Study Notes
Overview of Reproductive System
- Reproduction is the biological process of producing new individuals, ensuring species growth in favorable conditions.
- It is fundamental to living organisms and essential for species continuation.
External Structures
-
Scrotum: A pouch of skin that hangs from the lower abdominal region, protecting and regulating the temperature of the testes.
- Divided into two chambers housing a testis, epididymis, and seminal ducts.
- Functions:
- Produces gametes (egg and sperm).
- Transports and sustains gametes.
- Nurtures developing offspring.
- Produces hormones.
Male Reproductive System
- The male reproductive system produces androgen, regulating male reproductive functions.
-
Penis: A cylindrical organ positioned anterior to the scrotum responsible for transferring sperm to the vagina.
- Composed of two corpora cavernosa and one corpus spongiosum, containing the urethra for urine and sperm expulsion.
- Erection is triggered by the parasympathetic nervous system, with blood supply from the penile artery.
- Features the glans (sensitive tip) and prepuce (foreskin).
Internal Structures
-
Testes (Male Gonads): Ovoid organs responsible for spermatogenesis, measuring approximately 5cm x 3cm.
- Contains interstitial (Leydig) cells, responsible for male sex hormone production.
Hormones in Male Reproductive System
- Follicle-stimulating hormone (FSH): Stimulates spermatogenesis.
- Luteinizing hormone (LH): Promotes testosterone production.
- Testosterone: An androgen vital for developing and maintaining male secondary sexual characteristics.
Circumcision
- Surgical removal of the prepuce, offering potential health benefits:
- Easier hygiene maintenance.
- Reduced urinary tract infections risk.
- Lower sexually transmitted infections risk.
- Prevention of penile complications.
