John Edmond Buster, M.D., (born July 18, 1941) working at the University of California at Los Angeles School of Medicine, directed the research team that performed history's first embryo transfer

 to another woman who gave birth to the infant 38 weeks later. The sperm used in the artificial insemination came from the husband of the woman who bore the baby.

This scientific breakthrough established standards and became an agent of change for women suffering from the afflictions of infertility and for women who did not want to pass on genetic disorders to their children. Donor embryo transfer has given women a mechanism to become pregnant and give birth to a child that will contain their husband’s genetic makeup. 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.

Prior to this, thousands of women who were infertile, had adoption as the only path to parenthood. This set the stage to allow open and candid discussion of embryo donation and transfer. This breakthrough has given way to the donation of human embryos as a common practice similar to other donations such as blood and major organ donations. At the time of this announcement the event was captured by major news carriers and fueled healthy debate and discussion on this practice which impacted the future of reproductive medicine by creating a platform for further advancements in woman's health.

Building upon Dr. Buster’s groundbreaking research and since the initial birth announcement in 1984, well over 170,000 live births resulting from donor embryo transfer have been and continue to be recorded by the Centers for Disease Control(CDC) in the United States to infertile women, who otherwise would not have had children by any other existing method.

Research

Dr. Buster’s forty years of research and clinical practice in reproductive medicine include numerous published studies in steroid physiology, pre-implantation embryology, pregnancy loss, and menopausal hormone replacement therapy.

One of Dr. Buster’s earliest research studies focused on steroid hormone radioimmunoassay (RIA). He reported an RIA for the androgen prohormone, dehydroepiandrosterone sulfate (DHEA-S), the direct measurement of which was shown to be possible in un-extracted serum. Refined versions of his methodology are used today in the diagnosis and management of androgen excess disorders in women (7).

Dr. Buster’s development of a simple nonchromatographic RIA to measure un-conjugated estriol in pregnancy serum led to more refined versions of this method that are used today in the early diagnosis of chromosomal abnormalities in mid-trimester pregnant women (8). He also described for the first time the simultaneous progression of multiple androgens, progestins, and estrogens concentrations in maternal blood throughout all three trimesters of pregnancy and into the onset of labor.

 at Los Angeles School of Medicine, Dr. Buster and his team developed a revolutionary technique based on in-vivo fertilization and uterine lavage – a method adapted from the commercialization of bovine embryo transfer in the cattle industry – as a means to transfer human blastocysts from fertile woman donors to ovulating or agonadal infertile recipient women (6) Specifically, the group developed a simple office procedure in which blastocyst

, which had been deliberately created from in vivo fertilization in the donor’s body using infertile recipient’s husband sperm, were transferred to produce pregnancy in an infertile recipient woman. In February 1984, the historical first live birth, followed 3 months later by a second live birth, resulted from these techniques and was reported by Dr. Buster and his team.

. The product – a trans-dermal patch – is designed to deliver chemically identical testosterone directly into the micro vascular circulation-much like an artificial endocrine organ. Dr. Buster was lead investigator in a major study that demonstrated the effectiveness of this patch to treat decreased sexual desire in oophorectomised, postmenopausal women (13). These patches are in use outside of the United States to treat hypoactive sexual desire in women who are deficient of androgens.

Most recently, Dr. Buster served as lead investigator in another major study demonstrating the effectiveness of an estradiol mist, which has pharmacology similar to those of a trans-dermal estrogen patches (14). Sold in the United States by TherRx Corporation under the name Evamist, the spray offers additional margins of safety and convenience over traditional oral and patch-administered estrogen's. Evamist won FDA approval in 2007. Dr. Buster's Phase III Study for Evamist was published in the Journal, Obstetrics & Gynecology, in June 2008.
