Carl Axel Gemzell

Carl Axel Gemzell (January 4, 1910 in Motala, Sweden – February 11, 2007 in Norrtälje, Sweden) was a Swedish physician and pioneer in reproductive endocrinology.

Life

Gemzell studied medicine at the Karolinska Institute and was registered as a physician in 1940.^[1] After training in surgery and obstetrics and gynecology he studied experimental endocrinology at the Wenner-Gren Institute and received his PhD in 1948. Subsequently, he worked at the Institute for Experimental Biology of the University of California, Berkeley before returning to Sweden. He became professor in Ob-Gyn at the Uppsala University Faculty of Medicine. After his mandatory retirement in Sweden in 1975, he moved to the USA where he continued to work at SUNY Downstate Medical Center, Brooklyn, New York, and later at the University of Puerto Rico in San Juan before he retired in Florida and, after the death of his wife, returned to Sweden.

Work

Gemzell developed methods to extract the human growth hormone and human gonadotropins from cadaver pituitary glands. In 1958 Gemzell was the first to show that extracted gonadotropins containing FSH could be used as fertility medication to stimulate ovulation in women with anovulatory infertility. Ovulation stimulation using FSH medication became the basis of modern infertility therapy such as IVF. First pregnancies were achieved in 1961 and Gemzell recognized early that multiple pregnancy and the ovarian hyperstimulation syndrome were major side effect of the therapy.^[2] Gemzell’s pituitary gonadotropin preparation was soon replaced by FSH extracts from urine of postmenopausal women by a method that was developed by Piero Donini and later marketed as Pergonal. Decades later pituitary extractions were proven to be unsafe as Creutzfeldt–Jakob disease could be transmitted.^[3]

In 1960 Gemzell and Leif Wide presented a pregnancy test based on in-vitro hemagglutination inhibition, a first step away from in-vivo pregnancy testing.^[4][5] This test initiates a series of improvements in pregnancy testing leading to the contemporary at-home testing.^[5]

Gemzell was a collector of modern paintings and drawings. A part of his collection was publicly exhibited at the Moderna Museet in Stockholm in 1996.

The Gemzell Prize is awarded annually to medical researchers by the University of Uppsala since 1977.
