title: A clinical study on injectable contraceptive Noristerat.
abstract: Results of a clinical study involving 382 subjects using the injectable contraceptive Noristerat (norethisterone enanthate) is presented.  The maximum number of acceptors were between 21-25 years of age and had been married for 6-10 years.  50% began their 1st injection within 1 year of the last childbirth.  Continuation rates were very high and about 75% returned for their 2nd injection.  Among the users, weight gain was seen more commonly than weight loss.  There was no significant change in blood pressure.  52.2% reported a menstrual pattern which was within the acceptable range of normal, while only 12.7% had amenorrhea.  15% showed other types of menstrual disturbance.  Only 1 woman in the series became pregnant.  Menstrual abnormality was the most common cause for discontinuation among the 71 subjects available for interview.
