Quality minimal. All living things reproduce. This is something that sets the living apart from non-living. Even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. This chapter describes the different parts of the female reproductive system: the organs involved in the process of reproduction, hormones that regulate a woman's body, the menstrual cycle, ovulation and pregnancy, the female's role in genetic division, birth control, sexually transmitted diseases and other diseases and disorders.

Human semen, too, triggers changes in the uterus, and might have wider effects on women, aimed at just one goal. The effects are most striking in fruit flies: seminal fluid can make the females eat more, lay more eggs and be less receptive to other males. Now a team led by Tracey Chapman at the University of East Anglia in Norwich, UK, has found that male fruit flies selectively alter the chemical make-up of their seminal fluid.

Semen has controlling power over female genes and behaviour

Im still a virgin, me and my boyfriend do NOT mind if i fall pregnant. I was just wondering if when a wet penis goes up me untill it hits the hymen, can I still get pregnant? If his penis has been in your vagina, you are not a virgin And sperm can get through the hymen, just like menstrual blood can come through the other direction. Best of luck.
