Publisher Summary Successful in vitro fertilization (IVF) may be approached by either of two methods that differ substantially in concept. One method of obtaining normal oocytes for IVF is to rely on the precise determination of periovular changes to predict the exact time of ovulation in the natural or spontaneous ovulatory cycle.

Abstract Most young couples trying for a baby will eventually conceive within 18 months and only one in seven couples in the UK remain subfertile after this period. In 80% of these subfertile women one or more causative factors are attributable; and some may be associated with significant co-morbidities.

In vitro fertilization (IVF) is a technical process in which retrieved oocytes are fertilized outside the body. The developing embryos grow in a laboratory environment and are subsequently transferred into the woman's uterus. The IVF technique was first introduced as a treatment for infertility in 1978 and success rates have steadily increased in the ...

Fertilization abnormalities in human in-vitro fertilization
Human Reproduction, 1992Fertilization abnormalities (premature chromosome condensation of spermatozoa (PCC), triploidy, haploidy) were analysed in order to determine their origin. PCC occurs in 9% of unfertilized oocytes and seems to be the consequence of a failure of oocyte activation, leading to the continuing presence of cytoplasmic chromosome-condensing factors, causing ...

Two sperm cells of a pollen grain or pollen tube are involved in fertilization in angiosperms; one sperm fuses with the egg and the other one with the central cell. These processes, well known as double fertilization, result in the formation of an embryo and an endosperm tissue.

International Anesthesiology Clinics, 2003In vitro fertilization (IVF) is a broad term used to describe the process of obtaining an egg and uniting it with sperm in a laboratory setting, and subsequently placing the fertilized egg into the uterus in hopes of achieving a live birth. In terms of anesthesiology, IVF primarily means oocyte retrieval.

Mycoplasmas and in vitro fertilization
Fertility and Sterility, 1987Semen samples taken from 135 patients attending an in vitro fertilization clinic were shown to be colonized, 53 with Ureaplasma urealyticum (39%) and 16 with Mycoplasma hominis (12%). An unidentified mycoplasma species was isolated from the sperm of two patients. M.
