                                               PRE-IMPLANTATION GENETIC DIAGNOSIS Preimplantation genetic testing is a technique used to identify genetic defects in embryos created through in vitro fertilization (IVF) before pregnancy. Preimplantation genetic diagnosis (PGD) refers specifically to when one or both genetic parents has a known genetic abnormality and testing is performed on an embryo to determine if it also carries a genetic abnormality. In contrast, preimplantation genetic screening (PGS) refers to techniques where embryos from presumed chromosomally normal genetic parents are screened for aneuploidy. Because only unaffected embryos are transferred to the uterus for implantation, preimplantation genetic testing provides an alternative to current postconception diagnostic procedures (ie, amniocentesis or chorionic villus sampling), which are fre...

                                                                  POOR OVARIAN RESERVE Fertility peaks before the age of thirty and thereafter, it is believed to decline gradually. Poor ovarian reserve (POR) is an important limiting factor for the success of any treatment modality for infertility. It indicates a reduction in quantity and quality of oocytes in women of reproductive age group. A woman’s prime reproductive years are typically between her late teens and late 20s. As they move past that window, the number of eggs in her reserve naturally goes down. So does their quality since the eggs they are more likely to have abnormal chromosomes that make conception harder. As a result, the woman’s ability to get pregnant will start to decrease steadily after age 30. By age 45, it’s unlikely that most women will get p...
