Male Reproductive System | Anatomy & Physiology | Part-1 | Scrotum & Testis Structure and Functions

Описание: Welcome to this comprehensive lecture on the Male Reproductive System, with an in-depth explanation of the Scrotum and Testis. This video is designed for medical, nursing, paramedical, and biology students, offering clear concepts, clinical correlations, and exam-oriented points.

🧬 What This Video Covers

🔹 Male Reproductive System Overview

Primary and accessory reproductive organs
External and internal genitalia
Pathway of sperm transport
Accessory glands (seminal vesicles, prostate, bulbourethral glands)
Semen composition and ejaculation mechanism

🔹 Scrotum – Anatomy & Functions

Location and external features
Layers of the scrotum (skin, dartos, fasciae, cremasteric muscle, tunica vaginalis)
Blood supply, lymphatic drainage & nerve supply
Thermoregulation of testes (cremaster reflex, pampiniform plexus)
Clinical notes: hydrocele, varicocele, epididymitis, scrotal swelling

🔹 Testis – Anatomy & Physiology in Detail

Gross anatomy and coverings of the testis
Internal structure: lobules, seminiferous tubules, rete testis, efferent ductules
Spermatogenesis step-by-step
Sertoli cells – structure, function, hormonal role
Leydig cells – testosterone synthesis
Hormonal regulation of testicular function (Hypothalamus–Pituitary–Gonadal axis)
Descent of testis & clinical relevance (cryptorchidism, torsion, infertility)

📚 Why This Topic Is Important

Understanding the scrotum and testis is essential for learning:
Reproductive physiology
