Official title
Impact of Intrauterine Contraception on the Immune Environment of the Female Genital Tract
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This pilot study is being performed to investigate the influence that starting contraception with an IUD has on the local immune cell populations and features, with a particular focus on the cells and cell-surface features that are important in HIV transmission (CD4 cells and CCR5 cell receptors). Based on results from large epidemiologic studies there seems to be a consistent finding of slightly increased HIV acquisition in women who use hormonal contraception. It is not clear if this is due to a biological phenomenon or if it relates to a difference in sexual behaviors/risks of women on hormonal contraceptives. The study hypothesis is that CD4 cells and CCR5 HIV-tropic receptor density increases within the upper and lower genital tract of women 2 months after placement of progestin-containing intrauterine devices for contraception as compared with women not using hormonal contraception.
