A luteoma is a tumor that occurs in the ovaries during pregnancy. It is associated with an increase of sex hormones, primarily progesterone and testosterone. [1] [2] The size of the tumor can range from 1 to 25 cm in diameter, but is usually 6 to 10 cm in diameter [3] and can grow throughout the duration of the pregnancy. [4]
Estrogen, progesterone, and human chorionic gonadotropin (hCG) levels throughout pregnancy. Estrogen, progesterone, and 17α-hydroxyprogesterone (17α-OHP) levels during pregnancy in women. [ 1 ] The dashed vertical lines separate the trimesters .
Physiological (i.e., non-pathological) causes that can increase prolactin levels include: ovulation, pregnancy, breastfeeding, chest wall injury, stress, stress-associated REM sleep, and exercise. [ 20 ] [ 4 ] [ 21 ] During pregnancy, prolactin increases can range up to 600 ng/mL, depending on estrogen and progesterone concentrations.
The levels of hCG in the body increase rapidly in the first few weeks of pregnancy, doubling every 48–72 hours. [7] The highest level of hCG is reached in week 10 or week 11, later the levels of hCG can be used to estimate the age of the fetus and monitor the progress of the pregnancy. [6]
Signs of hyperestrogenism may include heightened levels of one or more of the estrogen sex hormones (usually estradiol and/or estrone), lowered levels of follicle-stimulating hormone and/or luteinizing hormone (due to suppression of the hypothalamic–pituitary–gonadal axis by estrogen), and lowered levels of androgens such as testosterone (generally only relevant to males). [1]
In anembryonic pregnancy, levels of the pregnancy hormone human chorionic gonadotropin (hCG) typically rise for a time, which can cause positive pregnancy test results and pregnancy symptoms such as tender breasts. [2] [7] Because of the presence of hCG, an ultrasound is typically necessary to diagnose an anembryonic pregnancy. [3]
Treatment with progesterone in the third trimester of pregnancy has been shown to be associated with the development of ICP, and levels of metabolites of progesterone, particularly sulfated progesterone, [12] are higher in patients with ICP than unaffected women, suggesting that progesterone may have a bigger role than estrogen in ICP. [13]
Endometrial hyperplasia is a condition of excessive proliferation of the cells of the endometrium, or inner lining of the uterus.. Most cases of endometrial hyperplasia result from high levels of estrogens, combined with insufficient levels of the progesterone-like hormones which ordinarily counteract estrogen's proliferative effects on this tissue.
