In Vitro Fertilization,is a helpful reproductive technology in which one or more eggs are fertilized outside a females body. This system has been used widely in animal embryological research for decades, but only since 1978 has it been successfully used to human reproduction. The human reproduction process requires stimulation of the growth of multiple eggs by a daily injection of hormone medications. It is also possible to conduct IVF with none of the hormone medications; one egg would mature and be recovered. The eggs are obtained by one of two methods: sonographic egg recovery, the more common one of the two, that uses ultrasound guidance to obtain the eggs, oocytes, or laparoscopic egg recovery, in which retrieval is done through a small incision in the abdomen.

After the eggs have been retrieved, they are put in something called fluid medium, once the semen has been washed and produced it is put together with the eggs for approximately 18 hours.

Then the eggs are taken out, routed into a special growth medium, and then inspected about 40 hours later. If the eggs have been fertilized and developed normally, ...
... the embryos are transferred to the woman or a surrogants uterus.

Usually, many embryos are transferred to enlarge the possibility of pregnancy. If more than four eggs form into embryos, the donor can have the option of cryopreserving the remaining embryos for thawing and replacement in a following IVF cycle. (Cryopreservation is used to decrease the risk of many gestations [twins, triplets, etc.] if more than four embryos are replaced.) After the egg transfer, progesterone injections may be given daily to the recipient. The possibility of viable pregnancy is about 20 percent with one IVF process.

Similar techniques are also obtainable. In gamete intrafallopian transfer, is similar to doing IVF, but the harvested eggs and sperm are placed straight into the fallopian tubes, with fertilization happen in the womans body. In zygote intrafallopian transfer, the procedure is like to gamete intrafallopian transfer, but the beginning-stage embryos (zygotes) are positioned directly in the fallopian tubes. With super ovulation uterine capacitation enhancement (SOURCE), the woman can get daily hormone medications to stimulate the growing of multiple eggs. Once the eggs have reached the right step, intrauterine inseminations are done by using the partners specifically treated sperm. In some places the donor oocyte programs are available; the donated eggs are used by women unable to use their own eggs to get pregnant. The assisted reproductive technology is used to retrieve eggs from donors and mend embryos in the recipient.
