FSH

A less invasive, simpler technique: SOFT IVF or MINI IVF

Having a sufficient number of mature egg cells is one of the key steps to obtaining excellent results in a cycle of in vitro fertilisation (IVF). In order to achieve this, the ovaries need to be stimulated and, contrary to what happens during a natural cycle, the ovaries need to simultaneously mature an appropriate number of eggs.
The most commonly used stimulation protocols are based on the use of doses of follicle-stimulating hormone (FSH). These may or may not be administered along with other drugs and vary between 150 and 300 IU/day. The response will be somewhere between 7 and 15 follicles. […]

Premature menopause

We understand the menopause as a complete end to menstruation. It is a retrospective diagnosis (looking back) and, as such, the menopause is said to have taken place when a year has gone by since the last period and, during that time, there have been no instances of menstrual bleeding.
It generally takes place at around 50 years of age and is linked to the number of eggs in the ovary.
Depending on a woman’s age, it can be: […]

FSH hormone levels

Follicle-stimulating hormone (FSH) is produced by the pituitary gland situated at the base of the brain. It is released from this gland into the bloodstream and plays an essential role with regards to the ovaries. Its purpose is to stimulate follicle growth and selection and it also plays a role in maturing the egg which will later be released during ovulation.
In cases of ovarian insufficiency, the pituitary gland attempts to compensate for this by increasing FSH secretion. This happens in a physiological manner during the menopause and, as a result, women going through this stage have FSH levels which are far above those in women of childbearing age.

If abnormally high levels of FSH (>10 lU/L) are detected at a young age, this can be a suggestion of low ovarian reserve which reduces the possibility of getting pregnant naturally. […]

What is the significance of FSH hormone levels in fertility?

Follicle-stimulating hormone (FSH) is essential to reproduction. It is produced by the pituitary gland situated just below the brain (behind the palate) and is released into the bloodstream. The hormone regulates the ovaries and is involved in the processes dealing with the growth and selection of the follicle which will later release the egg during ovulation.
Fluctuations in FSH levels are responsible for menstrual cycles and also for the fact that only one egg is produced during each cycle. It is essential, therefore, that there is constant dialogue between the ovaries and the pituitary gland so that the latter can consistently produce the correct quantity of FSH for a normal cycle.
This permanent exchange means that, in cases of poor ovarian function, the pituitary gland will try to compensate for this situation by increasing FSH excretion levels. It is for this reason that FSH levels in women going through the menopause are 20 times greater than in women whose ovaries are functioning normally. Therefore, when the ovary does not respond correctly, FSH increases significantly and systematically. […]

Poor Ovarian Response: progress in genetics

Ovarian stimulation is key in results obtained as a results of assisted reproduction techniques. Daily clinical practice shows us that ovarian response can vary substantially from one woman to another. With this in mind, we can diagnose a patient as a poor responder when three eggs or less are obtained.
This situation affects more and more women every day. They require specialised healthcare and personalised protocols and, in response to this need, Instituto Bernabeu has a Poor Ovarian Response Unit that deals with multidisciplinary diagnosis and treatment.
For patients under this category, obtaining one or more eggs can mean the difference between failure and pregnancy and this makes any steps taken to increase the number of available eggs absolutely essential. […]

What are follicles? Number, growth and other characteristics

What are ovarian follicles?
To start with, let’s state what follicles are not. Follicles are not oocytes (eggs). Many patients confuse these terms, believing that follicle equals oocyte.
The female gamete is the egg, and the male gamete is the sperm. These are the cells involved in embryos obtained after fertilization. […]

Azoospermia in the IVF lab

Azoospermia is defined as the absence of sperm in the ejaculate, which is generally classified as either obstructive or secretory. In obstructive azoospermia, the sperm cells cannot complete their journey from the testicle to the urethra through the seminal tract; however, the sperm cells are produced in the testicle (spermatogenesis). […]

Anti-Müllerian Hormone (AMH): Know the Age of your Ovaries

Ovarian reserve is a widely used concept in assisted reproduction but patients do not always know the meaning of the results and their clinical implications. A woman’s ovarian reserve refers to the total number of eggs in their ovaries and provides information regarding their reproductive future and their replication potential. […]
