The Importance of Male Ejaculation for Female Sexual Satisfaction and Function.

INTRODUCTION: Although links between ejaculatory control or intravaginal ejaculatory latency time and female sexual functioning have frequently been reported in the past, no study has investigated the importance of other male ejaculatory characteristics, such as ejaculation volume and intensity, for women's sexuality.

AIM: To assess the importance of subjectively perceived ejaculation intensity and ejaculation volume for female sexual function and satisfaction.

METHODS: This was a cross-sectional online survey including 240 sexually active, heterosexual women (median age 27.4 years), using study-specific questions and validated questionnaires.

MAIN OUTCOME MEASURE: Results are presented as means, percentages, and age-controlled partial correlation coefficients of the main study variables.

RESULTS: 50.43% of women considered it very important that the partner ejaculates during intercourse. 18.3% of women preferred that the partner ejaculates before they reach orgasm, whereas for 53.5% this did not matter. 22.6% of women stated that they experienced a more intense orgasm when their partner ejaculated during vaginal intercourse. 17.4% reported that they definitely experienced a more intensive orgasm depending on the intensity of their partner's ejaculation, whereas for 17.8% this did not matter at all. 20.9% of women did not feel that their orgasm was more intense depending on the subjectively felt ejaculate quantity, whereas the majority (37.9%) stated that it did not matter. 13.1% of women regarded the quantity of expelled ejaculate as an expression of their own sexual attractiveness. Women stating that they experienced more intense orgasms when the partner ejaculated, when the partner experienced a more intense ejaculation, and when he expelled a greater ejaculate quantity also reported better lifelong orgasmic function (r = 0.24, r = 0.15, r = .26, respectively) and more lifelong sexual satisfaction (r = .29, r = .15, r = 26, respectively).

CLINICAL IMPLICATIONS: The perception of ejaculatory characteristics can be related to the female partner's sexual satisfaction and overall sexual functioning.

STRENGTH & LIMITATIONS: This is the very first study to explore the importance of male ejaculation volume and intensity for women's sexual functioning. Data are of self-report nature and ejaculation characteristics were not objectively measured but by women's self-report.

CONCLUSION: Although male ejaculation and its different aspects seem to play an important role for women, the study demonstrates a considerable variability of women's attitudes toward ejaculatory characteristics. Further research is required to examine the sources of this variability. Burri A, Buchmeier J, Porst H. The importance of male ejaculation for female sexual satisfaction and function.
