Prolactin (PRL, synonyms: prolactin; lactotropic hormone (LTH); lactotropin) is a hormone from the anterior pituitary (pituitary gland) that acts on the mammary gland and controls milk production in women after pregnancy. Prolactin itself is inhibited by Prolactin Inhibiting Factor (PIF), which is produced in the hypothalamus. This is identical to dopamine. Prolactin shows fluctuations during … Prolactin (PRL)
Sex hormone-binding globulin (SHBG) is a transport and storage protein of sex hormones. This is primarily testosterone, the male sex hormone. Furthermore, it also binds all 17-β-hydroxylating steroids (e.g. estrogens). SHBG is synthesized in the liver. It increases with age, during pregnancy, and after menopause. The process Material needed Blood serum Preparation of the patient … Sex Hormone-Binding Globulin (SHBG)
The TRH test is used to detect thyroid hormone resistance or other thyroid disorders that could not be reliably detected by standard tests. TRH (thyroid-releasing hormone; produced in the hypothalamus) stimulates the pituitary gland to release TSH (thyroid-stimulating hormone) and prolactin (breast growth and milk secretion are promoted by prolactin). Indications Evidence of thyroid hormone … TRH Test
TSH (thyroid stimulating hormone) level refers to the concentration of the hormone that regulates thyroid hormones (T3, T4). TSH also has a stimulating effect on the growth, iodine uptake and thyroid hormone production of the thyroid gland. TSH production is primarily regulated by the pituitary gland and the hypothalamus. Thyrotropin-releasing hormone (TRH) stimulates the anterior … TSH (Hormone)
The fT3 value refers to the concentration of free triiodothyronine.The two thyroid hormones, T3 (triiodothyronine; triiodothyronine) and T4 (thyroxine), are present in protein-bound form and become biologically active when needed by conversion to the free form. In the laboratory, this free form is measured. T3 has a fivefold stronger effect than T4 and 80% of … FT3 (Triiodothyronine)
The fT4 value refers to the concentration of free thyroxine. The two thyroid hormones, T3 (triiodothyronine) and T4 (thyroxine), are present in protein-bound form and become biologically active when needed by conversion to the free form. In the laboratory, this free form is measured. T3 has a fivefold stronger effect than T4 and 80% of … FT4 (Thyroxine)
Luteinizing hormone (LH or also called lutropin) is a hormone from the pituitary gland (hypophysis) that, with the cooperation of follicle-stimulating hormone (FSH), controls follicle maturation (egg maturation) and ovulation (ovulation) in women. It is also involved in estrogen and progesterone synthesis. In men, LH (interstitial cell stimulating hormone = ICSH) controls the production of … Luteinizing Hormone (LH)
The estrogen test (estrogen test; estrogen-progestin test) is performed, if necessary, following a negative progestin test in amenorrhea (absence of regular bleeding). Estrogens are female sex hormones. They are mainly produced in the ovaries (Graafian follicle, corpus luteum), but also to a lesser extent in the adrenal cortex. The estrogen concentration changes in the course … Estrogen Test
Progesterone is a hormone from the group of progestins. It is produced in the ovaries in the corpus luteum (in the corpus luteum) and increases during the luteal phase (corpus luteum phase) – on the 5th-8th day after ovulation (ovulation) is the maximum serum level – and during pregnancy. Progesterone is responsible for nidation (implantation … Progesterone: Effects
17-Beta-estradiol (estradiol, estradiol, E2) is a form of the female sex hormone.It is produced primarily in the ovaries (Graafian follicle, corpus luteum) in women and in the placenta in pregnant women. The concentration of estradiol changes during the female menstrual cycle.In men, production takes place in the testes and adrenal cortex.Estradiol is the most potent … 17-Beta Estradiol
Chromosome analysis is the oldest genetic examination method. As part of this procedure, a karyogram (ordered representation of all chromosomes in a cell) is made. This allows changes in the number as well as in the structure of the chromosomes to be detected (numerical/structural chromosomal aberrations). Humans have 46 chromosomes. The chromosome pairs 1-22 are … Chromosome Analysis
The clomiphene test is a functional test of the hypothalamus (section of the diencephalon). Clomiphene (3-methoxy-17-epiestriol) is an ovulation trigger from the group of antiestrogens. The term ovulation trigger refers to drugs that can trigger ovulation (ovulation) by stimulating endogenous (the body’s own) hormones. Clomiphene acts via feedback inhibition of estrogens. Thus, the central antiestrogenic … Clomifentest
