Ostrzenski concludes in his recent paper "G-Spot Anatomy: A New Discovery" [1] that his observation might impact on the practice and clinical research in the discipline of female sexual function. In the last few decades, there have in fact, been several studies relevant to the so-called "G-spot"-more accurately, the posterior part of the female prostate.At the 15 th World Congress of Sexology, Ablin, Zaviacic, and Eichel synthesized their independent and collaborative studies in their presentation "A natural anatomic design (c.a.t.) for coital orgasm: Implication for health and pathology" . In fact, Zaviacic [3] had previously corrected the earlier G-spot research, by identifying the anterior meatal segment of the female prostate as having the greatest concentration of prostatic tissue. Subsequently, Zaviacic, in collaboration with Ablin [4] and Eichel [2], brought attention to the part of the prostate that was a primary erogenous zone, emphasizing that it is not a vestigial organ. That segment of the female prostate was identified by Eichel as the sensory arm of the vaginal part of the blended (clitoral-vaginal) coital orgasm; and it was Eichel, who introduced the Coital Alignment Technique (CAT) that provided simultaneous clitoral and vaginal stimulation, indicating a natural anatomic design-a biological optimum .
