The karyotype is the number of chromosomes in metaphase that we have. Chromosome count and therefore karyotype are characteristic to each species. Human beings have 46 chromosomes (23 pairs) in the nucleus of each cell in their body. These 23 pairs are organised into 22 pairs termed autosomes and one pair of sex chromosomes (X and Y) that differentiates both sexes (men XY and women XX). […]
From January 2016, Instituto Bernabeu will work on a clinical trial (free to participating patients) with the aim of evaluating the efficiency of a line of treatment in patients with poor response to ovarian stimulation.
The research, which has already been approved by the Spanish Drug Agency and has been published in the USA National Health Institute register, involves comparing ovarian response to two different stimulation protocols. One is conventional with drug administration starting at the beginning of the cycle. The other, new procedure carries out stimulation once it has been confirmed that the patient is ovulating. […]
In modern society, the increasing demand for assisted reproduction techniques from single women and same-sex couples has become a reality. From the perspective of reproduction, women only need to receive the male gamete (sperm). For years, these couples have solved the problem in ways that have not always been medically or legally safe and have had to face the possibility of infectious diseases and paternity suits.
Today, these inconveniencies are solved in assisted reproduction centres, where procedures that meet their demands and offer them a solid and safe foundation are regularly performed.
Thanks to Assisted Reproduction Techniques (ART), Reproductive Medicine enables us to distinguish the fact of reproduction from the act of intercourse between two people. Several options for motherhood are offered to both single women and […]
In contrast with the old-fashioned belief that reproduction issues are a female thing, current figures are clear: 47% of infertility cases in a couple are down to an issue with the man. Therefore, when a couple has infertility issues and they seek the help of a clinic specialising in assisted reproduction, the tests and analyses are carried out on both members of the couple. This practice of looking into both the female factor and the male factor is now common and carried out by all experts in the field, but there is still a lack of understanding of the fertility issues which men can have. What are they? What solutions do leading assisted reproduction clinics offer nowadays?
The most common issues amongst men are “changes in the sperm count with no apparent cause”, explains Instituto Bernabeu in Alicante. That is, a low number of sperm, poor sperm mobility or abnormal morphology. Additionally, there may be more concrete and identifiable reasons for changes in sperm such as obstruction issues, infection, diseases or genetic reasons which impede egg fertilisation or which affect embryo quality.

Couples who are seeking pregnancy and have not managed to succeed for some time must surely have asked themselves this question.
These days, reproductive problems are more common than we may think. Consulting for them should not cause any fear, embarrassment or stress. Furthermore, in many cases the first consultation will help to correct minor abnormalities and facilitate pregnancy in a short period of time and in the simplest way conceivable.
Whatever the case, the advisory guidelines below are offered to help the process of deciding when to schedule an appointment with a specialist in Reproductive Medicine:
Age: The relationship of fertility with age has been made abundantly clear. As a consequence, the older the age, the shorter we should wait to schedule a fertility appointment. For example, from age 37, seeking pregnancy for just a few months would be enough to perform an initial assessment. In general, women who are younger than 30 may wait about a year for pregnancy to occur spontaneously.
Assisted Human Reproduction is undoubtedly an area with ethical and moral implications. There are common issues that arise with the generation of new embryos when a couple undergoes ART and with transfers of previously frozen embryos. Some of the most frequent issues are: embryo manipulation and genetic diagnosis; the use of donor gametes and the possible coexistence of their legal children with the biological ones in the future; the option of discarding embryos by parents for no other purpose when they don’t wish to donate them to other couples with reproductive problems or for research purposes; the age of women accessing ART, along with a long list of legal, ethical and moral issues pertinent to each assisted reproduction centre. […]
Couples who do not get pregnant following in vitro fertilisation treatment and couples who experience pregnancy loss during the early stages of pregnancy, require interdisciplinary guidance in order to diagnose and treat their particular reproductive issue.
From a genetic point of view, patients of this kind are more likely to generate embryos with chromosome abnormalities. Pre-implantation […]
Preimplantation Genetic Diagnosis (PGD) is a new technique used in Reproductive Medicine and is one of the main sources of innovation and research. PGD allows embryos to be selected from assisted reproduction cycles and tested for certain genetic or chromosomal abnormalitybefore being transferred to the womb.
For 21 years, egg donation has been a treatment that Instituto Bernabeu offers to women who need it, which has made it a European reference point for egg donation.
It is the reproductive technique with the highest pregnancy rates, over 60% per cycle. At IB, the overall pregnancy rate after three cycles of treatment is over 90%. […]
