Reproductive hormones
a. Estrogen
Estrogen is produced by the ovaries. There are many types of estrogen but the most important role in reproduction is estradiol. Estrogen is useful for the formation of the characteristics of sexual development in women is breast formation, hollow body, pubic hair, and others. Estrogen is also useful in menstrual cycles with endometrial thickness forming, maintaining the quality and quantity of cervical and vaginal fluids suitable for sperm penetration.
b. Progesterone
This hormone is produced by the corpus luteum. Progesterone maintains the endometrium thickness so it can receive zygot implantation. Progesterone levels be maintained for three months at the beginning of pregnancy until the placenta to form the hormone HCG.
c. Gonadotropin Releasing Hormone
GnRH is a hormone produced by the mus in the brain. GnRH stimulates the release of F Stimulating Hormone) in the pituitary. When estrogen levels high then estrogen will provide feedback to the hypothalamus that GnRH levels will be low, otherwise.
d. FSH (Follicle Stimulating Hormone) and LH (Luteinizing Hormone)
Both of these hormones called gonadotropoin hormone produced by the pituitary due to stimulation of GnRH. FSH causes the follicle maturation. The mature follicle will release the ovum. Later this follicle will become the corpus luteum and maintained for a certain time by LH.
Hormone production could decrease frequent with increasing age. These hormones are produced during the most productive women, ranging from the age of 14 years and began to decline when entering the age of 40 years, until the woman enters menopause.
