Health News Overview:. In vitro fertilization IVF is the joining of a woman's egg and a man's sperm in a laboratory dish. In vitro means outside the body. Fertilization means the sperm has attached to and entered the egg. Normally, an egg and sperm are fertilized inside a woman's body. If the fertilized egg attaches to the lining of the womb and continues to grow, a baby is born about 9 months later.
In vitro fertilization is usually called as IVF. Generally, it is the method of fertilizing an egg with sperm in the laboratory dish. Once in vitro fertilization is successful then it is combined with a method called as embryo transfer. This procedure is used in order to set the embryo in your uterus. In vitro fertilization and embryo transfer basically consist of five steps.
Progress in the field of assisted reproduction, and particularly micromanipulation, now heralds a new era in the management of severe male factor infertility, not amenable to medical or surgical correction. By overcoming natural barriers to conception, in vitro fertilization and embryo transfer IVF-ET , subzonal sperm insemination, partial zona dissection, and intracytoplasmatic injection of sperm ICSI now offer couples considered irreversibly infertile, the option of parenting a genetically related child. However, unlike IVF, which necessitates an optimal sperm number and function to successfully complete the sequence of events leading to fertilization, micromanipulation techniques, such as ICSI, involving the direct injection of a spermatozoon into the oocyte, obviate all these requirements and may be used to alleviate severe male factor infertility due to the lack of sperm in the ejaculate due to severely impaired spermatogenesis non-obstructive azoospermia or non-reconstructable reproductive tract obstruction obstructive azoospermia.
In vitro fertilization, popularly referred to as IVF, has captured the attention of the public since its sensational introduction in Today assisted reproductive technology is available throughout most of the civilized world, and the practice is largely different from that used during the early days. Refinements in laboratory technology and clinical practice have allowed IVF to evolve into a medical procedure that is efficient, safe, readily accessible, and relatively affordable.
