Document Summary
Sex and gender a romance (by emily martin): Changes in the existing dominant scientific paradigm aren"t certain. Her goal is to shine a bright light on the gender stereotypes hidden within the scientific language of biology. Ovarian fallacies containing ova are present at birth. 400 germ cells mature in a female"s lifetime. Of the 7 million oogonia, or egg germ cells, in the female embryo, most degenerate in the ovary. Degeneration goes on throughout a woman"s life. 2 trillion sperm are made in the lifetime of a man. Eggs can be seen with the naked eye. Sperm/eggs stick together via adhesive molecules on the surface. Ruth hershberger argues that the female reproductive system is more independent than a man"s (1948 book) The zona, the inner vestment of the egg, formed an impenetrable barrier prior to hopkins research. Molecules on the sperm are proteins, and have packets called ligands . Egg coat has more functions than sperm receptors.
