Although donor embryo transfer as practiced today has evolved from the original non-surgical method, it now accounts for approximately 5% of in vitro fertilization recorded births.
His center also pioneered various other techniques that increase the chances of successful in vitro fertilization, such as preimplantation genetic diagnosis.
Today, moreover, human beings have begun to penetrate into the interior of their own bodies, transplanting organs, intervening in their neurochemistry, practicing in vitro fertilization, and even manipulating their genes.
Wider interspecific hybrids can be made via in vitro fertilization or somatic hybridization, however the resulting cells are not able to develop into a full organism.
After egg retrieval for a cycle of in vitro fertilization, methylprednisolone may be prescribed to prevent the body from rejecting the embryos being transferred, up to the time of implantation.
To date, he has explored issues such as organ donation, genetic engineering, fertility treatment, in vitro fertilization, research funding, managed care, medical malpractice, medical tourism, drug research, and organ transplantation.
In vitro fertilization makes breeding cheetahs easier because researchers do not have to transport cheetahs from the wild to breed with the cheetahs in captive-breeding programs.
