Ms Vanneste and her team studied each cell from 23 three or four day-old IVF embryos from young (less than 35 years old), fertile couples who had asked for preimplantation genetic diagnosis (PGD). PGD is carried out where one or both parents have a known genetic abnormality, in this case an X-linked disorder or the microdeletions (loss of a tiny piece of a chromosome) that can cause such disorders as the cancer predisposition syndrome neurofibromatosis type 1.
For the first time, researchers have been able to identify genetic predictors of the potential success or failure of IVF treatment in blood. Dr. Cathy Allen, from the Rotunda Hospital, Dublin, Ireland, told the 25th annual conference of the European Society of Human Reproduction and Embryology today (Wednesday 1 July) that her research would help understand why IVF works for some patients but not for others.
Dutch researchers find first evidence that female human embryos adjust the balance of X chromosomes before implantation in the womb. Results have implications for in vitro fertilisation and embryonic stem cell research
A very common question of perimenopausal women is whether or not they are still able to get pregnant, and this inquiry may originate from one of two concerns. Some women in the perimenopausal range may still want to conceive, either to start a family or to add to an existing one, and are seeking information to help with that decision.
The tragic events of September 11 have, to put it mildly, thrown many people off balance. On a somewhat secondary scale, our Society was affected. The 5th Regional Meeting of ISGE in conjunction with the 2nd Brazilian Congress of Gynecologic Endoscopy took place on September 12-15, 2001.
Advances in technologies have allowed conduct of many procedures by laparoscopy and hysteroscopy. These are the essence of our specialty. Most new technologies foster improved performance. In business term, they are called sustaining technologies. In fact, most technological advances in an industry are sustaining in nature.
The female reproductive function depends on the healthy ovaries (primary reproductive organ) and genital tract organs. Infertility is one of the main gynecological problems which affect between 10-15% of females in the reproductive age.
This is a term that includes several conditions that are associated with the results of a pregnancy. The conditions are molar pregnancy, invasive mole, metastatic mole and gestational choriocarcinoma(korio carcinoma). These are cancers and cancer like conditions of placental elements. The concept is so far beyond most people's experience, that unless they have been to medical school they will never have heard of it. It is not uncommon.
Although sperm and embryos (fertilized eggs) have been successfully frozen and subsequently thawed to create healthy children for decades, it is only recently that successful human egg freezing has become a reality.
To review utilisation of elective embryo cryopreservation in the expectant management of patients at risk for developing ovarian hyperstimulation syndrome (OHSS), and report on reproductive outcome following transfer of thawed embryos.
