Hemorrhoids
Vascular structures in the anal canal which help with stool control. They become pathological or piles when swollen or inflamed. In their physiological state, they act as a cushion composed of arterio-venous channels and connective tissue that aid the passage of stool. The symptoms of pathological hemorrhoids depend on the type present. Internal hemorrhoids usually present with painless rectal bleeding while external hemorrhoids present with pain in the area of the anus.
Recommended treatment consists of increasing fiber intake, oral fluids to maintain hydration, NSAID analgesics, sitz baths, and rest. Surgery is reserved for those who fail to improve following these measures.

Homosexuality
Homosexuality is romantic or sexual attraction or behavior between members of the same sex or gender. As a sexual orientation, homosexuality refers to "an enduring pattern of or disposition to experience sexual, affectionate, or romantic attractions" primarily or exclusively to people of the same sex; "it also refers to an individual's sense of personal and social identity based on those attractions, behaviors expressing them, and membership in a community of others who share them."
Homosexuality is one of the three main categories of sexual orientation, along with bisexuality and heterosexuality, within the heterosexual-homosexual continuum (with asexuality sometimes considered the fourth). Scientific and medical understanding is that sexual orientation is not a choice, but rather a complex interplay of biological and environmental factors. While some religious organizations hold the view that homosexual activity is unnatural or dysfunctional, research shows that homosexuality is an example of normal variation in human sexuality and is not in and of itself a source of negative psychological effects. Prejudice and discrimination against homosexual and bisexual people, however, have been shown to cause psychological harm.
Hormones
A chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism.
Hypersexuality
See nymphomania.
Hypospadias
Hypospadias is a birth defect of the urethra in the male that involves an abnormally placed urinary meatus (the opening, or male external urethral orifice). Instead of opening at the tip of the glans of the penis, a hypospadic urethra opens anywhere along a line (the urethral groove) running from the tip along the underside (ventral aspect) of the shaft to the junction of the penis and scrotum or perineum. A distal hypospadias may be suspected even in an uncircumcised boy from an abnormally formed foreskin and downward tilt of the glans.
The urethral meatus opens on the underside of the glans penis in about 50–75% of cases; these are categorized as first degree hypospadias. Second degree (when the urethra opens on the shaft), and third degree (when the urethra opens on the perineum) occur in up to 20 and 30% of cases respectively. The more severe degrees are more likely to be associated with chordee, in which the phallus is incompletely separated from the perineum or is still tethered downwards by connective tissue, or with undescended testes (cryptorchidism).
