The correct option is 2 and 3 only.
Explanation
The male reproductive system comprises the testes, accessory ducts, glands, and the external genitalia. The system is designed to produce sperm and facilitate their transfer.
- Statement 1 is Incorrect: The vas deferens emerges from the cauda epididymis, ascends to the abdomen, and loops over the urinary bladder. It does not enter the kidney. It eventually joins the duct from the seminal vesicle to form the ejaculatory duct.
- Statement 2 is Correct: The urethra originates from the urinary bladder and extends through the penis to its external opening called the urethral meatus. In human males, the urethra acts as a common passage for both urine and semen (sperms).
- Statement 3 is Correct: The male accessory glands include paired seminal vesicles, a prostate, and paired bulbourethral glands. Secretions from these glands constitute the seminal plasma, which is rich in fructose, calcium, and certain enzymes. This fluid provides a fluid medium to make sperm transport easier and provides nutrition to the sperms.
Key Takeaway: The male urethra is a urogenital duct serving both the excretory and reproductive systems. The vas deferens connects the epididymis to the urethra, looping over the bladder, not the kidney.
