IVF is a method of assisted reproduction in which the man's sperm and the women's egg are combined in a laboratory dish, where fertilization occurs. The resulting pre-embryo is transferred to the women's uterus. The basic steps in a IVF treatment cycle are ovulation enhancement (stimulating the development of more than one egg in a cycle), egg harvest, fertilization, embryo culture, and embryo transfer.
IVF is a reasonable choice of treatment for couples with various types of infertility. Initially it was only used when the woman had blocked, damaged or absent fallopian tubes (tubal factor infertility). IVF is now also used to circumvent infertility caused by endometriosis or by any one of a number of problems in the male. Many programs use IVF to treat couples that are infertile due to immunologic factors or other unexplained reasons. This procedure is practically safe from all complications and free from any dangers to mental health.
