The maximum fertility of women is between 18 and 30 years. You can always vary depending on the case, but age is the main prognostic factor egg quality.

Therefore, after 30 years fertility begins to decline in a subtle way up to 35 years. At age 35 the oocyte quality, and therefore fertility begins to decrease more sharply.

Between 37 and 40 years loss of fertility and occurs exponentially, while already from 40 years fertility is usually quite compromised.

The ideal is to have a pregnancy at an early age. That is, the younger the better woman, thus reducing the risks.


Differences between pregnancy at 20 and 40

All risks for both the woman and the fetus, increase with age:

On the one hand, the risk to the baby present genetic defects such as Down syndrome, gestational hypertension or growth retardation increases with gestational age. Similarly, they increase cesarean section and perinatal morbidity and mortality in general.

This does not necessarily mean that obstetric and neonatal care today can not be achieved pregnancy and healthy newborn at home, but should risk a pregnancy that happens past 40 years.


Egg freezing, how to preserve fertility

Egg freezing is emerging as a possible way to delay motherhood.

Indications for egg freezing can be very diverse, but currently the most common cause is the social or medical cause, which is due to sociocultural trends of women that leads to delay motherhood, such as study, work or economic reasons.

The other indication is the cause cancer, such as breast cancer or hematologic diseases such as lymphoma or leukemia. During the illness, patients receive chemotherapy treatments also damage the ovaries, so that healthy eggs are frozen before treatment. After overcoming the disease, she can be a mother using eggs that have been frozen.

Another frequent indications is increasing and patients are suffering from ovarian endometriosis. Endometriosis is associated with infertility, and patients who suffer at risk of losing their fertility, so egg freezing is an ideal indication in these cases to preserve fertility in this group of women.


Age for egg freezing mother

By consensus, the age limit allowed for recourse to these techniques is 50 years. Thus, fertility clinics and discarded pregnancy at this age, as it is considered that the risks far outweigh the benefits.


Egg freezing techniques

Vitrification freezing technique is the most currently used. Is a system of quick freezing solidifying the cell, thus preventing ice crystals from forming inside. With vitrification, results in egg freezing have radically changed compared to previous techniques and currently the survival of the egg vitrification and devitrification is 90%.


Risks of egg freezing

No study to date has found increased risks in egg freezing, with respect to pregnancy by conventional IVF or spontaneous pregnancy or for the mother or the fetus.
