Sex hormone-binding globulin (SHBG) or sex steroid-binding globulin (SSBG) is a glycoprotein that binds to androgens and estrogens.When produced by the Sertoli cells in the seminiferous tubules of the testis, it is called androgen-binding protein (ABP).
Proceptivity and receptivity in the female rat are indicators of sexual motivation, thus indicating a direct relationship between estrogen levels and sexual motivation. In addition, female rats receiving doses of estrogen and progesterone were more likely to exert effort at gaining sexual attention from a male rat. [17]
A steroid hormone is a steroid that acts as a hormone.Steroid hormones can be grouped into two classes: corticosteroids (typically made in the adrenal cortex, hence cortico-) and sex steroids (typically made in the gonads or placenta).

Across multiple species and in some cases across sexes, there is evidence for the phylogenetic conservation of parental hormones. These include the relationships between the hormones estrogen, progesterone, prolactin, and oxytocin. In males across species, including humans, increased prolactin levels are associated with fatherhood.
The results for INAH3 weight were similar to those for INAH3 size; that is, the INAH3 weight for the heterosexual male brains was significantly larger than for the heterosexual female brains, while the results for the gay male group were between those of the other two groups but not quite significantly different from either.

Testosterone is the primary male sex hormone and androgen in males. [4] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
In general, androgens are considered "male sex hormones", since they have masculinizing effects, while estrogens and progestogens are considered "female sex hormones" although all types are present in each sex at different levels. [6] Sex hormones include: Progestogens. Pregnenolone → Progesterone → Allopregnanedione → Allopregnanolone
