Multiple pregnancy after in-vitro fertilization and embryo transfer: report of a quadruplet pregnancy and delivery.
The first baby from in-vitro fertilization (IVF) was born in England in 1978 as a result of retrieval of a single preovulatory oocyte in the course of a natural cycle (Steptoe and Edwards, 1978). At present most programmes of IVF throughout the world do not use natural cycles producing only one oocyte, but rather multiple oocyte cycles produced by clomiphene citrate (CC), human menopausal gonadotrophin (HMG), or pure follicle stimulating hormone (FSH), either separately or in combination, sequentially or concomitantly, for the induction of multiple follicular maturation.
