Anti-müllerian hormone (AMH) is no longer a crystal ball

Anti-müllerian hormone (AMH) is used in reproductive medicine as an ovarian reserve marker. This hormone is detected using a simple blood analysis and, in conjunction with a follicle count ultrasound scan on the ovaries, it helps us to predict a patient’s response to stimulation. This is mainly true when patients have a limited prognosis.

In any case, despite how […]

Cryopreservation of the ovarian cortex. What is it? Is it better than freezing ova?

What is cryopreservation of
the ovarian cortex?

Cryopreservation in the field of assisted reproduction treatment has clearly been a revolution on all levels. It has changed strategies in cases in which fertility has been compromised for any one of a number of reasons.

This revolution began with freezing both male and female gametes over the course of the latter half of […]

What is the ‘implantation window’ in fertility treatment?

The ‘implantation window’ is the name we give to the period of time during which the endometrium in the mother’s uterus is in an appropriate state for embryo implantation to take place.

Implantation is a critical and very precise process during which the embryo makes contact with and penetrates the endometrial tissue in the mother, making gestation possible. This […]

What is the corpus luteum?

After ovulation, follicles transform into the corpus luteum or ‘yellow body’. Corpus luteum development depends on the luteinising hormone (LH) surge before ovulation and on the number of receptors for this gonadotropin in the granulosa cells and in the theca cells.  Both types of cells go through significant changes in structure and composition and this turns the walls of the corpus […]

What tests do I need to have before egg donation treatment?

Egg donation has become an option for women who, for whatever reason, can no longer use their own ova. For example, due to poor ovarian reserve, poor oocyte quality and premature menopause.

The process is widely used in Spain. As well as exceeding organ
donations and transplants in number, we also have the largest number of egg
donors in Europe.

It […]

What is oestradiol? What is this sex hormone’s role?

Hormones are messengers that are present in all multicellular organisms – be they animal or plant organisms – that coordinate the functions of each part of that organism.
The sex hormones par excellence are oestradiol in females and testosterone in males. However, the adrenal glands in men and women produce both hormones and they are both necessary for normal development of the two sexes. […]

Have I got poor ovarian response? How should I deal with it?

A patient can be classified as having poor response when the number of oocytes obtained during a cycle of in vitro fertilisation is under what was expected. The criteria generally used to label a patient as a poor responder is when 3 or fewer oocytes are retrieved and she has incredibly low ovarian reserve markers (fundamentally, AMH and AFC). […]

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. […]

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. […]
