Male insects with large weapons such as horns and elongate mandibles would be expected to invest more on such structures than other parts of the body for advantages in male to male competition for mating. In male genitalia, however, intermediate size provides a better fit for more females than small or large sizes, and such a male would leave more offspring regardless of their body size. These predictions were tested using a static allometry analysis between body size and other trait sizes. Acanthacorydalisasiatica is a large dobsonfly (Megalotera) and males have conspicuously large mandibles used as weapons. We examined the hypothesis that the male mandibles of this sexually dimorphic species are sexually selected to enlarge, whereas the male genitalia are stable to be intermediate regardless of a great variation in body size. The results, as predicted, showed positive allometry between male body size and mandible length but negative allometry between male body size and ectoproct length (a male grasping structure). Sperm are transferred through a small spermatophore attached externally to the female genital opening, so it may be evolutionarily unnecessary to develop an enlarged male genital size. In contrast, there may be a trade-off between male mandible size and wing length, because of negative allometry between body size and wing length in males but isometry between them in females.

Males of many Psylloidea are known to possess a characteristic structure at the functional hub of their reproductive apparatus, between afferent and efferent passage of seminal fluid. The structure is a squat, cylindrical endoskeleton consisting of two sections. Classical authors named them as 'sperm pump' and 'ejaculatory duct', based on superficial resemblance to a spring-loaded, thimble-shaped cylinder, encircled by smooth, vertical columns interpreted to be muscles which, when contracted, compress the cylinder and affect seminal fluid discharge. The discovery of numerous spherules of unknown composition and function in and around the columns of the Asian citrus psyllid male genitalia invoked rigorous scrutiny of the classical literature for evidence to support its claims, and determined that the grounds for vetting the structure as a sperm pump were fully teleological. This paper raises several objections to modern acceptance of this classical interpretation, presenting them as problematic, thought-provoking, and sometimes controversial anatomical features. The two sections are herein called 'drum' and 'spout'. As an endoskeleton, the sections are an invagination of the exoskeleton and therefore cannot receive seminal fluid into their hollow. A phallus is identified inside an aedeagal tube, indicating that it is the ejaculatory duct-the tube, drum, and spout are considered its housing. A sheath envelopes the drum and is directly continuous with the spout hypodermis, another problematical feature raising the question of whether it is detached from adherence to the drum cuticles. Also, there are four afferent tubes but only two openings in the drum to receive their seminal fluids.
- Gender destinies: assigning gender in Disorders of Sex Development-Intersex clinics. [Journal Article]

Based on audio recordings of consultations in three U.S. paediatric multidisciplinary Disorders of Sex Development-Intersex clinics, we examine the process of gender assignment of children with "atypical" genitalia. Rather than fully determined by the presence of biological sex traits, the gender assignment discussion hinges on how clinician and parent collaboratively imagine different aspects of what constitutes being a gendered person. They orient towards the potential for sexual intimacy, fertility, gender dysphoria, stigma, and gonadal cancer risk. While these futures remain inherently uncertain, clinicians and parents plan to mobilise gender socialisation and medical interventions to render their choice of gender a self-fulfilling prophecy. Gender destinies capture that the child always had a specific, innate gender awaiting discovery, and presumes a project for medical and social monitoring, intervention, correction, and optimisation.
- Persistent cloaca and caudal duplication in a monovular twin, a rare case report. [Journal Article]
- IJInt J Surg Case Rep 2019 Jun 12; 60:137-140
- CONCLUSIONS: Theories of etiology include failure of regression of Kovalevsky's canal (a communication that connects the amniotic and yolk sac), an incomplete form of twinning through iatrogenic damage to the zona pellucida or a failed triplet formation from a single embryo.Caudal duplication with persistent cloaca and vestigial appendage is a rare and complex malformation. Having a unified surgical and medical team to preserve quality of life and to treat complications is of key importance.
- Spiny rat SRY lacks a long Q-rich domain and is not stable in transgenic mice. [Journal Article]
- DDDev Dyn 2019 Jun 20
- CONCLUSIONS: Overall, these results support a previous study demonstrated a long Q-rich domain plays essential roles in protein stabilization in mice. Therefore, the original aim of this study, to examine the function of the Sry gene of this species, was not achieved by creating TG mice. This article is protected by copyright. All rights reserved.
- Identification of gene variants in 130 Han Chinese patients with hypospadias by targeted next-generation sequencing. [Journal Article]
- MGMol Genet Genomic Med 2019 Jun 20; :e827
- CONCLUSIONS: Higher frequency mutations were identified in SRD5A2 (52%) and AR (24%) in our patient cohort. Middle or posterior hypospadias with micropenis may be significant indicators of genetic variations. Polygenic inheritance may be a rare genetic cause of hypospadias.
- The impact of CYP21A2 (P30L/I172N) genotype on female fertility in one family. [Journal Article]
- EJEur J Med Res 2019 Jun 19; 24(1):21
- CONCLUSIONS: Despite significant improvements over the last years in achieving fertility in female patients with SV CAH, it is highly dependent upon the severity of virilization and the metabolic control. The role of P30L mutation in infertility and unsuccessfully assisted reproduction remains to be elucidated.

The female genital tracts harbor a wide variety of microorganisms' knowns as microflora mostly constituted by lactobacilli, involved in the healthy state of the vagina without causing infection. Urinary tract infections (UTI) are frequent in pregnant women due to physiological and anatomical changes that occur during pregnancy. These infections can result to disabilities or serious health problems both for the mother and the new-born. Vaginal douching has been reported among risky practices associate with UTIs. However, this remains debatable and contradictory when other studies report the benefit effects of vaginal cleaning in infection prevention. The aim of this study was to assess pregnant women behaviors and practices regarding genital hygiene. This was a cross sectional descriptive study conducted on exhaustive sample of pregnant women coming for antenatal visits in Lafé Sub-divisional Hospital (SDH) and Baleng Catholic Health Center (BCHC) between 16 and 30 September 2013. Data were collected using a paper based standardized questionnaire directly self-administered after obtain a free consent. Overall, 80 pregnant women were enrolled. The majority of them had attended at least primary education (97.5%; n=78/80) and many were lived in couple (81.25%; n=65/80). Almost one on three participants identified antenatal consultation (ANC) as a key element to be taken into account by pregnant women. 70.1% (n=56/80) of women declared wearing undergarments in cotton. Regarding the daily vaginal douching behaviors, the majority (76.3%; n=61/80) of participants used the recommended gynecological measure, while the remaining use self-prescribed measures. Both genital parts (vulva area and vagina) were cleaned and use of water was mostly cited (63.8%; n=51/80). Almost one participant on four (n=29/80) use antiseptic solutions for genital cleaning. Antiseptic solutions were associated with water in 34.5% of cases (n=10/29), and in 65.5% (n=19/29) of cases it was used only for the vagina. Our findings suggest that knowledge and genital hygiene cleaning practices are acceptable among our study population. Risky practices such as use of antiseptic solutions and synthetic underwear's were reported. Skills of health care providers on good hygiene practices for pregnant should be improved and community-based communication strategies need to be implemented to reach all women of child bearing age.
