Abstract

Previous studies have identified a number of factors that contribute to improved cognitive function, and to memory function specifically, in cognitively normal individuals. One such factor, frequency of penile-vaginal intercourse (PVI), has been reported in a number of animal studies to be advantageous to memory for previously presented objects by increasing neurogenesis in the dentate gyrus of the hippocampus. However, studies investigating the potential benefits of frequent PVI on memory function in young women are to the best of our knowledge absent from the literature. The current study thus investigated whether the self-reported frequency of sexual intercourse was related to memory function in healthy female college students. To determine whether variation in PVI would be associated with memory performance, we asked 78 heterosexual women aged 18-29 years to complete a computerized memory paradigm consisting of abstract words and neutral faces. Results showed that frequency of PVI was positively associated with memory scores for abstract words, but not faces. Because memory for words depends to a large extent on the hippocampus, whereas memory for faces may rely to a greater extent on surrounding extra-hippocampal structures, our results appear to be specific for memory believed to rely on hippocampal function. This may suggest that neurogenesis in the hippocampus is higher in those women with a higher frequency of PVI, in line with previous animal research. Taken together, these results suggest that PVI may indeed have beneficial effects on memory function in healthy young women.
