Language plays a central role in how gender and sexuality are described. In Bangla or Bengali, physicians, when educating and counseling women patients, do not have a socially acceptable word for “vagina”. If language is missing for female genitalia or important female sexual functions, could this absence reflect on the position of women in society, reproductive rights, and access to healthcare? Is there a relationship between language and the high rates of the gender-based cervical and breast cancers in some low and middle-income countries? This commentary examines scholarship on the topic of language, the female body, gender-based violence, disparities of healthcare for women, and the consequences of language on sexual attitudes and health.

South African indigenous bucks are raised under extensive conditions and are more likely to reject artificial vagina (AV) due to their limited contact with human beings, as they are less handled. The purpose of the study was to compare goat semen collection techniques used for goats based on semen traits of South African indigenous bucks during the natural breeding season. A total of eight South African indigenous bucks were used, four bucks per semen collection technique due to their scarcity. Before semen collection with AV group, ten bucks were trained and exposed to AV. Semen was then collected from both groups over a period of six weeks per individual buck. Semen volume, pH and sperm concentration were evaluated immediately. The Computer Aided Sperm Analysis (CASA) assessed the sperm motility rates. Sperm morphology was evaluated using a fluorescence microscope with the aid of eosin-nigrosin staining. Analysis of variance was used to test the differences among the semen collection groups following assessment by CASA. Semen collected with EE resulted in higher semen volume (1.1 mL) compared with AV (0.5 mL) technique. However, AV technique resulted in higher total sperm motility and rapid movement (91.9% and 48.7%), live sperm (72%) and sperm concentration (635.6 × 106 sperm/mL) compared with EE (86.3% and 30.4%;69% and 463.7 × 106 sperm/mL, respectively). There were no significant differences observed in pH and sperm morphology characteristics between two semen collection techniques. Moreover, EE had higher sperm moving in a progressive (53.6%) and medium rate compared with AV (41.1% and 21.9%) technique. It was concluded that the AV yielded higher total sperm motility rate, sperm concentration and rapid sperm movement compared with EE. Therefore, AV was more suitable for semen collection of South African indigenous bucks, even though training was problematic to such indigenous bucks.

With the aid of immunohistochemistry, the present review attempts to demonstrate the composite fibers and nerve topographical anatomy in the vaginal supportive tissues. Along the tendinous arch of the pelvic fasciae, distal parts of the pelvic plexus extend antero-inferiorly and issue nerves to the internal anal sphincter as well as the cavernous tissues. At the attachment of the levator ani muscle to the rectum, smooth muscles in the endopelvic fascia lining the levator ani merge with the longitudinal smooth muscle layer of the rectum to provide the conjoint longitudinal muscle coat or the longitudinal anal muscle (LAM: smooth muscle). However, at the rectovaginal interface, the longitudinal smooth muscle layer of the rectum continues to the LAM without any contribution of the endopelvic fascia. The bilateral masses of the perineal smooth muscles (PSMs) are connected by the perineal body, and the PSMs receive 1) the longitudinal anal muscle, 2) the internal and external anal sphincters and, 3) the perineal membrane lining the vestibular wall. Tensile stress from the levator ani seems to be transferred to the PSMs via the LAM. Because of their irregularly arrayed muscle fibers, instead of a synchronized contraction in response to nerve impulses, the PSMs are likely to act as a barrier, septum or protector against mechanical stress because, even without innervation, such smooth muscle fibers resist (not absorb) pressure, in accordance with Bayliss’ rule. The external anal sphincter, a strong striated muscle, inserts into the PSMs and seems to play a dynamic role in supporting the rectovaginal interface to maintain the antero-posterior length of the urogenital hiatus. However, we do not think that smooth muscles play an active traction role without cooperation from striated muscle. The fibrous skeleton composed of smooth muscle in the female perineum is explained in terms of a “catamaran” model.

Melanoma of the vagina is a rare lesion. It results from the malignant transformation of ectopic melanocytes occurring in post-menopause. The CKIT is expressed in 36% of cases in addition to melanoma markers. Prognosis is poor especially for inoperable and disseminated forms despite systemic therapy. Treatment with Imatinib is an option in cases of metastatic mucosal melanoma with CKIT mutation or amplification. We report the case of post-menopausal women, treated at Hassan II University Hospital, diagnosed with metastatic melanoma of the vagina, that didn’t respond to first line of chemotherapy, and received Imatinib as second line of treatment, with good clinical response and durable stability at radiological assessment.

In 2001, Laskin et al firstly described a series of 14 seemly distinctive mesenchymal tumors that occurred exclusively in the superficial lamina propria of the vagina and cervix of middle to old-aged women. They proposed the term ＂superficial cervicovaginal myofibroblastoma （SCVM）＂ to highlight the unique features of this tumor： the superficial subepithelial location and myofibroblastic differentiation of the minor cells. SCVM appears less well recognized with only three additional reports have been documented in the English literatures.24 In this study, we described four new cases of SCVM to further characterize the clinical and pathological features of this rare entity.

In the present study, eight strains were isolated from 20 cow vagina samples and identified using phenotype, biochemical analysis, sugar fermentation tests, and 16S rRNA sequence analysis. Among eight strains, only SQ0048 was identified as Lactobacillus johnsonii based on a series of biochemical testing (including the adhesion test, catalase test, bacteriocin production test, antibacterial test, and pH value), suggesting that its biological activity was superior to the other seven strains. Furthermore, SQ0048 had the lowest pH value (4.32) and the shortest fermentation time (8 h) compared with the other strains. The adhesion rate of SQ0048 was significantly higher than that of Lactobacillus delbrueckii, with an average adhesion number of 304 ± 2.67. The hydrogen peroxide production testing in SQ0048 was positive;in addition, bacteriocin gene of SQ0048, encoding an approximately 10-kDa product, was successfully cloned, expressed, and detected using the SDS-PAGE method. Meanwhile, SQ0048 had a weak inhibitory effect on Staphylococcus aureus and Escherichia coli. However, the expression products of the bacteriocin gene of SQ0048 had a very strong inhibitory effect on S. aureus and E. coli, with inhibition zone sizes of 18 ± 0.45 mm and 15 ± 0.60 mm, respectively. These data showed that SQ0048 has excellent antibacterial properties compared with other isolated strains and is a potential probiotic candidate to improve the health of the vaginas of cows by inhibiting pathogenic microorganisms.
