One of the most exciting times during a treatment of assisted reproductive is the Embryo Transfer. After carrying out all the laboratory processes, microinjection (ICSI) or insemination (IVF) and embryo culture, among others, it is time to transfer the selected embryo.
However at times it is not possible to transfer the
embryo and we must cancel or […]
Hereditary disorders (disorders that are transmitted from parents to offspring) include a group of disorders known as autosomal recessive disorders. Disorders of this kind are uncommon. However, they do tend to be rather serious. Indeed, they are the reason why a significant number of children end up in hospital or even die. In recessive disorders, […]
Patients
undergoing an in vitro fertilization treatment usually ask if are able
to distinguish between male and female embryos while observing them in the lab.
Can we know the embryo
gender before implantation in the mother’s uterus?
Although
the embryo’s gender is established at the time of the egg and sperm union, is
not until week 5, approximately, when the embryo develops […]
Women with reduced ovarian reserves (low antral follicle count and/ or low Anti Mullerian hormone levels) have a higher risk of poor response to hormone stimulation and low pregnancy rates during IVF treatment.
What is the DHEA and what is it for?
According to some research, the steroid hormone DHEA (Dehydroepiandrosterone) could increase conception rates during […]
The retrieval of the oocytes from the
follicular fluid marks the beginning of a series of events the purpose of which
is to achieve a pregnancy and a later birth of a healthy baby. This is also the
beginning of the technical work of the IVF laboratory embryologists. Before
every cycle, we thoroughly study each clinical history and prepare […]
Fertilization is a key step in sexual reproduction, is the union between a healthy
egg and sperm, giving place to a zygote: the first cell of a living person.
In the assisted reproduction lab, fertilization is in vitro. Embryologist’s favour the gametes encounter and, classify the obtained embryos, which later, in the laboratory, will develop as […]
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 […]
As a result of a number of television programmes, as well as articles in newspapers and online, it has now become public knowledge that what we commonly know as artificial insemination at home is becoming an increasingly common practice.
The term could well be labelled incorrect or even deceptive if we take into account that insemination […]
The human genome consists of 46 chromosomes: 23 of these are inherited from our father and the other 23 are inherited from our mother. Our organism’s entire genetic make-up is stored in these chromosomes. The 23 pairs are organised as follows: 22 pairs, known as autosomes, and one pair of sex chromosomes (X and Y) which […]
One of the main limitations of assisted reproduction techniques are its embryo implantation failure rates. The implantation rate is the embryo’s ability to implant in the mother’s uterus. In other words, not all embryos are able to give rise to a pregnancy. Some have a greater chance of doing so than others. If it were possible to select […]
