The Charleston Daily Mail, Nov. 3, 1933: “Sex Change Possible, Physician Maintains”

OKLAHOMA CITY, Nov. 3 (UP). — A man may “turn into a woman,” just as a California girl has assumed some of the physical characteristics of a man. Dr. Herbert M. Evans, professor of anatomy at University of California, said today.

“Our experiments with chickens show conclusively that hens have stopped laying eggs, grown combs and virtually become roosters,” said Dr. Evans, here for a clime meeting.

“It is possible that the woman might be turning into a man. ”Of course the change could not be complete in the human being except in the secondary sexual characteristics such as to contours of the, body, growth of coarse hair, change of voice and the like.

‘It also would be possible for a man to turn into a woman.”

Dr. Evans explained, however, that the fundamental characteristics of man or woman could not be sufficiently changed to cause any difference, without removal or addition of certain glands.

The specialist, noted since his work 13 years ago when he separated the sex and grow the hormones of the pituitary gland after long research, explained the present day need for more research in the branch of medicine dealing with glands of internal secretion.

“Medicine has practically reached the position where it has control of all infectious diseases, but only a start has been made in the field dealing with internal secretion glands,” he said.

From Wikipedia:

Herbert McLean Evans (September 23, 1882–March 6, 1971) was a U.S. anatomist and embryologist.

He was born in Modesto, California. In 1908, he obtained his medical degree from Johns Hopkins University, eventually becoming its associate professor of anatomy. Evans moved back to California in 1915 and was made professor of anatomy at the University of California, in Berkeley, California, and held that position until his death.

His medical research at Berkeley addressed problems relating to human nutrition, endocrinology, embryology, and histology. In 1918, his research into the number of human chromosomes led him to believe the number to be 48, when most people assumed the number to be much higher. It was only later discovered that the correct figure was 46. Evans had much greater success however with hormones extracted from the anterior lobe of the pituitary gland. He isolated Human Growth Hormone, which was essential for human growth and development. In 1922 along with Katharine Scott Bishop, during feeding experiments on rats, he co-discovered Vitamin E which is needed for human reproduction. Evans became director of the Institute of Experimental Biology at Berkeley, in 1931. He continued his research on vitamine E and was finally able to isolate the pure compound from wheat germs in 1937. He also determined the formula C29H50O2. He was also instrumental in developing reproductive systems research with Miriam Sipson and C.H. Li, by studying the oestrus cycle of rats. Evans is also credited with developing Evans blue, a method which determines blood volume in humans and animals.

He died in Berkeley, California, aged 88.
