Progesterone…The “Feel Good” Hormone
Many biological functions rely on hormones to occur. Hormones play a critical role in multiple aspects of fertility, and reproduction processes can be wholly impeded if just one hormone is not sufficiently available in the body. Progesterone, which is often referred to as the "feel-good" hormone because of its ability to calm GABA receptors is just one important reproductive hormone, but it plays an important role in multiple phases of reproduction. Take a closer look at progesterone and fertility according to western medicine, as well as how Traditional Chinese Medicine (TCM) offers even more insight.
The Role of Progesterone in Reproduction
Progesterone plays a vital role in the process of ovulation. During the first half of the cycle, the follicle-stimulating hormone (FSH) stimulates the ovary to produce an egg, and the estrogen hormone helps the lining of the uterus to thicken. During the second half of the cycle, progesterone is released from the ovary to prepare the uterus for a fertilized egg. It helps thicken the lining of the uterus, making it a more suitable environment for a fertilized egg to implant. If the levels of progesterone are too low, then it can lead to a condition called luteal phase defect (LPD). This is a condition where the lining of the uterus does not thicken enough for a fertilized egg to implant. As a result, the woman may have difficulty becoming pregnant.
Progesterone doesn't just get the uterus prepared for embryo implantation, it also supports an embryo once it is formed. One key way that the hormone does this is by regulating trophoblast cells and the migration of the embryo to the proper area. This is one reason why women who may have progesterone deficiencies may be more prone to miscarriage early in pregnancy.
Symptoms Associated with Progesterone Deficiency
Low progesterone levels can cause issues with fertility, but other symptoms may include:
Amenorrhea (no menstrual cycle) or menstrual irregularities
Hot flashes
Low sex drive
Mood changes
Headaches
Causes of Low Progesterone
Low progesterone levels can be caused by a variety of factors, including stress, underactive thyroid, and poor nutrition. Obesity can also be a factor as it can lead to a decrease in progesterone levels. Additionally, certain medications and medical conditions can also lead to low progesterone levels. In these cases, the underlying cause should be treated to restore the balance of hormones. If low progesterone levels are the cause of fertility problems, then there is an option to be prescribed supplemental progesterone in the form of pills, creams, or injections. This can help to increase the levels of progesterone in the body and reduce the risk of miscarriage. Additionally, other treatments may be recommended, such as lifestyle changes or dietary and exercise modifications, to help increase fertility.
A Look at Low Progesterone in Traditional Chinese Medicine
Short luteal phases, which can be due to low progesterone levels, are deemed as a Kidney Yang deficiency in TCM. This type of syndrome can be accompanied by a sore lower back and/or knees, feeling cold and having cold extremities, edema, forgetfulness, spiritual fatigue, and copious amounts of clear urine. Nourishing the blood and warming the kidney immediately after ovulation are thought to be highly important in encouraging fertility. Other factors like pathogenic interferences and poor circulation may also be considered when targeting issues with either menstruation or fertility. In TCM, both acupuncture and certain nutritional choices and herbal medicine are often recommended for short luteal phases.
