Question

All of the following statements are true regarding azoospermia except
a. Pretesticular etiologies of azoospermia are usually endocrine in nature.
b. Testicular cause of azoospermia is also known as primary testis failure.
c. Secondary testis failure is characterized by high serum gonadotropin levels and small testis size.
d. Low volume azoospermia with normal testis size and palpable vas is a common presentation for testicular failure.

Answer 1

Hint: Azoospermia is a medical condition in males, whose semen contains no sperm. It causes infertility in males. A lack of sperm in the ejaculate can be indicative of blockage of the male genital system. Two conditions such as obstructive azoospermia, in which with completely normal sperm production or the result of poor sperm production, and non-obstructive azoospermia, which interferes with the production of sperm.

Complete answer:
Azoospermia, in a man whose semen contains no sperm. It is associated with infertility. In this condition, men with a low semen volume (complete absence of sperm in semen) and normal-sized testes can be caused by ejaculatory dysfunction.

The pre testicular causes of azoospermia are endocrine abnormalities. These adversely affect spermatogenesis. Testicular etiologies involve intrinsic disorders of spermatogenesis inside the testes.

Primary testicular failure (PTF) is a condition where testes don’t produce sperm despite having adequate hormonal support. Primary testicular failure is a major cause of non-obstructive, obstructive azoospermia, and oligospermia.

Hence, low volume azoospermia with normal testis size and palpable vas is a common presentation for testicular failure is false.
So, the correct answer is option (D).

Note: Other causes of testicular failure are certain medicines, including glucocorticoids, ketoconazole, chemotherapy, and opioid pain medicines. Some causes of azoospermia are certain genetic conditions such as Klinefelter's syndrome, recreational drugs such as some narcotics, and abnormalities such as varicoceles or absence of the vas deferens on each side.
