[ XXXX --an epidemiologic study of fertility, contraception and sterility].

@entity1 @entity249 @entity6 @entity2931 @entity1009 @entity2690 @entity53 @entity7992
MATERIAL AND METHODS: Data from 672 female @entity1 with @entity6 between 17 and 42 years of age were collected by questionnaire. Mean manifestation age was 19.9 years ( @entity1009 , max. 38). RESULTS: 72.39% of the @entity1 were treated with @entity2690 ; one third had successful pregnancies. Only one of ten @entity6 delivered more than once after @entity6 had become manifest. At the time of the study, 126 (19.1%) of the @entity1 attempted pregnancy; about one-fifth of these for more than 2 years. @entity6 manifestation occurred significantly earlier in @entity1 who did not achieve conception. Correlation between daily @entity2690 dose and @entity249 was proved, whereas duration of @entity6 had no significant influence on fertility. @entity7992 was found in 0.62%, among nulliparous @entity1 1.64%, respectively. Contraception was performed in 64.2% (32.8% hormonal contraceptives, 18.6% IUD, 1.8% natural family planning, 11.0% tubal sterilisation or hysterectomy, 35.8% no contraception). 47% of the used oral contraceptives contained a reduced @entity2931 dose (30 micrograms @entity53 ). In one third of the users, IUD were longer than 5 years in place. Tubal sterilisation was found in 69 (10.44%) of @entity6 @entity1 ; in 51 cases before the age of 30 years. CONCLUSIONS: Contraceptive methods should be selected carefully. @entity6 @entity1 unsuccessfully attempting pregnancy should be referred early to a centre for reproductive medicine.
