What is a mature oocyte?

In the ovary, there are structures known as follicles that contain the oocytes or ova. When a patient undergoes in vitro fertilisation (IVF) treatment, ovarian reserve is one of the most relevant pieces of data and it is evaluated by means of an antral follicle count (follicles that are capable of responding to hormones during stimulation cycle). This information is essential in predicting the number of oocytes we will obtain following ovarian stimulation. Following an ultrasound scan and hormone level checks, the gynaecologist decides when ovulation should be triggered in the patient. […]

Fragile X chromosome syndrome and fertility

Fragile X syndrome is one of the most common causes of hereditary intellectual disability.
The gene responsible for the disease is known as FMR1 and it is found in the X sex chromosome. As a result, both the transmission and the severity of the disorder varies in each sex. As a general rule, men are said to suffer from it whilst women are said to transmit it.
There is a repeat region in the FMR1 gene (expansion) and its size determines whether or not the individual has the disorder or not, as indicated below. […]

Antiphospholipid Syndrome: What is it? How does it affect pregnancy?

Antibodies are proteins produced by the immune system of our organism to combat possible infections of viral or bacterial origin. In some diseases, the immune system produces antibodies that, erroneously, attack the tissues of our own body. The result of this attack is the appearance of what are known as autoimmune diseases. […]

Sperm capacitation

The spermatozoa in ejaculate need to have gone through a process known as sperm capacitation in order to obtain the ability to fertilise. This happens naturally in the female reproductive system and techniques in order to make it happen in the laboratory have been undergoing development for many years. […]

How long should I wait before beginning a new course of treatment following unsuccessful IVF?

In vitro fertilisation (IVF) treatment is not always successful. The reasons for this can include the cycle being cancelled during the stimulation phase or during the fertilisation and embryo development processes in the laboratory; or embryo implantation failing to take place following transfer and a negative pregnancy test result. […]

10 things you should know if you want to freeze your eggs

1 . Does it hurt?
Egg Retrieval is painless. It is carried out by means of a simple vaginal procedure, and the patient is lightly sedated.
2. What’s the right age for preserving my eggs?
Whilst there is no minimum nor maximum age, it is advisable to undergo the procedure before 35 years of age in order to obtain a sufficient number of good quality eggs because, from 35 years of age onwards, there tends to be a decrease in both their quantity and quality. […]

Can we have a healthy child if we have hepatitis?

Hepatitis is severe or chronic inflammation of the liver.
There are several possible causes including infections (viral, bacterial or parasitic).
The most common cause is a viral infection and, within these, hepatitis B (HBV) and hepatitis C (HCV) viruses are of particular relevance. It is possible to get infected as a result of contact in blood and contaminated objects (unsterilised surgical material, syringes or needles), due to sexual transmission through mucous membranes and so-called vertical transmission (transmission from mother to child, particularly during childbirth). The chances of this type of transmission are the same in both vaginal and caesarean births. […]
