Normal sexual differentiation in the genital organs is essential for the animal species that use sexual reproduction. Although it is known that doublesex (dsx) is required for the sexual development of the genitalia in various insect species, the direct target genes responsible for the sexual differentiation of the genitalia have not been identified. The lozenge (lz) gene is expressed in the female genital disc and is essential for developments of spermathecae and accessory glands in Drosophila melanogaster...

Elevated inflammation in the female genital tract is associated with increased HIV risk. Cervicovaginal bacteria modulate genital inflammation; however, their role in HIV susceptibility has not been elucidated. In a prospective cohort of young, healthy South African women, we found that individuals with diverse genital bacterial communities dominated by anaerobes other than Gardnerella were at over 4-fold higher risk of acquiring HIV and had increased numbers of activated mucosal CD4(+) T cells compared to those with Lactobacillus crispatus-dominant communities...

BACKGROUND: Chlamydia, caused by the bacterium Chlamydia trachomatis(C. trachomatis), is the most common sexually transmitted disease. The incidence is not clear due to the asymptomatic nature of early stage of infections. The incidence of Chlamydia has not been fully investigated in the Chinese Han population. Since chronic infection with can C. trachomatis can lead to infertility in males and females, it is important to determine the impact of infection on clinical outcomes. The aim of this study is to explore the epidemiology of C...

BACKGROUND: Evidence on clitoral reconstruction after female genital mutilation is lacking. CASE: A woman with female genital mutilation experiencing clitoral pain during sex consulted to undergo clitoral reconstruction. The surgery was complicated by a wound infection responsible for severe postoperative pain. Such genital pain made our patient recall the traumatic experience of genital mutilation and experience a relapse of posttraumatic stress disorder symptoms...

BACKGROUND: To determine if female partners of men with pathogen-negative non-gonococcal urethritis (NGU) are at risk of genital infection. METHODS: Secondary data analysis using health records from a large sexually transmitted disease clinic in Melbourne of 1710 men and their female partners attending on the same day from January 2006 to April 2015. Proportions of female partners with symptoms suggesting genital infection or pelvic inflammatory disease (PID) were determined for: (1) men with NGU and no Chlamydia trachomatis or Mycoplasma genitalium (referred to as pathogen-negative NGU) (n = 91); 2) men with urethral C...

Category-specific sexual response describes a pattern wherein the individual shows significantly greater responses to preferred versus nonpreferred categories of sexual stimuli; this pattern is described as gender specific for sexual orientation to gender, or gender nonspecific if lacking response differentiation by gender cues. Research on the gender specificity of women's sexual response has consistently produced sexual orientation effects, such that androphilic women (sexually attracted to adult males) typically show gender-nonspecific patterns of genital response and gynephilic women (sexually attracted to adult females) show more gender-specific responses...

Chronic GvHD (cGvHD) of the genital tract is an underreported and infrequently recognized complication of allogeneic hematopoietic cell transplantation in both male and female long-term survivors. Its pathophysiology, clinical manifestations and management are not well understood, and studies are limited. We thus provide a comprehensive review of genital cGvHD in both men and women, as well as discuss related issues of sexual health and viral reactivation. We further provide guidance on screening, management and long-term follow-up, as well as future priority areas of study...

Given the potential significance of mutilation of the external genitalia in medicolegal fatalities, a review of the literature was undertaken to identify subcategories. Such mutilations may have been sustained sometime before death, around the time of death, or after death. The most common type of ante mortem genital mutilations involves cultural practices such as male circumcision. Less common male mutilations such as subincisions are tribally based. Female genital mutilation is found particularly in African, Middle Eastern, or Asian populations...

Fertilization is exceptionally complex and, depending on the species, happens in entirely different environments. External fertilizers in aquatic habitats, like marine invertebrates or fish, release their gametes into the seawater or freshwater, whereas sperm from most internal fertilizers like mammals cross the female genital tract to make their way to the egg. Various chemical and physical cues guide sperm to the egg. Quite generally, these cues enable signaling pathways that ultimately evoke a cellular Ca(2+) response that modulates the waveform of the flagellar beat and, hence, the swimming path...

Worldwide most HIV infections occur through heterosexual transmission, involving complex interactions of cell-free and cell-associated particles with cells of the female genital tract mucosa. The ability of HIV-1 to "infect" epithelial cells remains poorly understood. To address this question, replicative-competent chimeric constructs expressing fluorescent proteins and harboring the envelope of X4- or R5-tropic HIV-1 strains were used to "infect" endometrial HEC1-A cells. The virus-cell interactions were visualized using confocal microscopy (CM) at various times post infection...

A method for observing and quantifying the mating behavior of the pinewood nematode, Bursaphelenchus xylophilus, was established under a stereomicroscope. To improve the mating efficiency of B. Xylophilus and to increase the chances of mating observation, virgin adults were cultured and used for the investigation. Eggs were obtained by keeping the nematodes in water and allowing the females to lay eggs for 10 min. The second-stage juveniles (J2) were synchronized by incubating the eggs for 24 h at 25 °C in the dark, and the early J4 were obtained by culturing the J2 with grey mold, Botrytis cinerea, for another 52 h...

Müllerian anomalies are defined as congenital uterine malformations that arise from improperly developing Müllerian ducts. These malformations have a variety of presentations ranging from asymptomatic to amenorrhea, dyspareunia, dysmenorrhea, chronic pelvic pain, pregnancy loss, fetal malpresentation, placental abruption, and intrauterine growth restriction. In this review, we discuss the clinical implications, diagnosis, and treatment of the various Müllerian anomalies focusing on the ones for which clinical intervention is amenable to improve pregnancy outcomes...

Investigations of sexual concordance suggest that, on average, women exhibit a low, positive correlation between their subjective sexual arousal and genital response. However, this relationship appears to be stronger, on average, when genital response is measured via the external tissues of the vulva than within the vagina walls. Given the methodological variations, such as stimulus content and duration, in studies of vulvar and vaginal concordance, direct comparisons between individual studies are limited...

Adenomatoid tumors are neoplasms of mesothelial origin, usually occurring in the male and female genital tracts. Extragenital localization sites such as adrenal glands are rare but have been reported. When found in the adrenals, they represent great clinical, radiological and pathological diagnostic challenge, with wide range of differential diagnoses to be considered. We present a case of a 30 years old female, with incidental ultrasound finding of unilateral tumor in the right adrenal gland. Multi slices CT scan was of value in localizing this tumor, but not in the precise diagnosis...

Neuroendocrine tumors (NETs) are aggressive diseases developing from neuroendocrine cells that most frequently involve the gastro-entero-pancreatic tract and the lung, but more rarely are found in almost all body tissues. Limited biological and clinical data are currently available for NETs in uncommon sites, such as female genital tract. NETs represent 0.9% to 1.5% of the tumors of the uterine cervix. They are more likely to have lymph-vascular space invasion and lymph node involvement, and to develop local and distant relapses when compared with the mostly common cervical squamous cell carcinomas or adenocarcinomas...
