In vitro fertilisation In vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm outside the body, in vitro (in glass). The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilise them in a liquid in a laboratory.

In Situ, Ex Situ Conservation In situ and ex situ conservation focuses on the maintenance of species diversity within or away from their natural habitats, respectively.n vitro conservation involves the maintenance of ex-plants in a sterile, pathogen-free environment, and it is widely used for vegetatively propagated and recalcitrant-seeded species. This method offers an alternative to field gene banks.

In vitro fertilisation IVF techniques are also employed in gestational surrogacy, in which case the fertilised egg is implanted into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. In some situations, donated eggs or sperms may be used.n gamete intrafallopian transfer, eggs are removed from the woman and placed in one of the fallopian tubes, along with the man's sperm. This allows fertilisation to take place inside the woman's body. Therefore, this variation is actually an in vivo fertilisation, not an in vitro fertilisation.

Infertility and In Vitro Fertilization Once an embryo or embryos form, they are then placed in the uterus. IVF is a complex and expensive procedure; only about 5% of couples with infertility seek it out. However, since its introduction in the U.S. in 1981, IVF and other similar techniques have resulted in more than 200,000 babies.

Types of Insemination Types of Assisted Reproduction Technologies (ART) The most familiar ART procedures are intrauterine insemination (IUI) - known as artificial insemination - and in vitro fertilization (IVF). However, there are in fact several types of artificial insemination, each of which tries to help a woman conceive (without sexual intercourse) by placing sperm directly into a woman's reproductive tract.

Blastocyst The use of blastocysts in in-vitro fertilization involves culturing a fertilized egg for five days before implanting it into the uterus. It can be a more viable method of fertility treatment than traditional IVF. The inner cell mass of blastocysts is also a source of embryonic stem cells.
