaecological cancer?
One of the common concerns that women who are about to embark on in vitro fertilisation treatment have is the hypothetical risk of getting gynaecological cancer as a side effect of hormone stimulation.
Since in vitro fertilisation began, a number of different studies have been published that indicate that the risk of getting breast cancer, cancer of the ovaries, the […]

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 […]
The World Health Organization (WHO) indicates that a man has hypospermia when the semen sample he produces when he ejaculates is below 1.5 mL. A semen analysis needs to be performed in order to obtain a diagnosis. This test measures different semen parameters such as the volume of the ejaculate, the number of spermatozoa, sperm mobility and so on.
In order […]
Ova and spermatozoa are needed in order to be able to perform in vitro fertilisation treatment. They are taken to the in vitro fertilisation laboratory so that, once they have been appropriately prepared, they can be joined together and fertilise.
Unfortunately, biology is not an exact science and the uniting a spermatozoon and an ovum does not always create an […]
A person’s blood group is determined by a number of proteins
that are found on the surface of red blood cells. There are 4 main blood groups
depending on if these proteins are present or not: A, B, AB and 0. An
additional protein known as factor Rh has also been located on the surface. If
a person has […]
Mayer-Rokitansky-Küster-Hauser syndrome – or simply MRKH syndrome – is a congenital disorder (birth defect), the main characteristic of which is that the women who suffer from it do not have a uterus.
The cause of this infrequent condition (1 in 5,000 female births) is an abnormality during development of the internal genitalia during the embryo/foetus stage. As well as an […]
Culture mediums used during embryo development in in vitro fertilisation (IVF) laboratories are crucial to the exit of assisted reproduction treatment of any kind. Culture mediums have the mission of reproducing the physiological conditions inside the female reproductive system as closely as possible, embracing fertilisation up until embryo implantation in the endometrium.
In order for implantation to take place during […]
When in vitro fertilisation treatment commences, one of the aims is to try and achieve an appropriate number of good quality embryos in the laboratory so that the best ones can be selected and transferred. Whilst the Spanish law on assisted reproduction (Law 14/2006) permits transfer of a maximum of 3 embryos per cycle, progress in techniques has meant that […]
