Vaginal delivery is commonly accepted as a risk factor in pelvic floor dysfunction (PFD), however, other obstetric procedures (episiotomy) are still controversial. In this work, to analyze the relationship between episiotomy and pelvic floor function, a finite element model (FEM) of the pelvic cavity is used considering the pelvic floor muscles (PFM) with damaged regions from spontaneous vaginal delivery, and from deliveries with episiotomy. Common features assessed at screening of PFD are evaluated during numerical simulations of both Valsalva maneuver and contraction...

CONTEXT: A "Transgender" person is one who dresses as, desires to be, has undergone surgery to become or identifies with opposite sex. They have a higher risk of sexually transmitted infection (STI) due to a combination of biological and social reasons. They have risky sexual behaviors but low-risk perception. AIMS: The aim of this study is to determine the prevalence of STI/human immunodeficiency virus (HIV) in transgender (TG) and association with condom use. SETTINGS AND DESIGN: A retrospective study of 82 male-to-female TGs attending our sexually transmitted disease (STD) clinic from 2011 to 2014 was undertaken...

Human infection by HIV is spreading rapidly. The spread of the virus is generally organized and transmission can be rectal, oral, or penile. Several types of cells are susceptible to viral invasion. The appearance of symptoms during infection can vary, but the presence of the virus can be confirmed by testing for the antigen p24. The ELISA test is used to detect viral p24 antigen and antiviral antibodies. This technique is approved for the purposes of clinical practice. Highly active antiretroviral therapy is usually a costly and lengthy treatment for HIV infection...

In the last decades, selection for improved prolificacy has resulted in higher litter sizes and has thereby increased the proportion of low birthweight (LW) piglets. It is well documented that LW piglets have lower growth performance, muscle accretion and poor carcass quality. However, little is known about the relations of birthweight with subsequent reproductive performance in gilts. This study investigated the effects of birthweight on reproductive tract and ovarian follicle development in 150-day-old gilts...

Tumours and tumour-like lesions are rare findings in the genital system of guinea pigs. The aim of the present study was to characterize nodular lesions in the cervix and uterus of guinea pigs submitted for histopathological diagnosis. Samples from 83 pet animals were investigated. Cases included 64 surgically excised masses including complete uteri (n = 37), parts from uteri containing masses (n = 8), complete masses (n = 12) or samples from masses (n = 7) and 19 complete necropsy examinations. In 55 of the cases, only solitary changes were observed; in 28 cases two or more lesions were diagnosed...

BACKGROUND: Access to highly specialized health care services and support to meet the patient's specific needs is critical for health outcome, especially during age-related transitions within the health care system such as with adolescents entering adult medicine. Being affected by an orphan disease complicates the situation in several important respects. Long distances to dedicated institutions and scarcity of knowledge, even among medical doctors, may present major obstacles for proper access to health care services and health chances...

Gammaherpesviruses are important human and animal pathogens. Infection control has proved difficult because the key process of transmission is ill-understood. Murid herpesvirus-4 (MuHV-4), a gammaherpesvirus of mice, transmits sexually. We show that this depends on the major virion envelope glycoprotein, gp150. Gp150 is redundant for host entry and, in vitro, it regulates rather than promotes cell binding. We show that gp150-deficient MuHV-4 reaches and replicates normally in the female genital tract after nasal infection, but is poorly released from vaginal epithelial cells and fails to pass from the female to the male genital tract during sexual contact...

Using mixed methods that combined participant observation and semi-structured in-depth interviews, this study looked at changing practices and shifting meanings of female genital cutting among the Maasai people in Tanzania. The findings suggest that an increasing social pressure to abandon female genital cutting has inspired the hiding of the practice, causing the actual cutting to become detached from its traditional ceremonial connotations. This detaching of cutting from ceremony has created a shift in meanings: the ceremony still carries the meaning of passage into adulthood, while the cutting seems to function as a way of inscribing Maasai identity into the body...

High-risk human papillomavirus (HPV) infection is the etiological agent of some malignancies such as cervical, oral and oropharyngeal cancers. Kaposi sarcoma-associated herpesvirus (KSHV) represents a principal causative agent of several human cancers arising in those immunocompromised patients. Interestingly, KSHV DNA has been detected in the oral cavity and the female genital tract, although its detection rate in cervical samples is very low and few reports are about KSHV/HPV co-infection. Therefore, it remains unclear about the role of KSHV co-infection in the development of HPV-related neoplasias...

Chlamydia trachomatis serovars D-K are one of the most frequent causes of sexually transmitted infections of the female genital tract, with possible complications such as hydrosalpinx, pelvic inflammatory disease, extra-uterine gravidity or infertility. We used the murine genital tract infection model with C. muridarum for vaccination studies and found that more than 70% of the infected mice suffered from uterus dilatations and/or hydrosalpinx. Systemic consequences of the vaginal infection were apparent by splenomegaly ten to fifteen days post infection...

Within the cell, gene expression analysis is the key to gain information about  different cellular and physiological events. The multifaceted route of fertilization is a combination of different processes, which include production, maturation and ejaculation of the sperm, its travel through the female genital tract, followed by the ultimate fusion of the fertile sperm with the egg. Early embryogenesis and gametogenesis as well as gene expression at tissue level and global gene silencing are under different levels of stringent epigenetic checks...

Recent progress in germ cell transplantation techniques in fish has paved the way for the conservation of endangered species. Here, we developed an intraperitoneal germ cell transplantation procedure using Chinese and Dabry's sturgeon as donor and recipient species, respectively. Histological analysis revealed that primordial germ cells migrated on the peritoneal wall at 16 days post-hatch (dph) in Dabry's sturgeon. The genital ridges of Dabry's sturgeon (recipient) first formed at 28 dph, suggesting that for successful colonization of donor germ cells in the recipient gonads, the transplantation should be performed earlier than this age...

HIV vaginal transmission accounts for the majority of newly acquired heterosexual infections. However, the mechanism by which HIV spreads from the initial site of viral entry at the mucosal surface of the female genital tract to establish a systemic infection of lymphoid and peripheral tissues is not known. Once the virus exits the mucosa it rapidly spreads to all tissues, leading to CD4(+) T cell depletion and the establishment of a viral reservoir that cannot be eliminated with current treatments. Understanding the molecular and cellular requirements for viral dissemination from the genital tract is therefore of great importance, as it could reveal new strategies to lengthen the window of opportunity to target the virus at its entry site in the mucosa where it is the most vulnerable and thus prevent systemic infection...

Aside from phosphodiesterase (PDE) isoenzymes, protein kinases (cAK=cyclic AMP-binding protein kinase, cGK=cyclic GMP-binding protein kinase) have also been identified as important receptors for cyclic nucleotides. A significance of protein kinases in the control of the function of the male and female reproductive tract has been suggested; however, up until today, only a few approaches have addressed these enzymes in female genital tissues. The present study aimed to investigate by means of biochemical and immunohistochemical methods the expression of cAK and cGK...

Background: Studies have demonstrated the role of ulcerative and non-ulcerative sexually transmitted infections (STI) in HIV transmission/acquisition risk; less is understood about the role of non-specific inflammatory genital abnormalities. Methods: HIV-discordant heterosexual Zambian couples were enrolled into longitudinal follow-up (1994-2012). Multivariable models estimated the effect of genital ulcers and inflammation in both partners on time-to-HIV transmission within the couple...

Streptococcus pyogenes (GAS) is one of the major human pathogenic bacteria that cause a wide range of diseases. Currently, increased incidence of streptococcal invasive infections is observed worldwide. In this study, we focused on the prevalence of genes encoding superantigens and type M proteins in the population of GAS strains from invasive versus non-invasive infections. We tested 253 GAS strains: 48 strains from patients with invasive infections (18 from wound/deep skin localization, 30 from women in labour) and 205 strains from non-invasive forms (147 from common infections of the upper respiratory, 49 from the vagina of females with genital tract infections and 9 from non-invasive wound and superficial skin infections)...

The MtrCDE efflux pump of Neisseria gonorrhoeae contributes to gonococcal resistance to a number of antibiotics used previously or currently in treatment of gonorrhea, as well as to host-derived antimicrobials that participate in innate defense. Overexpression of the MtrCDE efflux pump increases gonococcal survival and fitness during experimental lower genital tract infection of female mice. Transcription of mtrCDE can be repressed by the DNA-binding protein MtrR, which also acts as a global regulator of genes involved in important metabolic, physiologic, or regulatory processes...
