RRB Paramedical Staff Nurse Model Paper 1

A couple can only be said to be suffering from infertility when they have had at least a year of unprotected and regular intercourse despite which they have failed to conceive. Infertility is not to be confused with sterility which denotes the absolute inability of an individual to either, impregnate or be impregnated, under any and all circumstances. An example of this would be males with untreated cryptorchidism in whom spermatogenesis does not take place.
