Here are 35 multiple-choice questions, flashcards, and case questions to help you learn from the video.

Embryology of the Male Reproductive System

The male reproductive system develops from the intermediate mesoderm and the genital ridge. The testes originate from the primitive gonads, which descend from the abdominal cavity into the scrotum during fetal development. Congenital anomalies can occur during this process, such as cryptorchidism (undescended testes) and hypospadias (abnormal location of the urethral opening).

Here are some multiple-choice questions, flashcards, and case questions to help you learn from the video.

Hormonal Regulation and Feedback Loops

The hypothalamic-pituitary-gonadal axis regulates the function of the male reproductive system. Gonadotropin-releasing hormone (GnRH) from the hypothalamus stimulates the anterior pituitary to secrete FSH and LH. FSH acts on the Sertoli cells in the seminiferous tubules to support spermatogenesis, while LH stimulates the Leydig cells to produce testosterone.

Testosterone, the primary male sex hormone, is responsible for the development and maintenance of male secondary sexual characteristics, as well as the support of spermatogenesis. It acts through the androgen receptor, a nuclear receptor that regulates gene expression. Negative feedback loops involving testosterone, FSH, and LH help maintain homeostasis within the male reproductive system.

Male Reproductive Pathology

Several disorders can affect the male reproductive system, leading to infertility, sexual dysfunction, or other health problems. Some common testicular disorders include:

• Varicocele: Dilation of the veins in the scrotum, which can impair sperm production and quality.

• Testicular torsion: A medical emergency in which the spermatic cord becomes twisted, cutting off blood supply to the testis.

• Testicular cancer: Malignancies arising from germ cells, such as seminoma and non-seminoma tumors.

Prostate disorders are also prevalent, particularly in older men:

• Benign prostatic hyperplasia (BPH): Non-cancerous enlargement of the prostate gland, which can cause urinary symptoms.

• Prostatitis: Inflammation of the prostate gland, often due to bacterial infection.

• Prostate cancer: The most common cancer in men, typically affecting older individuals.

Erectile dysfunction, the inability to achieve or maintain an erection sufficient for sexual intercourse, can have various causes, including vascular, neurological, and psychological factors. Male infertility can result from hormonal imbalances, obstructive issues (e.g., blocked vas deferens), or genetic abnormalities affecting sperm production or function.

Here are some multiple-choice questions, flashcards, and case questions to help you learn from the video.

Pharmacology Related to the Male Reproductive System

Several pharmacological agents target the male reproductive system for therapeutic purposes:

• Testosterone replacement therapy: Used to treat hypogonadism and other conditions associated with low testosterone levels.

• 5-alpha reductase inhibitors (e.g., finasteride): Prescribed for the treatment of BPH and male pattern baldness, as they block the conversion of testosterone to dihydrotestosterone (DHT).

• Phosphodiesterase-5 inhibitors (e.g., sildenafil): Used to treat erectile dysfunction by increasing blood flow to the penis.

• Gonadotropins (e.g., hCG, FSH): Administered to stimulate testicular function and spermatogenesis in cases of hypogonadotropic hypogonadism or infertility.
