459 Indian female patients between the ages of 16 and 50. attending the practice of the researcher were asked to complete a confidential questionnaire on the knowledge and utilisation of contraception. The results of the study revealed that the majority of the participants were literate and possessed some knowledge of contraception. The contraceptive choice was the Pill with many participants also favouring the use of the intra uterine device. Condoms were used by only ten percent of the group while the use of the injection - Depot Provera - was negligible. Most peri menopausal women had completed their families and had undergone Tubal Ligation even though a fair number had the intra uterine device in place and also had continued using the Pill as their contraceptive. / Theses (M.Fam.Med.)-University of Natal, Durban 1995.

Five studies examined the possible influence of the sexual double standard on women's contraceptive behavior via sexual attitudes and social norms. In Study 1, longitudinal diary data from a community sample of 62 women showed that women's contraceptive behavior in ongoing sexual relationships was quadratically associated with sexual attitude. Study 2 showed that contraceptive behavior in initial and ongoing sexual encounters differed significantly in a sample of 52 university women. In initial encounters there was a greater reliance on condoms and a greater risk of unprotected intercourse. Studies 3, 4 and 5 used a person perception paradigm to examine women's perceptions of a female contraceptive provider in an initial sexual encounter. In Study 3, 57 women rated a female condom provider in a casual encounter as less nice, less socially acceptable, and her behavior as less appropriate than when her partner provided a condom. However, the target was rated as less wise if she had unprotected intercourse. In Study 4 (N = 249), a pill condition was added and the influence of sexual attitudes was assessed. Relative to when her partner provided a condom, women rated the target as less wise and less nice if she was on the pill, but they rated her as more wise when she provided a condom. Negative sexual attitudes were associated with more negative reactions but generally did not interact with contraceptive condition. In Study 5, 96 women rated the target as a function of who provided a condom (her vs. him) and four properties of the romantic relationship. Providing a condom did not result in negative evaluations in a committed relationship. In a non-committed relationship, when the woman provided a condom she was perceived as less nice but more wise. Furthermore, women used intimacy as a cue for commitment, but did not perceive intimacy alone as adequate justification for intercourse. The results of these five studies suggest that social norms may exist which discourag

Immunocontraception, or contraception mediated by the immune system, is being widely studied as an alternative, humane form of population control. The induction of an immune response against a specific component of the mammalian oocyte, termed zona pellucida (ZP) has been shown to be an effective immunocontraceptive in several species. Comparatively little work has been done investigating the use of ZP antigens in the domestic cat. This study aimed to investigate porcine ZP(B+C) and feline ZPA, B and C as immunogens in the domestic cat, and further to elucidate their effects on reproduction. Immunisation of female cats with porcine ZP(B+C) failed to elicit a detectable antibody response as assessed by ELISA, immunoblotting and immunohistochemistry. Additionally, there was no effect on the structure of the ovaries nor on breeding performance. Feline ZPA, B and C were cloned into the pkCMVint.polyli mammalian expression vector and used to immunise female cats. ELISA revealed that immunisation with either pkCMVint.fZP(B+C) or pkCMVint.fZPA DNA (Treated) resulted in a low-level circulating antibody response, which was apparently short-lived. Immunoblotting did not reveal any common pattern of recognition of antigenic polypeptides between responding animals. Ovaries from fZP Treated animals, however, showed antibody binding specifically on the ZP of follicles from late primary / early secondary, through to antral stages. Despite the antibody binding, the overall structure of the ovaries remained unaffected in all but two of the fZP Treated cats. Two fZPA immunised cats exhibited ovaries that had no recognisable follicular structures, however, the observed abnormalities could not be conclusively linked to fZPA immunisation. Overall, a significant lymphoproliferative response was shown in fZP Treated cats when compared with Controls. Fertility was not significantly affected in fZP Treated cats, although there was a tendency towards increased incidence of unsuccessful matings or pregnancies. The fZP DNA preparations studied here exhibit potential as an immunocontraceptive, with the ability to generate a lymphoproliferative response against fZP and elicit antibodies specifically recognizing fZP in situ. Further studies should continue to investigate the immunogenicity of, and characterise the immune response against, such fZP DNA preparations.
