Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.

Hormonal markers of progression of maturation differ between sexes as well. Tracking of AMH and inhibin B levels can be useful in males, as well as gonadotropin and androgen levels earlier on in puberty. Females also have stable AMH levels, with gonadotropin levels being useful markers longer from between 8 and 4 times as long compared to as in ...
Human chorionic gonadotropin (hCG), progesterone, 17β-estradiol, endorphins and gonadotropin-releasing hormone (GnRH) synthesis are rapidly upregulated by the developing embryo following fertilization of the ovum. [1] [2] [3] During early embryonic development, paracrine/juxtacrine signaling of hCG induces blastulation and neurulation.
Gonadotropins are glycoprotein hormones secreted by gonadotropic cells of the anterior pituitary of vertebrates. [1] [2] [3] This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the placental/chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG), [3] as well as at least two forms of fish ...
Gonadotropic cells (also known as gonadotropes, gonadotrophs, delta cells, or delta basophils) are endocrine cells in the anterior pituitary that produce gonadotropins.More specifically, gonadotrophs produce and secrete glycoprotein polypeptide hormones, such as the follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are released due to the positive input of gonadotropin ...
In females, FSH insensitivity results in diminished development of ovarian follicles and granulosa cells and low to normal estrogen levels, elevated to very elevated gonadotropin levels, and low inhibin B levels, whereas males present with diminished Sertoli cell proliferation and moderately elevated FSH levels, normal to slightly elevated LH levels, normal testosterone levels, and reduced ...
8 Pregnancy – hCG (Human chorionic gonadotropin) 9 Testosterone 10 Testicle 11 Incentives 12 Prolactin – PRL. Two of the most significant differences between puberty in females and puberty in males are the age at which it begins, and the major sex steroids involved, the androgens and the estrogens.
In any case, the LH and FSH levels will rise in cases of primary hypogonadism or menopause, while they will be low in women with secondary or tertiary hypogonadism. [ 7 ] Hypogonadism is often discovered during evaluation of delayed puberty , but ordinary delay, which eventually results in normal pubertal development, wherein reproductive ...
