If you’re currently using fertility medications, here’s some reassuring news: a recent study from the European Society of Human Reproduction and Embryology found “little evidence” that fertility hormones significantly elevate the long-term risk of developing breast or gynecological cancers.
The research tracked 12,193 women who underwent infertility treatments between 1965 and 1988 in the United States, with follow-ups extending until 2010. Out of these, 9,892 women were monitored for their cancer outcomes. According to Dr. Alex Johnson from the University of Illinois at Chicago, who presented the findings, “While there’s biological reasoning to suspect a link, studies on fertility drugs in relation to breast and gynecological cancers show mixed results. Some indicate increased risks, others suggest a decrease, and many show no significant relationships at all.”
Johnson notes that most previous studies were limited in scope, often having small sample sizes and brief follow-up periods, which made it difficult to account for other cancer risk factors, such as conditions like endometriosis or anovulation that may influence cancer risk independently.
Fertility medications, particularly clomiphene and hormones derived from human sources like human menopausal gonadotropins (hMG) and follicle-stimulating hormone (FSH), work by boosting female hormones such as estradiol and progesterone—known contributors to certain cancers. However, since clomiphene was the predominant fertility drug used before hMG and FSH became popular in the 1980s, it’s likely that the elevated risk seen in women who had never been pregnant relates more to their infertility issues than to the medications themselves.
Among the 9,892 participants tracked for 30 years, there were 749 cases of breast cancer, 119 cases of uterine cancer, and 85 cases of ovarian cancer identified.
