Male Reproductive System | Anatomy & Physiology | Part-1 | Scrotum & Testis Structure and Functions
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 Fertility mechanisms Hormonal regulation Common clinical conditions Perfect for exams such as MBBS, BSc Nursing, GNM, NEET, paramedical courses, biology board exams, and medical practicums. 🧑⚕️ Who Should Watch?
