Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

An October 1995 letter issued by the UK Medicines Control Agency warned that third-generation oral contraceptives

(OCs) containing gestodene or desogestrel may increase the risk of venous thromboembolism. The letter expressed

concern that the number of pregnancies and induced abortions would increase as a result of abrupt discontinuation

of these formulations. The validity of this concern was investigated in a retrospective review of data on cohorts of OC

users drawn from the General Practice Research Database. In the cohort of women who took OCs in the year before

October 1994, 74% of users of the third-generation OCs, and 77% of users of other OC formulations, continued use

after the 1995 warning. 4% and 8%, respectively, switched to another OC and 22% and 15%, respectively, terminated

OC use. In contrast, among the cohort that began OC use in the months prior to the October 1995 warning, 14% of

third-generation users, and 79% of other users, continued the same pill after the warning. 68% and 5%, respectively,

switched to another OC formulation; 18% and 16%, respectively, discontinued OC use. The 12-month frequencies of

pregnancies and pregnancy terminations did not differ significantly in the 1994 and 1995 cohorts in overall rates or by

type of OC, suggesting the warning was not associated with the feared abrupt termination of OC use and upswing in

unwanted pregnancies. (PubHealth.info Document ID: CONT2T 48-06)
