The bulbospongiosus also functions to compress the urethra to help expel semen during ejaculation. This muscle extends between the ischium of the hip bone and the crura of the penis or of the clitoris in males and females, respectively. In females, it originates from the perineal body and is inserted into on the dorsal surface of the corpora cavernosa of the clitoris. In males it also aids in the final stages of erection by compressing the veins within the bulb of the penis to maintain tumescence. In this study, 24 male Wistar albino rats were used. 2006;27:3819. Ischiocavernosus is a bilateral, perineal muscle located in the superficial perineal space of the urogenital triangle.It is a part of the superficial group of perineal muscles, together with bulbospongiosus and superficial transverse perineal muscles..
