ejaculated

Ejaculated is the past tense and past participle of the verb ejaculate. In humans, ejaculation refers to the expulsion of semen from the penis during sexual climax and is a normal component of male reproductive function. The process is typically associated with orgasm and results from coordinated autonomic and somatic nerve activity, pelvic floor muscle contractions, and glandular secretions.

Physiology: Ejaculation generally involves two phases: emission and expulsion. During emission, sperm from the testes mix with fluids from the seminal vesicles, prostate, and other glands to form semen that collects in the posterior urethra. Expulsion then occurs as rhythmic contractions of pelvic floor muscles propel semen through the urethra and out of the body.

Semen composition: Semen consists mainly of fluids from accessory glands, with spermatozoa contributing a smaller proportion. The exact composition can vary among individuals and over time.

Timing and variability: The timing of ejaculation varies widely among individuals and circumstances. A refractory period commonly follows ejaculation, during which sexual arousal and erection are not immediately possible.

Clinical context: Ejaculatory function can be affected by medical conditions (diabetes, neurological disorders), medications (certain antidepressants and antihypertensives), age, and psychological factors. Common disorders include premature ejaculation (early onset of ejaculation relative to penetration or desire), delayed ejaculation (prolonged time or difficulty achieving ejaculation), and anejaculation (inability to ejaculate). Evaluation may involve medical history, physical examination, and targeted testing; treatment can include behavioral strategies, counseling, medications, or management of underlying conditions.
