From now, women who want to conceive but are dependent on egg donation may only receive genetic material until 50 years of age. The rule becomes effective on Thursday (9), when the new resolution of the Federal Council of Medicine (CFM) on assisted reproduction will be published in the Official Gazette The resolution fills the gap does not exist in Brazil, legislation regulating the practice of assisted reproduction.

Before there was an age limit set. The rule is one of the novelties of the third version of the rules governing the procedure. The first standard was established in 1992 and revised only once, in 2010. A committee of experts, which includes gynecologists and geneticists, leaned over the last 12 months to update the document from experiences that have been observed by doctors.

"It is proven that a woman's reproductive age is under 45. We raise for 48 years and after a thorough discussion arrived at age 50. Thereafter there are risks to the woman and the child," said Joseph Gallo Hiran, coordinator Technical Chamber of Assisted Reproduction CFM. After 50 years, increasing cases of hypertension and diabetes in pregnancy. Pregnancy at this age can still lead to the child, low birth weight and premature labor.

Although the definition, experts recognize that may arise cases in which the rule can be bent. "Likewise, in some cases, the doctor may decide not to do the procedure in younger women, considering that there will be able to generate, it can also bend in cases of women over 50 years if they would consider conditions of pregnancy, "explained Carlos Vital, vice president of CFM.

The age of the egg donation was also limited in cases of donation shared, ie, when a woman is trying to conceive donates some of her eggs to an older woman, it does not produce more eggs, in exchange for the cost of the treatment . The doctors decided that the maximum age for donation is 35 years for women and 50 for men who are willing to donate semen.

According to the president of the Brazilian Society of Assisted Reproduction (SBRA), Adelino Amaral, the quality of donor eggs at this age is higher and, therefore, the chances of receiving pregnant increase. "From the age of 35, egg quality decreases and the risk of genetic diseases increases," he explained.

The number of ova and embryos will also only consider the age of the woman who is donating. Ie, the receiver can receive up to four oocyte (female germ cells) and embryos transferred, whereas in women under 35, to receive two embryos, recipients aged between 36 and 39 years can receive up to three embryos and women between 40 and 50 years receive the maximum allowed up to four embryos.

According to experts in the field, the probability of a female becoming pregnant over 40 years is about 10% while up to 35 years, chances are greater than 40%. Considering these scenarios, the restriction reduces the chances of multiple births, ie, more than one child, which could mean risks for older women.

"There is a great demand for women over 45 years old or younger women who do not produce eggs. Has over 5000 women waiting for a procedure such as assisted reproduction, only the public health service of Brasilia," said Amaral.

The full cost of the procedure ranges between £ 15,000 and £ 20,000. In the public health system, the procedure is done in just five units of the federation. And the Federal District, the playback is done in public hospitals in Goiânia, Natal, Recife and in two hospitals in São Paulo.

According to SBRA less than 5% of the in vitro fertilization are made free in the country. "There are some situations in clinics that make a donation today shared in the donor receiving pay nothing and decides to pay the entire treatment," he said. The receiver who bears some or all of the costs of treatment takes the risk of not being able to receive the material, if production is lower.

In cases of shared donation, clinics are required to maintain the confidentiality of the donor, but provide all kinds of information such as height, color of eyes and hair, weight, education to the donor, to try to bring physical appearance and compatibility as the blood, preventing future problems.
