The American Society for reproductive medicine, published in the journal fertility and sterility, has reported that the process of freezing and thawing of egg cells is a proven technique to preserve women’s fertility.
Using frozen eggs has almost the same success rate in terms of pregnancies as in vitro fertilisation using fresh eggs. The success rate decreases with age as with other assisted reproduction methods. There was no greater risk of birth defects or chromosomal abnormalities.
Egg freezing can be used for patients who have medical indications for losing their fertility, such as cancer, impending ovarian failure, or even due to genetic reasons.
Other reasons could be failure to receive sufficient sperm on the day of IVF.
Swedish doctors have also performed the world’s first mother to daughter uterus transplants in two women. One of the women had her uterus removed many years ago because of cervical cancer and the other woman was born without a womb.
Children conceived with the help of in-vitro fertilisation (IVF) are more likely to have birth defects, according to the study presented at the American academy of paediatrics conference. However the researchers are not fully with this fact that whether it is the IVF procedure or the infertility itself that is responsible for the heightened risk. Other fertility treatments such as artificial insemination or ovulation were not associated with abnormalities. Birth defects of the eye, heart, reproductive organs as well as urinary systems were more common in children conceived by the method of In Vitro Fertilization (IVF).
