What is freemartinism and how it is caused?
Freemartinism is when a heifer has male sex characteristics but has underdeveloped female sex organs. It is caused by sharing a placenta with a twin bull calf. The male sex ho…rmones that is emitted by the male fetus as he develops in the womb inhibits the female's sex hormones, and consequently prohibits her from developing normal female reproductive organs. She retains the testosterone and develops bull-like characteristics after birth and as she gets older. Freemartins are sterile, so they're better off being raised for the freezer. (MORE)
