The menstrual cycle is practically controlled by a system of hormones that is necessary for reproduction, and when the hormone reaches a heightened level, something called estradiol is made, then the stimulation of the ovaries by a luteinizing hormone.
Once that hormone begins developing, the ovaries make an egg that quickly becomes an ovum. The ovary then releases one egg or two during ovulation. The endometrium (the part that sheds its own cells for the menstruation) peaks after ovulation and changes the lining of the uterus to prepare for the hectic process of pregnancy and child labor.

Biodiversity is essential in medicine as most active chemicals used to make medicines are derived from plants or other organisms. Climate change today threatens species that are vital to medicine. An example would be coral reefs. Studies have been done on reefs that look at fighting cancers, HIV and other ailments. One of the richest zones of biodiversity is the tropics and this region is under threat from global warming and deforestation. It is important to preserve these species for use in future medicinal research. <span />
