Q11(b):
State True/False with explanation
(b) Infertility is defined as the inability to produce a viable offspring and is always due to abnormalities/defects in the female partner. (True/False)
Solution :
Statement Analysis
The statement provided is: False.
Step 1: Scientific Definition of Infertility
Infertility is clinically defined as the inability of a couple to conceive or produce a viable offspring after at least one year of regular, unprotected coitus. [Reference: WHO/ICMR standard clinical diagnostic criteria for infertility].
Step 2: Addressing the Etiology of Infertility
The assertion that infertility is always due to defects in the female partner is scientifically inaccurate. Research indicates that the causes of infertility are multifactorial and can be attributed to either partner, or both simultaneously. Statistical distribution of fertility factors typically follows this breakdown:
| Factor Origin | Contribution to Infertility |
|---|---|
| Male Factor | Approximately 30-40% |
| Female Factor | Approximately 40-50% |
| Combined/Unexplained | Remaining Percentage |
Step 3: Physiological Justification
- Male Factor: Infertility in males may arise from oligozoospermia (low sperm count), asthenozoospermia (low sperm motility), or teratozoospermia (abnormal sperm morphology), often caused by hormonal imbalances or blockages in the vas deferens.
- Female Factor: Infertility in females may result from ovulatory dysfunction, fallopian tube blockages, or uterine fibroids.
- Sociological Context: Due to societal conditioning, women are disproportionately blamed for infertility in many cultures; however, reproductive biology confirms the necessity of both healthy gametes and a functional reproductive tract from both partners for successful conception.
Visual Representation of Infertility Causality
Final Solution: The statement is False. Infertility can result from abnormalities in the male partner, the female partner, both partners, or other unexplained factors; it is not exclusively associated with the female reproductive system.
