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 […]

Why hasn’t my assisted reproduction treatment worked?

The miracle of conception involves an intimate union between the ova and spermatozoon, appropriate evolution of the fertilised embryo and, furthermore, an ideal environment inside the uterus so that implantation can take place. Whilst this process might seem simple, it is much more complex than we might think, particularly in human beings. Only 30% of our conceptions end in […]

What is orchitis? What impact does it have on male fertility?

Mumps rubalavirus leads to an illness during infancy that is commonly known as mumps and that can, in some cases, affect male fertility and lead to male fertility issues.

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 […]

Can patients manage embryo and gamete transportation?

Whilst it is not part of the day-to-day routine at reproductive
medicine clinics, it is now increasingly common to have to transport biological
samples (oocytes, semen or embryos) from one clinic to another and even from
one country to another.

There can be several reasons for this such as the following:

– The
couple wishes to continue their treatment in a […]

Embryonic development: the embryo on day 1 (D1)

When an oocyte is in an optimum state of maturation, ovulation takes place. This is known as day 0 of development (D0) and fertilisation by a competent spermatozoon must take place during this period.

When the oocyte is fertilised, it is then known as a zygote and
we are now on D1 of development. Certain characteristics and essential
structures need […]

Obesity and fertility

The extent of the issue
Obesity is a public health issue both in the general population and in women of childbearing age. The figures are a proof of this and, far from improving, the problem has been getting progressively worse over the last few years.
Maternal obesity in the United States of America was calculated to be 7% in 1980 and had risen up to 24% by 1999. If we take into account both obesity and excess weight, the available data indicates that the figures were 37.1% in 1999 and 40.5% in 2003.
The NHANES (National Health and Nutrition Examination Survey) reveals obesity figures (BMI or body mass index ≥ 30 kg/m2) in women of reproductive age (20 to 39 years of age) of 31.9%.
In other words, one in every three women of a fertile age is obese. […]

What is the impact of obesity on male fertility?

Obesity, when understood as a body mass index (BMI) in excess of 30kg/m2, is associated with numerous health issues including hypertension, diabetes, hypercholesterolemia and so on. It also affects fertility. In women, the impact of obesity is very clear. It generates hormonal abnormalities that have a direct impact on a woman’s ability to reproduce. As a result, obesity in women has been the subject of numerous studies and there are a large number of publications on the matter. […]
