Clomiphene citrate, more commonly known by its brand names Clomid and Serophene, is a medication prescribed to women to stimulate ovulation in order to treat infertility. It stimulates ovulation in women who do not ovulate or ovulate irregularly. This drug was created by Dr. Frank Palopoli in 1956 while he worked for Merrell Company. It first successfully induced ovulation in women in 1961 and was approved by the Federal and Drug Administration (FDA) in 1967. This medication can be used to help women conceive naturally, to time ovulation for intrauterine insemination, or to stimulate the maturation of eggs to be extracted and used in procedures such as in vitro fertilization (IVF), gamete intrafallopian transfer (GIFT), and zygote intrafallopian transfer (ZIFT).

Howard Wilber Jones Jr. and his wife, Georgeanna Seegar Jones, developed a method of in vitro fertilization and helped create the first baby in the US using that method. Though the first in vitro baby was born in England in 1978, Jones and his wife's contribution allowed for the birth of Elizabeth Carr on 28 December 1981. Jones, a gynecologist and an obstetrician, researched human reproduction for most of his life.

Intracytoplasmic Sperm Injection (ICSI) is an assisted reproductive technique (ART) initially developed by Dr. Gianpiero D. Palermo in 1993 to treat male infertility. It is most commonly used in conjunction with in vitro fertilization (IVF) or a less commonly used technique called zygote intrafallopian transfer (ZIFT). In natural fertilization, the sperm must penetrate the surface of the female egg, or oocyte. When the male has a fertility problem such as low sperm count, malformed sperm shape, or sperm immobility, there is a significant decrease in the chance a healthy sperm will penetrate the outer surface of the oocyte. Other fertility problems ICSI can be used to overcome include the sperm having trouble attaching to the egg or the male having a blockage in his reproductive tract preventing normal ejaculation. In this procedure, the physician first obtains the sperm and oocytes from the male and female and then manually injects the sperm through a needle into the oocyte to fertilize it in an injection plate. The physician then places the fertilized egg into the female s uterus for implantation, following IVF procedures.

Zhang Lizhu is a Chinese gynecologist and researcher. For most of her career, she worked in the Peking Medical College Third Hospital, renamed in 2000, Peking University Third Hospital. There, she led a team of researchers and physicians in the study of human in vitro fertilization (IVF) and embryo transfer (ET) technology. Zhang and her colleagues contributed to the birth of the first test-tube baby in Mainland China in 1988.

Johns Hopkins Medical Center, located in Baltimore, Maryland, opened in 1889; its associated medical school opened four years later. Today the hospital, a leading research center, contains many departments, including a fertility center that is renowned for taking on difficult cases that have been rejected by other fertility clinics. The fertility center was founded by physician Georgeanna Seegar Jones in 1939 as the Division of Reproductive Endocrinology in the gynecology department. The division expanded once formal training in reproductive endocrinology began in 1973. With the growth of this department came new developments; by 1984 the center was offering a variety of assisted reproductive technologies (ART) for individuals unable to conceive a child naturally. Johns Hopkins gynecology department is ranked second out of 4,800 hospitals by the U.S. News & World Report's annual ranking for America's best hospitals in 2009-2010.

Intrauterine insemination (IUI), also known as artificial insemination, is one of the earliest and simplest assisted reproductive technologies (ART). With this technique, sperm from either a partner or donor (such as from a sperm bank) is inserted with a syringe into the woman's vagina during ovulation to increase the probability that fertilization will occur and lead to pregnancy. This procedure is most effective for couples with male fertility problems, such as impotence, though it is also used to treat idiopathic (of unknown cause) infertility, vaginismus (wherein the female involuntarily constricts her vagina), and hostile female cervical mucus that rejects the male's sperm. In the 1940s and 1950s cryopreservation facilitated the preservation of sperm through freezing methods for later use, such as in IUI.

On 10 March 1988, China's first baby conceived through human in vitro fertilization (IVF) and embryo transfer (ET), commonly referred to as a test-tube baby, was born at the Peking Hospital (PUTH) in Beijing. This birth was reported in numerous media reports as a huge step forward in China's long march to keep pace with global advances in science and technology. Led by gynecologist Zhang Lizhu, the PUTH research team had devoted more than four years to the human IVF-ET project. The team had to start by learning the basics of human egg morphology and embryology in order to design an IVF-ET strategy that was suited to the reproductive pathology affecting China's infertile population.

The Center for Reproductive Health was a fertility clinic run by a partnership of world-renowned fertility specialists from 1986 to 1995. The Center operated at three clinic locations under affiliation with the University of California Irvine 's Medical Center (UCIMC). The Center's renowned specialists and medical success stories attracted clients worldwide until evidence of highly unethical practices conducted by doctors there resulted in over one hundred lawsuits against the University. At issue was the doctors' misappropriation and unauthorized use of eggs and embryos. The three partners of the Center were indicted for mail fraud, for billing insurance companies for work not performed, and for violating California State legislation requiring consent to use eggs and embryos and outlawing egg and embryo theft. The three partners indicted for the unethical practices at the Center were Sergio Stone, a uterine surgery and hormonal treatment specialist, José Balmaceda, a Rockefeller Foundation fellowship award winner in reproductive endocrinology, and Ricardo Asch, director of the clinics and inventor of the gamete intrafallopian transfer (GIFT) assisted reproduction technique.

Georgeanna Seegar Jones was a reproductive endocrinologist who created one of America' s most successful infertility clinics in West Virginia and eventually, along with her husband Howard W. Jones MD, performed the first in vitro fertilization in America, leading to the birth of Elizabeth Jordan Carr. Jones was born in Baltimore, Maryland, on 6 July 1912. Her father, Dr. John King Beck Emory Seegar, was a practicing physician at the time working in the field of obstetrics. Early in her childhood Jones had a broken bone that eventually became infected and caused a great deal of pain, inspiring her to go into the field of medicine.

Zygote intrafallopian transfer (ZIFT) is an assisted reproductive technology (ART) first used in 1986 to help those who are infertile conceive a child. ZIFT is a hybrid technique derived from a combination of in vitro fertilization (IVF) and gamete intrafallopian transfer (GIFT) procedures. Despite a relatively high success rate close to that of IVF, it is not as common as its parent procedures due to its costs and more invasive techniques. Some patients prefer ZIFT, however, considering it more natural because the fertilized oocyte, the zygote, is placed in the woman's body for implantation much sooner than with IVF.
