AbstractSix new species of Rhigonema are described from the gut of various African diplopods. Rhigonema fecundum sp. n., from South Africa, is characterised by medium to fairly long body length, finely pilose anterior region, posterior margin of cephalic collar smoothly fused to body contour, Type 2 genital tract with a long ovejector, presence of a long, closely adpressed, vulval flap, tail shape in both sexes, broad spicules of medium length and complement of 23 copulatory papillae of which three pairs are subdorsal or sublateral in position. Rhigonema oxydesmi sp. n., from Oxydesmus platycercus concolor, Zaire, is characterised by medium body length, slightly projecting cephalic collar, finely pilose anterior region, Type 2 female genital tract with a long ovejector, presence of a short, adpressed, vulval flap, tail shape in both sexes, medium length spicules with a hamate capitulum and complement of 23 copulatory papillae, three pairs of which are subdorsal or sublateral in position. Rhigonema peziphorum sp. n., from Sphaerotherium selindum, Zimbabwe, is characterised by medium body length, prominently projecting cephalic collar, finely pilose anterior region, Type 1 female genital tract with a medium length ovejector, rather large eggs, absence of a prominent vulval flap, presence of a spermatophore, tail shape in both sexes, unusually short spicules with a weakly hamate capitulum and complement of 23 copulatory papillae. It is the only known Rhigonema species to form a spermatophore. Rhigonema rostrellum sp. n., from Ivory Coast, is characterised by medium body length, finely pilose anterior region, Type 2 genital tract with a very long ovejector, presence of a closely adpressed vulval flap, tail shape in both sexes, broad spicules of medium length and complement of 23 copulatory papillae of which three pairs are subdorsal or sublateral in position. Rhigonema spicatum sp. n., from Congoromus flabellatus, Zaire, is characterised by medium body length, slightly projecting cephalic collar, densely pilose anterior region, Type 2 female genital tract with a long ovejector, presence of an adpressed vulval flap, tail shape in both sexes, relatively short spicules with a hamate capitulum and complement of 23 copulatory papillae. Rhigonema xiphiurus sp. n., from Oxydesmus sicarius, Zaire, is characterised by medium body length, projecting cephalic collar, coarsely pilose anterior region with bristly microtrichs, microtrichs extending down body to beyond vulval level in female and a similar relative position in the male, Type 2 female genital tract with a long ovejector, elongate female tail, convex conoid male tail with an exceptionally well developed subulate projection, very short spicules and disposition of the 23 copulatory papillae, three pairs of which are dorsal or sublateral in position. A synopsis of the other eight nominal species of African Rhigonema is appended.

Abstract Traditionally, the finding of semen, that is, spermatozoa and acid phosphatase, in cervicovaginal specimens has been considered the laboratory evidence needed to prove recent sexual contact. Recent research with fluorescence in situ hybridization (FISH) has shown that in the absence of semen, male epithelial and inflammatory cells can be found within the female genital tract. A striking paucity of literature exists pertaining to the examination of the penis of an alleged assailant for potential evidence indicative of sexual assault. The current study uses FISH to analyzepostcoital swabs of the penis for such laboratory evidence. A male and female volunteer couple consented to participate in this study. Following coitus, the male partner presented to one of the investigators for penile swabbing. Swabs were taken at varying postcoital intervals (1–24 hours) subsequent to 10 coital episodes. The male participant was instructed not to shower following coitus, but to otherwise go about daily activities until specimen collection. To obtain each sample, 4 sterile cotton-tipped applicators were slightly moistened in sterile saline and swabbed along the length of the penile shaft and around the base of the penis. From the swabs, 3 air-dried slides were prepared, coded, and blinded. As controls, swabs were taken from the buccal surfaces of both volunteers. Multicolor FISH was performed using dual X- and Y-chromosome probes, and slides were counterstained with 4′-6-diamidino-2-phenylindole (DAPI). Cells were easily visualized under a fluorescent microscope, but only cells with 2 nonoverlapping fluorescent signals were counted. Fluorescence in situ hybridization is highly sensitive and specific, and the dual probes easily distinguished between male and female cells. Female cells were identified on smears from every penile swab over the entire 1- to 24-hour postcoital interval. The FISH technique, previously successful in identifying male cells within the female genital tract, may also be employed on penile swabs. Once the presence of female cells is confirmed by FISH, the identity of the female can be confirmed by DNA analysis. Potentially, with such current molecular analyses, both the assailant and the victim can be positively identified.

The calcium channel of sperm (CatSper) is essential for sperm hyperactivated motility and fertility. The steroid hormone progesterone activates CatSper of human sperm via binding to the serine hydrolase ABHD2. However, steroid specificity of ABHD2 has not been evaluated. Here, we explored whether steroid hormones to which human spermatozoa are exposed in the male and female genital tract influence CatSper activation via modulation of ABHD2. The results show that testosterone, estrogen, and hydrocortisone did not alter basal CatSper currents, whereas the neurosteroid pregnenolone sulfate exerted similar effects as progesterone, likely binding to the same site. However, physiological concentrations of testosterone and hydrocortisone inhibited CatSper activation by progesterone. Additionally, testosterone antagonized the effect of pregnenolone sulfate. We have also explored whether steroid-like molecules, such as the plant triterpenoids pristimerin and lupeol, affect sperm fertility. Interestingly, both compounds competed with progesterone and pregnenolone sulfate and significantly reduced CatSper activation by either steroid. Furthermore, pristimerin and lupeol considerably diminished hyperactivation of capacitated spermatozoa. These results indicate that (i) pregnenolone sulfate together with progesterone are the main steroids that activate CatSper and (ii) pristimerin and lupeol can act as contraceptive compounds by averting sperm hyperactivation, thus preventing fertilization.
