To help you navigate the clinical, biological, and metabolic explanations throughout the HimZen articles, we have compiled a glossary defining the essential terms of women's health and hormonal wellness.
Allopregnanolone (ALLO)
A neurosteroid metabolite of progesterone that crosses the blood-brain barrier and binds to GABA-A receptors in the brain, acting as a natural, calming agent to reduce anxiety and support sleep.
Anovulation
A menstrual cycle phase or condition where the ovaries fail to release an egg (ovulation) during a monthly cycle, preventing the formation of the corpus luteum and resulting in low progesterone.
Antral Follicles
Small, fluid-filled sacs in the ovaries containing immature eggs. The accumulation of these follicles (sometimes called a "string of pearls") on an ultrasound is a diagnostic marker of PCOS.
Corpus Luteum
A temporary endocrine gland formed in the ovary from the ruptured follicle after ovulation, responsible for synthesizing and secreting high levels of progesterone during the luteal phase.
Diindolylmethane (DIM)
A natural compound formed in the stomach when digesting cruciferous vegetables (like broccoli or Brussels sprouts), known to support the liver's healthy pathway of estrogen clearance.
Estradiol (E2)
The primary, most active and potent form of estrogen circulating in the body during a woman's reproductive years, responsible for tissue building, cardiovascular flexibility, and insulin sensitivity.
Estrogen Dominance
A relative hormonal state where estrogen levels are abnormally high in proportion to progesterone, often caused by poor ovulation, chronic stress (progesterone steal), or compromised liver clearance.
Follicle-Stimulating Hormone (FSH)
A gonadotropin hormone released by the pituitary gland that signals the ovaries to recruit and mature follicles at the start of the menstrual cycle.
Gonadotropin-Releasing Hormone (GnRH)
A hormone secreted by the hypothalamus in precise pulses that signals the pituitary gland to release FSH and LH.
HPG Axis (Hypothalamic-Pituitary-Gonadal Axis)
The three-way feedback communication highway between the brain stem and the ovaries that regulates the menstrual cycle, ovulation, and reproductive hormone synthesis.
Hirsutism
The abnormal growth of coarse, dark hair in male-pattern distributions (such as the face, chest, or back) in women, driven by elevated levels of free androgens (testosterone).
Luteinizing Hormone (LH)
A gonadotropin hormone released by the pituitary gland. A sharp, high pulse of LH (the LH surge) triggers the dominant follicle to rupture and release the egg (ovulation).
Myo-Inositol
A naturally occurring isomer of inositol that acts as an essential intracellular second messenger, carrying signals from insulin and FSH receptors directly to the inside of the cell.
Osteoblasts
Specialized bone cells responsible for synthesizing bone matrix and building new bone density, stimulated by mechanical loading and calcium availability.
Osteoclasts
Specialized bone cells responsible for breaking down bone tissue (bone resorption) to release minerals into the blood, inhibited by active estrogen signaling.
Pregnenolone
The master precursor steroid hormone synthesized from cholesterol, from which all other steroid hormones (progesterone, cortisol, DHEA, estrogen, testosterone) are manufactured.
Progesterone
The primary hormone secreted by the corpus luteum during the luteal phase of the cycle, responsible for calming the nervous system, supporting thyroid hormone conversion, and balancing the effects of estrogen.
Sex Hormone-Binding Globulin (SHBG)
A carrier glycoprotein produced by the liver that binds tightly to active sex hormones (testosterone, estrogen), regulating the amount of free, unbound hormone active in the bloodstream.
Theca Cells
Specialized endocrine cells in the ovaries that synthesize androgens (male hormones) in response to stimulation by Luteinizing Hormone (LH) and insulin.
Xenohormones
Foreign, synthetic chemical compounds (such as plasticizers or pesticides) that possess estrogenic activity, binding to and disrupting natural hormone receptor pathways.
