Back in 1969, Dr. David Reuben published a little book titled Everything You Always Wanted to Know About Sex (But Were Afraid to Ask). People couldn’t wait to read it because frankly they were afraid to ask. Prof. Harper, professor of Reproductive Science at University College London and a longtime fertility researcher, has written a 2021 version that includes everything a body could possibly want to know about sex and reproduction. Loaded with research and study results, it’s not easy reading, but here are the facts about menstruation, fertility, the sexual body parts, how to have good sex, contraceptives, sexually transmitted diseases, how a baby gets made, egg freezing, in vitro fertilization, menopause, and the future of reproductive science--artificial wombs that could be implanted in men! Eggs and sperm manufactured to order from stem cells! Harper is very frank. If you want to get pregnant the natural way, you should do it before age 35. Many of the treatments offered to increase fertility are a waste of money. Everything goes better with a healthy diet and exercise. This is a good book to keep on the shelf so that when you have a question, you can look it up
