During a clinical study on hormone replacement therapy for pituitary gland dysfunction, patients are treated with recombinant follicle-stimulating hormone (rFSH) to stimulate follicular development.
Of the patients undergoing this therapy, only 68–84%68\text{--}84\%68–84% develop at least three mature follicles.
Of those patients who develop at least three mature follicles, only 55–72%55\text{--}72\%55–72% achieve a successful clinical pregnancy following ovulation induction.
Calculate the maximum number of patients who will achieve a successful clinical pregnancy from a group of 75 patients undergoing rFSH therapy.
Give your answer to the nearest whole number.
