Which of the following is NOT true about testes.

Appeared in: RRB Staff Nurse Ahmedabad-2015

Explanation

  • This statement is false because the formation, development, and liberation of ova (eggs) is the function of the ovaries, the primary reproductive organs in females.
  • The primary functions of the testes are spermatogenesis (the production of spermatozoa or sperm) and the secretion of male sex hormones like testosterone.
  • Ova and spermatozoa are the female and male gametes, respectively, produced in separate and distinct organs (ovaries and testes).

Why Other Options Were Wrong

  • Option A: This is a true statement. The primary gametogenic function of the testes is to produce spermatozoa (sperm) within the seminiferous tubules.
  • Option B: This is a true statement. The testes are the primary male sex organs (gonads) and are classified as internal genitalia, although they descend into the external scrotum.
  • Option D: This is a true statement. The testes (specifically the Leydig cells) produce testosterone, the hormone responsible for the development and maintenance of male secondary sexual characteristics.

  • Visual 2: Illustration: The process of spermatogenesis within the seminiferous tubules of the testis, showing the development from spermatogonia to mature spermatozoa.
Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Functions of the male reproductive system (testes) as background academic context rather than a clinical decision trigger.
  • Understanding the distinct functions of the testes is crucial for assessing male reproductive health, including issues of infertility and hormonal imbalances.
  • Nurses educate patients on testicular self-examination (TSE) for the early detection of masses or changes that could indicate testicular cancer.
  • Cryptorchidism (undescended testes) is a significant condition identified in newborns that requires monitoring and potential intervention to preserve fertility and reduce cancer risk.
How to Approach the Question
  • First, identify the negative keyword 'NOT' in the question stem. This signals that you must find the statement that is false.
  • The subject of the question is the 'testes'. Recall the main functions of this organ.
  • Evaluate each option for its factual accuracy:
  • Option A: Do testes make sperm? Yes, this is spermatogenesis.
  • Option B: Are testes internal genital organs? Yes, they are the primary gonads.
  • Option C: Do testes make ova? No, ova (eggs) are made in the ovaries.
Concept Tested & Keywords
  • Concept Tested: Functions of the male reproductive system (testes)
  • Stem keywords: testes
  • Lead-in keywords: NOT true
  • Negative lead-in flag: Question asks for the INCORRECT statement (NOT true).
