For those men in the Millennial generation and Generation Z who would like to have children, Jason Nolan offers this warning: male infertility may impact you. Sooner than you might think. In part three, Jason talks about his bout with prolactinoma - a pituitary tumor that caused his body to produce estrogen instead of testosterone. Doctors believe the tumor came from longtime exposure to anti-fouling paint made with a substance that’s now banned worldwide - tributyltin oxide or TBT.
Before a second and painful treatment procedure using gamma knife radiation successfully removed the tumor, doctors found that it had rendered him infertile. More men may soon find themselves in similar straights as a study completed by the Hebrew University of Jerusalem in 2017 found that sperm counts among men in the West have more than halved in the past 40 years. The study also found that sperm counts among test subjects continued to drop by an average of 1.4 percent per year.

Interview with science writer Helen Scales, by Meera Senthilingham, Chemistry World’s Chemistry in its Element (podcast) about the work of marine biologist Stephen Blaber in 1970 when he discovered that female sea snails on the British Isles were developing male genitalia. The male genitalia were so large that they blocked the oviducts, preventing fertilization - otherwise known as imposex. In essence they were sterile. Eventually biologists determined TBTs caused the mutation. https://www.chemistryworld.com/podcas...
