Changes in Sexual Desire in Women and Their Partners during Pregnancy.

When studying sexual desire during pregnancy, most research focuses on the pregnant woman's sexual desire and almost never takes into account her sexual partner. The novelty of this study is that sexual desire during pregnancy is studied from the point of view of the pregnant woman and from that of her male partner. The goal of this study is to see how sexual desire behaves during pregnancy in both partners. For this, a descriptive, longitudinal, and multistage study was designed. Methodologically, in the first stage, the different study variables were described through a single-variate analysis. In the second stage, one variable was related to others by means of a bivariate analysis. Finally, in the third stage, a multivariate analysis was done, composed of binary logistic regression models and latent growth curves. The results confirm that pregnancy influences the sexual desire of both partners, and that sexual desire behaves differently in women than in men during pregnancy. Men have higher levels of sexual desire throughout pregnancy as compared to women. The first trimester of pregnancy is the period when women have less sexual desire.
