The test protocols are based on weights of five mandatory male reproductive tract tissues--ventral prostate (VP), paired seminal vesicles and coagulating glands (SVCG), the levator ani and bulbocavernosus muscles (LABC), the glans penis (GP), and the paired Cowper's or bulbourethral glands (COWS)--after 10 consecutive days of test substance administration to castrated male rats.
This will enable you to determine if the bulbocavernosus muscles are separated or retracted, generally from childbirth or chronic straining or constipation, and will give you an assessment of the perineal body integrity.
With the extent of the deficiency taken into account, I mobilize and dissect the mucosa with Metzenbaum scissors so that I can identify or at least attempt to palpate the ends of the retracted bulbocavernosus muscles.
The assay was later modified to assess the related myotrophic action by measuring the levator ani and bulbocavernosus muscles (LABC) (Eisenberg and Gordan 1950; Eisenberg et al.
In these laboratories, only the levator ani muscle, and not the bulbocavernosus muscle, was dissected.
An androgen-sensitive neuromuscular system that is critical for normal male copulatory behavior is the levator ani and bulbocavernosus (BC) skeletal muscles and their motor neuron control centers in the lumbar spinal cord [the spinal nucleus of the BC (SNB)].
Fused anteriorly to the posterior vaginal wall and attached laterally to the perineal membrane and bulbocavernosus and superficial transverse perineal muscles, a significant portion of what is clinically called the perineal body is actually the muscle of the external anal sphincter.
The Hershberger assay is one of the assays selected for validation based on the need for in vivo screening to detect androgen agonists or antagonists by measuring the response of five sex accessory organs and tissues of castrated juvenile male rats: the ventral prostate, the seminal vesicles with coagulating glands, the levator ani and bulbocavernosus muscle complex, the Cowper's glands, and the glans penis.
