Porcine zonae pellucidae, following deglycosylation with trifluoromethane-sulfonic acid, retained significant immunogenic potential, as shown by the ability to generate antibodies which cross-reacted with the heterologous antigen. Antibody response, however, was much stronger against the native zona glycoproteins, thereby suggesting that both carbohydrate and protein moieties contribute to the overall immunogenicity of the zona pellucida antigens. Contraceptive efficacy of active immunization with the deglycosylated zona antigens, when evaluated by mating experiments, demonstrated inhibition of fertility in all immunized rabbits. Normal ovarian functions were disrupted in these animals, as revealed by the reduction in ovarian weights and gross impairment of folliculogenesis. Flushing of the oviducts of the immunized animals yielded a markedly reduced number of ova ovulated in response to hCG administration, none of which were fertilizable. Results collectively suggest that active heteroimmunization with deglycosylated zona pellucida antigens is effective in reducing fertility in rabbits.","PeriodicalId":13990,"journal":{"name":"International Journal of Fertility","volume":"37 1","pages":"53-63"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12522253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Reproductive characteristics and contraceptive method choices of Nigerian women requesting terminal fertility control.","authors":"O Fakeye","doi":"","DOIUrl":"","url":null,"abstract":"A choice of a safe and acceptable contraceptive method is an important concern for women who have completed their child-bearing intentions. This paper focuses on 557 women (mean age 35.9 years, mean number of living children 5.8 +/- 1.4, and mean number of living sons 3.1 +/- 1.3) who indicated some desire to limit childbearing, and were seen at the University of Ilorin Teaching Hospital, Family Planning Clinic in 1986/7. During this period, a wide and free choice of contraceptive methods, including the new subdermal levonorgestrel implant method (NORPLANT) and female surgical sterilization, was offered. Contraceptive method choices of women requesting terminal fertility control are: IUD 56%, injectables 15.3%, female sterilization 11.5%, pills 8.6%, NORPLANT 8.1%, others 0.5%. Comparing terminal and nonterminal contraceptors, almost equal proportions adopted the IUD, 56% vs. 60.5%, while terminal contraceptors adopted the injectables and NORPLANT in significantly higher proportions. Within subgroups by contraceptive method, mean age and mean number of living children and of sons are not significantly different, though younger women tend to adopt the pill. Method choice of NORPLANT and tubal ligation was favoured by previous contraceptive use, but not by spousal approval. Years of education had a positive influence on the choice of NORPLANT. The program implications of these findings regarding selective counselling of terminal contraceptors, provision of long-lasting reversible contraceptive methods, and facilities for surgical sterilizations for men and women are discussed.","PeriodicalId":13990,"journal":{"name":"International Journal of Fertility","volume":"37 1","pages":"19-23"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12522349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
