First manufactured in 1988 by Serono laboratories, recombinant gonadotropins are synthetic hormones that can stimulate egg production in women for use in fertility treatments. Recombinant gonadotropins are artificially created using recombinant DNA technology, a technology that joins together DNA from different organisms. In vertebrates, naturally-occurring gonadotropins regulate the growth and function of the gonads, known as testes in males and ovaries in females. Medical professionals can derive female gonadotropins from the urine of pregnant and post-menopausal women, often using it to facilitate in vitro fertilization, or IVF. With the rapid development of assisted reproductive technologies like IVF, demand for human-derived gonadotropins rose to a global yearly demand of 120 million liters of urine by the beginning of the twenty-first century, which resulted in a demand that could not be met by traditional technologies at that time. Therefore, researchers created recombinant gonadotropins to establish a safer and more consistent method of human gonadotropin collection that met the high demand for its use in fertility treatments.

Alan Osborne Trounson is a scientist from Australia who studies embryology and stem cells. His research has improved the success rates of in vitro fertilization, or IVF. IVF is a medical procedure in which scientists fertilize an egg cell with sperm outside of the body, often in a laboratory petri dish, then transfer the fertilized egg to a woman’s uterus to start pregnancy. Trounson also researched embryonic stem cells, or stem cells collected from embryos, and their potential for treating injuries and diseases. Additionally, Trounson led the Californian Institute for Regenerative Medicine, or CIRM, one of the largest agencies to fund stem cell research in California, from 2007 to 2014. Over the course of his career, Trounson developed several techniques that improved the effectiveness of IVF, including fertility treatments and cryopreservation, and supported stem cell research as a scientist and administrator.
