Concept
The prostatic urethra is a segment of the male urethra that passes through the prostate gland, playing a crucial role in both the urinary and reproductive systems. It is responsible for transporting urine from the bladder to the outside of the body and also serves as a conduit for semen during ejaculation.
Relevant Fields:
Concept
The male reproductive system is responsible for producing, maintaining, and transporting sperm and protective fluid (semen), as well as discharging sperm within the female reproductive tract during sex. It also produces male sex hormones that maintain the male reproductive system and influence secondary sexual characteristics.
Concept
The urinary system is essential for removing waste products and excess substances from the bloodstream, maintaining a stable internal environment through the regulation of fluid and electrolyte balance. It consists of organs such as the kidneys, ureters, bladder, and urethra, which work together to filter blood, produce urine, and expel it from the body.
Concept
The prostate gland is a small, walnut-sized organ in males that plays a crucial role in the reproductive system by producing seminal fluid, which nourishes and transports sperm. Its health is vital, as conditions like benign prostatic hyperplasia and prostate cancer can significantly impact quality of life and require medical attention.
Concept
Ejaculation is a physiological process involving the expulsion of semen from the male reproductive system, typically occurring as a result of sexual stimulation. It is a complex reflex action that involves coordination between the nervous system and various muscles, playing a crucial role in reproduction and sexual health.

Concept
Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland, commonly affecting older men, leading to urinary symptoms such as difficulty in starting urination and increased frequency. It is caused by hormonal changes and can be managed through lifestyle modifications, medications, or surgical interventions depending on severity.
Concept
Prostatitis is an inflammation of the prostate gland, often causing painful urination and pelvic pain, and can be classified into acute bacterial, chronic bacterial, chronic prostatitis/chronic pelvic pain syndrome, and asymptomatic inflammatory prostatitis. Diagnosis typically involves a combination of patient history, physical examination, and laboratory tests, and treatment varies depending on the type, ranging from antibiotics to pain management strategies.
Concept
Urethral stricture is a narrowing of the urethra caused by injury, infection, or inflammation, leading to obstructed urine flow and potential complications like urinary retention or infection. Treatment options vary from minimally invasive procedures to surgical reconstruction, depending on the severity and cause of the stricture.
Concept
Urinary retention is the inability to voluntarily urinate, which can be acute or chronic and may lead to serious complications such as bladder damage or infection. It is often caused by an obstruction, nerve problems, or medication side effects, and requires prompt medical evaluation to determine the underlying cause and appropriate treatment.
Concept
The prostate gland is a walnut-sized exocrine gland in the male reproductive system, located just below the bladder and in front of the rectum, which plays a crucial role in producing seminal fluid that nourishes and transports sperm. Its anatomy includes distinct zones, such as the peripheral, central, and Transitional Zones, each with specific functions and clinical significance, particularly in the context of prostate health and disease.
