What is the Low Ovarian Response?
Controlled ovarian stimulation is a key part in the in vitro fecundation treatment, as the eggs number retrieved is directly related to the possibility of achieving pregnancy. Despite the continuous advances in the assisted reproduction techniques, the low response to the ovarian stimulation still a challenge in the everyday clinical […]
One of the
basic studies done to determine the male’s sperm quality is the seminogramme ,
also known as spermiogramme. We would need a sperm sample to carry it out (see how
to take the sample correctly). Sperm is analysed from macroscope and
microscope point of view.
What is the seminogramme?
The most relevant parameters of the study are threefold:
Sperm countSperm […]
During in vitro fertilisation processes, for the first few days of their lives, human embryos have to develop outside the mother’s body in special incubators. Temperature and pH conditions need to be optimum and embryos also need to have access to all the necessary ingredients in order to feed and, in doing so, meet their […]
Klinefelter’s Syndrome is considered the most common chromosomal abnormality in humans, with an incidence of 1 out of every 500 newborn males. Those affected by this syndrome have an extra X chromosome, which leads to primary testicular failure and therefore infertility and hypoandrogenism.
It is a chromosomal abnormality that only affects men and mainly causes hypogonadism. […]
Currently there are two main techniques used to achieve Assisted Reproduction IVF. These two techniques are conventional in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI).
In IVF, the previously capacitated male sperm are deposited together with the oocytes of women in fertilization medium in order to achieve fertilization as similar as possible to that […]
Pre-implantation genetic diagnosis (PGD) consists of studying chromosomal abnormalities and genetic abnormalities in the embryo prior to transfer to the mother. Its purpose is to ensure that children are healthy and put an end to the transmission of a specific condition.
There are two types of PGD: the PGD aimed at selecting embryos that are free of a genetic disorder affecting a […]
Infertility is an issue which has significant emotionally taxing consequences for couples. The inability to fulfil such an important part of personal development as having children directly affects all aspects of the patients’ lives.
Psychological impact
The individual’s core is affected and there is a breakdown in important matters such as self-confidence, future plans, life as a […]
Over the last few years, there has been growing scientific interest in
understanding the relationship between environmental and occupational exposure
to toxic substances and contaminants and a variety of human health issues, in
addition to the impact that these products may have on a couple’s ability to
have children.
Contamination
A presence in
the environment of damaging elements (be they chemical, […]
Now what? Why can’t I get pregnant?
These are undoubtedly the first two questions that come to mind after being evaluated for a fertility problem and the doctor tells you that there’s no known cause that explains why you can’t get pregnant.
Nowadays, basic sterility studies are unable to detect the exact cause of over 25% of all cases, which doesn’t mean that it can’t be diagnosed with specific tests or that a case with an unknown cause can’t be properly treated.
[…]
One of the options for patients undergoing In Vitro Fertilization (IVF) techniques with remaining embryos, meaning high quality embryos that can be cryopreserved for the future, is to donate these embryos to other couples for reproductive purposes. In most cases, these embryos come from couples that have gone through double donation treatments (egg and sperm), […]
