Infants conceived by in vitro fertilization may have a higher risk of developing cancer

Infants conceived by in vitro fertilization may have a higher risk of developing cancer

The onset of cancer, such as leukemia, eye and nervous system cancer, is relatively rare in childhood, however, the German study found that the probability can increase from mild to moderate, reaching 34% in infants born with artificial insemination.

For these findings, the researchers evaluated more than 26,000 children born through of artificial insemination from 1982 to 2005 and also used another Swedish study that looked at 17,000 children. In addition, variables such as maternal age, number of pregnancies, previous abortions, body mass index, among others were considered.

Considering all types of cancer found, infants with artificial insemination had about 40% more likely to develop a tumor. However, the study found a relationship that is not considered cause and effect. The main author of the study, Brengt Kallen points out that the high risk may not be caused by in vitro fertilization itself, but may be more related to infertility and factors such as complications in the newborn.

The researcher pointed out that it is necessary to be cautious with the finding since previous studies used to find an increased risk in children conceived by in vitro fertilization of health complications in the beginning of the life and congenital defects. But more recent research has shown that the risk of these babies' problems is not much different than those born normally.

Kallen points out that the importance of their study is that it serves as a warning for parents who are considering or considering in vitro fertilization know that it has complications, albeit mildly moderate. However, he says he does not find it necessary for people to stop using in vitro fertilization.

Choosing the method

Nowadays no one needs to suffer from infertility problems. Many techniques available on the market today can help the couple to have the expected baby. Joji Ueno's Human Reproduction Specialist, Joji Ueno, outlines the main methods used for those who intend to have a child:

- Insemination with partner's semen: in cases of temporary or permanent absence of the partner, low sexual frequency and erectile dysfunction ;

- Programs of in vitro fertilization and micromanipulation of gametes: it allows inseminations programmed in the same cycle of treatment.

- Cryopreservation of semen for individuals who wish to undergo vasectomy, in order to preserve future fertility;

- Sperm cryopreservation for individuals who wish to undergo vasectomy, in order to preserve future fertility; Cryopreservation of spermatozoa obtained during microsurgical reconstruction of the reproductive system, such as vasectomy reversal;

- Cryopreservation of spermatozoa obtained by surgical techniques of the epididymis or testicular parenchyma for use in micromanipulation of gametes is also applied: ICSI

- Intracytoplasmic sperm injection;

- Cryopreservation of semen from individuals working in high-risk occupations such as: deep-sea divers, chemical industries, exposure to pesticides and exposure to ionizing radiations.

Infertility is a mourning to be worked out. or acceptance of this condition, there remains the feeling of impotence before conception. Accepting the limitation of the body to conceive naturally is the first step in diminishing one's own prejudice against treatments involving assisted human reproduction techniques, "says Joji Ueno.

Narrow hip bone can prevent normal birth?

Narrow hip bone can prevent normal birth?

From the obstetric point of view, the knowledge of the bony pelvis (PO), also called the bone or hip basin is indispensable, since it is through it that the fetus passes to be born during childbirth. It consists of four bones: the two iliac bones, the sacrum and the coccyx. These four bones form a "ring" called the pelvic girdle and have two planes: superior or large pelvis (also called "false pelvis") and the lower or small pelvis (also called "true pelvis").
