Infertility and IVF Methods — NEET Biology

Correct answer: B — S1, S4, and S5 are correct.

This question assesses understanding of infertility, its causes, and the appropriate steps in its management as per NCERT. S1: Correct. NCERT states, "Inability to conceive or produce children even after 2 years of unprotected sexual cohabitation is called infertility." S2: Incorrect. NCERT states, "In India, often the female is blamed for the couple being childless, but more often than not, the problem lies in the male partner." S3: Incorrect. ARTs are generally considered when 'corrections are not possible'. Initial diagnosis and corrective treatment of underlying disorders are preferred first-line interventions, as stated by NCERT: "However, where such corrections are not possible, the couples could be assisted to have children through certain special techniques..." S4: Correct. NCERT lists multiple reasons for infertility: "The reasons for this could be many–physical, congenital, diseases, drugs, immunological or even psychological." S5: Correct. NCERT states, "Specialised health care units (infertility clinics, etc.) could help in diagnosis and corrective treatment of some of these disorders and enable these couples to have children." Therefore, statements S1, S4, and S5 are correct. The final answer is B because it accurately identifies the correct statements regarding infertility and its management.
