What is Progesterone?
Progesterone is a steroid hormone that plays a crucial role in various physiological processes. Traditionally linked with female fertility and pregnancy, it is involved in the menstrual cycle and implantation and is essential for pregnancy maintenance [1]. Progesterone is also recognized as a key physiological component of not only the menstrual cycle and pregnancy but also as an essential steroidogenic precursor of other gonadal and non-gonadal hormones such as aldosterone, cortisol, estradiol, and testosterone [2].
Uses of Progesterone
Progesterone has a wide range of applications in human medicine. As discussed, It is used in maintaining pregnancy, preventing preterm labor, treating various gynecological pathologies, and lowering the adverse effects of menopause [3]. It is also used in the treatment of patients undergoing assisted reproductive technology procedures as a luteal phase support [4].
Progesterone is also used to prevent spontaneous preterm birth, hormone replacement therapy, and other gynecological conditions[5]. It has been proposed and extensively used in the treatment of different gynecological pathologies, as well as in assisted reproductive technologies and in pregnancy maintenance [1].
In addition to its role in reproduction, Progesterone regulates several biologically distinct processes in other tissues, particularly in the nervous system and the vessels[6].
What is Estrogen?
Estrogen is one of the most influential female sex hormones, essential for reproduction [7]. It is produced mainly in the ovaries and other places such as fat tissue, adrenal glands, liver, and breasts [8]. There are several different kinds of estrogen, each playing a significant role at various stages of a woman's life. The most active type of estrogen is estradiol, which is crucial during the years when a woman is menstruating [8].
Uses of Estrogen
Estrogen has a wide range of uses due to its diverse effects on the body. It is the central component in 6 of the 100 most prescribed medications in the United States today [9].
One of the primary uses of estrogen is in the treatment of menopausal symptoms such as hot flashes, night sweats, and vaginal dryness [10, 11]. It is also used to prevent osteoporosis, a condition in which the bones become thin and weak and break easily, in women who are experiencing or have experienced menopause [11].
Estrogen is also used to relieve symptoms of low estrogen in young women who do not produce enough estrogen naturally [11]. Some estrogen brands are also used to reduce symptoms of some types of breast and prostate cancer [11].
In addition to these uses, estrogen has been found to protect against obesity, insulin resistance, and cardiovascular disease [10, 9]. It also plays a vital role in managing the reproductive system, protecting bones, and helping skin heal from bruises and injuries [12].
