A progesterone blood test is done to find out how much of the progesterone hormone is in a sample of blood. This female hormone is produced each time a mature egg is released from an ovary after a process referred to as ovulation. This hormone really helps to prepare the endometrium (uterine lining) to take the egg if sperm fertilizes it. If the egg goes without being fertilized, menstrual bleeding occurs and progesterone levels drop. Once the body?s hormonal balance has been restored by BHRT, the debilitating effects of aging are alleviated. You will be glad to know that BHRT is an anti aging solution available in Tampa.
