Gonadotropic cells are endocrine cells in the anterior pituitary that produce the gonadotropins, such as the follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
Urofollitropin
Urofollitropin is a purified form of follicle-stimulating hormone (FSH) that is manufactured by extraction from human urine and then purified to remove various proteins and other substances.
Androstenedione
Androstenedione may refer to:
* 4-Androstenedione (androst-4-ene-3,17-dione) – an endogenous weak androgen and estrogen and intermediate to/prohormone of testosterone
* 5-Androstenedione (androst-5-ene-3,17-dione) – a prohormone of testosterone and hence an androgenic-anabolic steroid
* 1-Androstenedione (5α-androst-1-ene-3,17-dione) – a prohormone of 1-testosterone (Δ1-DHT) and hence an androgenic-anabolic steroid
Ovulation
Ovulation is the release of egg from the ovaries.
Premature ovarian failure
Premature ovarian failure (POF), also known as premature ovarian insufficiency (POI), or primary ovarian insufficiency is the loss of function of the ovaries before age 40.
Menotropin
Menotropin (also called human menopausal gonadotropin or hMG) is a hormonally active medication for the treatment of fertility disturbances.
Uterine gland
Tube-like uterine glands, lined by ciliated columnar epithelium, are found in the functional layer of the uterine endometrium.
Activin and inhibin
Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects.
Lactation
Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young.
Syncytiotrophoblast
Syncytiotrophoblast (from the Greek 'syn'- "together"; 'cytio'- "of cells"; 'tropho'- "nutrition"; 'blast'- "bud") is the epithelial covering of the highly vascular embryonic placental villi, which invades the wall of the uterus to establish nutrient circulation between the embryo and the mother.
Arcuate nucleus
The arcuate nucleus (or infundibular nucleus) is an aggregation of neurons in the mediobasal hypothalamus, adjacent to the third ventricle and the median eminence.
Human placental lactogen
Human placental lactogen (hPL), also called human chorionic somatomammotropin (HCS), is a polypeptide placental hormone, the human form of placental lactogen (chorionic somatomammotropin).
Salpingitis isthmica nodosa
Salpingitis isthmica nodosa, also known as diverticulosis of the Fallopian tube, is nodular thickening of the narrow part of the uterine tube, due to inflammation.
Bifluranol
Bifluranol (INN, BAN) (brand name Prostarex) (former developmental code name BX-341) is an non-steroidal estrogen of the stilbestrol group related to diethylstilbestrol that is used as an antiandrogen in the United Kingdom in the treatment of prostate cancer.
Prolactin cell
Prolactin cell (also known as epsilon acidophil, lactotrope, lactotropic cell, lactotroph, mammatroph, mammotroph) is a cell in the anterior pituitary which produces prolactin in response to hormonal signals including dopamine which is inhibitory and thyrotropin-releasing hormone which is stimulatory.
Estrogen insensitivity syndrome
Estrogen insensitivity syndrome (EIS), or estrogen resistance, is a form of congenital estrogen deficiency caused by a defective estrogen receptor (ER), specifically ERα.
Delayed puberty
Puberty is described as delayed puberty with exceptions when an organism has passed the usual age of onset of puberty with no physical or hormonal signs that it is beginning.
Relaxin family peptide hormones
Relaxin family peptide hormones in humans are represented by 7 members: three relaxin-like (RLN) and four insulin-like (INSL) peptides.

The ERRs are orphan nuclear receptors, meaning the identity of their endogenous ligand has yet to be unambiguously determined.
Magnocellular neurosecretory cell
Magnocellular neurosecretory cells are large neuroendocrine cells within the supraoptic nucleus and paraventricular nucleus of the hypothalamus.
Theca interna
Theca interna cells express receptors for luteinizing hormone (LH) to produce androstenedione, which via a few steps, gives the granulosa the precursor for estrogen manufacturing.
Premature thelarche
Premature thelarche is a rare medical condition that is characterized by isolated breast development (thelarche being the onset of breast development) at a very early age with no other signs of sexual maturation.
