Sperms are produced by the process of ?

Appeared in: RRB Nsg. Superintendent-21 July 2019 (Shift-2nd)

Explanation

Spermatogenesis is the specific biological term for the process of producing spermatozoa (sperms).
This process takes place in the seminiferous tubules of the testes.
It begins with diploid (46,XY) spermatogonial cells which undergo meiotic division to form four mature, haploid (23,X or 23,Y) sperm cells.
The entire process, from stem cell to mature sperm, takes approximately 70 to 90 days.

Option B: Oogenesis is the process of producing female gametes (ova or eggs), not male gametes (sperms).
Option C: Ovulation is the release of a mature egg from the ovary. It is a single event in the menstrual cycle, not the continuous process of cell production.
Option D: Gestational is an adjective related to pregnancy (gestation), which is the period of fetal development in the uterus after fertilization.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Gametogenesis in Males as background academic context rather than a clinical decision trigger.
Understanding spermatogenesis is fundamental for assessing and managing male infertility. A semen analysis evaluates the outcome of this process (sperm count, motility, morphology).
Nurses educate patients on factors that can impair spermatogenesis, such as high fevers, exposure to toxins, certain medications (e.g., anabolic steroids), and lifestyle choices like smoking and excessive alcohol use.
Semen quality can be a biomarker for a man's overall health. Poor semen parameters have been associated with higher risks of diabetes, heart disease, and certain cancers.

How to Approach the Question

First, identify the key term in the question: 'sperms'.
Next, analyze the options provided. Look for a term that relates directly to sperm.
Use knowledge of prefixes and root words. 'Spermato-' refers to sperm, and '-genesis' means creation or production.
Combining these, 'Spermatogenesis' literally means 'sperm production'.
Eliminate the other options by defining them: 'Oogenesis' relates to 'oo-' (egg), 'Ovulation' is the release of an egg, and 'Gestational' relates to pregnancy.
