peenise

Peenise is not a standard anatomical term; it is a misspelling or informal variant of penis, the external male reproductive organ. The penis is involved in urination and sexual function, and its visible form typically includes a shaft and a glans, often covered by a foreskin in uncircumcised individuals. In many contexts, the conventional spelling penis is preferred in medical and educational writing.

Anatomy and structure: The penis contains two dorsal corpora cavernosa and a single ventral corpus spongiosum that houses the urethra. The glans is the expanded distal end, and the shaft connects to the body via the root. The skin over the penis can be loose, and the foreskin (prepuce) may be present or removed by circumcision. Sensation is carried by nerves in the area, including branches of the pudendal nerve, and the blood supply comes from branches of the internal pudendal arteries, with venous drainage through superficial and deep systems.

Development and function: The penis develops from the embryonic phallus, with masculinization driven by androgens such as dihydrotestosterone (DHT). At puberty, growth and increased vascular and neural innervation lead to mature sexual function. The penis functions in urination via the urethral passage and in sexual activity through erection, which is a vascular and neural process, and ejaculation, which involves coordinated muscular contractions and emission of semen.

Health and variation: Size varies widely among individuals and typically falls within a wide normal range. Common health considerations include balanitis (inflammation of the glans), phimosis (tight foreskin), Peyronie’s disease (fibrous curvature), and priapism (prolonged erection). Good hygiene, safe sexual practices, and regular medical care are important for maintaining health.
