Fertility
There’re many reasons why men and women cannot conceive, even after a previous pregnancy. Either due to dysfunctions in the reproductive system or because the gametes have alterations. Discover the different aspects involved and their treatments.
Embryo transfer on day 4 – why not?
In most laboratories, embryo transfer traditionally takes place on day 2 to 3 of culture, or during blastocyst stage, whilst embryo transfer on day 4 is an alternative that has not commonly been adopted into laboratory practice. When compared with […]
From the very moment when sperm fertilises an ova, a new embryo starts developing and a large number of cell divisions take place. This embryo development is observed in an in vitro fertilisation laboratory up until the […]
Are sterility and infertility the same? No, they are two completely different concepts. Sterility is the inability to conceive whilst infertility is the inability to complete a full term pregnancy and give birth to a healthy child. […]
What does an embryo biopsy entail?
Pre-implantation genetic diagnosis (PGD) is a technique that provides a ‘genetic understanding’ of the embryo before it is transferred to the uterus. Thanks to this technique, we are able to study the embryo’s chromosomal make-up and […]
What impact does cholesterol have on my fertility?
Cholesterol plays an essential role in ensuring that our organism works correctly. Its impact on the heart is still given priority in terms of analysis because of the elevated impact and frequency of diseases of […]
Physiological conditions in embryo culture: reduction of the amount of oxygen in the incubator
Improving embryo culture by mimicking the conditions generated during in vivo culture is a key contributor towards improving success rates in couples who turn to in vitro fertilisation in order to solve their sterility issue. In […]
What became of my embryos? Haven’t I got embryos to freeze?
These are just some of the questions that couples might ask at an important time during their treatment, just before embryo transfer. In all cases of fertility treatment involving the in vitro fertilisation (IVF) laboratory, it is essential that all couples […]
A comparison of the phases in IVF and ICSI treatment
1.- Ovarian stimulation in the patient is carried out by administering doses of hormones that stimulate ovarian function with the aim of achieving sufficient oocytes. The doses of the aforementioned hormones are personalised to each patient […]
Pre-implantation genetic diagnosis (PGD): comprehensive chromosome screening
Pre-implantacional genetic diagnosis (PGD) is a technique used to detect genetic or chromosomal abnormalities and it is performed on the embryo prior to transfer to the mother’s uterus. Its use is recommended in couples where one […]
Thanks to the donor DNA storage bank at Instituto Bernabeu, patients who need to make use of donated gametes for their fertility treatment may, at any time, make a request (further to egg donor consent) for necessary genetics […]
