Does Female Ejaculation Serve an Antimicrobial Purpose?


Science has long been interested in female ejaculation, which is defined as the release of a viscous, white liquid from the urethra during sexual stimulation. Often called “female ejaculate,” this discharge is thought to come from Skene’s glands, or the female prostate, which are glandular tissue comparable to the male prostate. Although there is still much to learn about the functional significance of  new research points to a possible antibacterial role. Prostate-specific antigens and acidic phosphatases, which are also present in male seminal fluid, have been identified by analysis of female ejaculate. In this article, we put forth the theory that, by introducing antimicrobial substances into the urethra, female ejaculation acts as a defense mechanism against urinary tract infections (UTIs), especially those brought on by coitus.We further propose that the capacity to ejaculate glandular secretions and the preservation of prostatic tissue provide an evolutionary benefit that enhances fertility and lowers the prevalence of urinary tract infections. Anatomical, metabolic, and evolutionary factors all support this theory, which calls for more research to clarify the possible function of female ejaculation in preserving urogenital health and reproductive fitness.


Scientists and medical professionals have been fascinated by female ejaculation—the ejection of a fluid from the urethra during a sexual arousal or orgasm—for ages. The existence and content of male seminal fluid and female ejaculate have been debated, but recent studies have revealed anatomical and biochemical similarities. This has led to conjecture about the possible purposes of female ejaculation that go beyond gratification of the senses. In this paper, we put forth the theory that female ejaculation protects women against urinary tract infections (UTIs) and so enhances urogenital health and female reproductive success.Female ejaculation has long been a topic of curiosity and intrigue, with researchers and scientists seeking to understand its function and significance. Recent studies have shed light on the similarities between male seminal fluid and female ejaculate, suggesting that there may be more to this phenomenon than just pleasure. By exploring the potential role of female ejaculation in protecting against UTIs, we aim to contribute to a deeper understanding of its importance in women’s health and reproductive success.

Anatomical and Biochemical Basis of Female Ejaculation:

The anatomic basis for female ejaculation is provided by the existence of glandular tissue homologous to the male prostate, also referred to as Skene’s glands or the female prostate. These glands, which surround the urethra and are situated behind the bladder, are thought to be the source of the fluid released during female ejaculation. Prostate-specific antigens such as prostatic acidic phosphatase (PAP), prostate-specific antigen (PSA), and prostate-specific acid phosphatase (PSAP) have been identified through analysis of female ejaculate that are identical to those found in male seminal fluid. It has also been discovered that female ejaculate has a different composition from pee due to its higher glucose content and lower creatinine levels. This distinction in composition suggests that female ejaculation is a distinct physiological process separate from urination. Additionally, the presence of prostate-specific antigens in female ejaculate supports the existence of a functional female prostate, challenging traditional notions of female reproductive anatomy. 

Hypothesis: Antimicrobial Role of Female Ejaculation:

Drawing from the morphological and molecular parallels between male and female seminal fluid and ejaculate, our hypothesis is that female ejaculation acts as a conduit for the delivery of antimicrobial substances into the urethra, providing protection against urinary tract infections. UTIs are a frequent and bothersome infection among women, especially those caused by sexual activity (coitus-induced UTIs), which can cause discomfort, pain, and consequences if left untreated. Female ejaculation may aid to stop the ascent of harmful bacteria into the urinary tract, lowering the risk of UTIs, by discharging antimicrobial fluids into the urethra during sexual excitement or orgasm.This hypothesis is supported by studies that have found antimicrobial properties in the fluid released during female ejaculation. Additionally, the forceful expulsion of fluid during ejaculation may help to flush out any bacteria that may be present in the urethra, further reducing the risk of UTIs. 

Supporting Evidence and Evolutionary Considerations:

There are other lines of evidence that back up our theory. First off, it is commonly known that male seminal fluid contains antibacterial substances like zinc. Female ejaculate may also contain these same substances. Second, antibiotic secretions can be directly delivered to the location of probable infection thanks to Skene’s glands’ close proximity to the urethra. Third, a selection advantage brought about by a lower incidence of urinary tract infections and increased reproductive fitness may account for women’s evolutionary preservation of prostatic tissue and their capacity to ejaculate glandular secretions.

Implications and Future Directions:

To confirm our theory and clarify the precise antibacterial characteristics of female ejaculate, more investigation is required. Clinical research comparing the prevalence of urinary tract infections (UTIs) among women who ejaculate vs those who do not could shed light on the possible preventive effects of this practice. Furthermore, examining the molecular makeup of female ejaculate and its antimicrobial characteristics will improve our comprehension of its biological relevance. In the end, acknowledging the antimicrobial role of female ejaculation could have an impact on urogenital health promotion and the creation of innovative methods for managing and preventing UTIs.


Finally, we put forth the theory that female ejaculation functions as a conduit for the delivery of antimicrobial substances into the urethra, providing protection against urinary tract infections. Anatomical, physiological, and evolutionary factors all support this theory, which needs more research to completely understand the possible function of female ejaculation in preserving urogenital health and fostering female reproductive success. By increasing our knowledge of the physiological role of female ejaculation, we may be able to better comprehend urogenital physiology and create novel strategies for the treatment and prevention of UTIs.
