this study was carried out to compare the histomorphological structures of oviductal regionsof the apparently healthy adult laying hens (gallus gallus dometicus) and ducks (ansa ansadomesticus). for this purpose, 20 hens and 20 female ducks aged between 1–1.5 years were used.after euthanasia, the oviducts were dissected out and all of the gross morphometrical parametersincluding length, width a...

Three cases of ceroid granulomas of the female genital system are presented, involving the cervix in two and lesions in the ovaries and bowel serosa in the other. Ceroid granulomas are unusual and interesting lesions formed when suitable substrates accumulate within macrophages to such an extent that a relative lack of biological antioxidants results and auto-oxidation and conversion to ceroid ...

Despite the key functions of the genitalia in sexual interactions and fertilization, the role of sexual selection and conflict in shaping genital traits remains poorly understood. Seed beetle (Callosobruchus maculatus) males possess spines on the intromittent organ, and females possess a thickened reproductive tract wall that also bears spines. We investigated the role of sexual selection and c...

OBJECTIVE To describe a new system for classifying genital ambiguity and urogenital sinus abnormalities. Prader's classification (which attempts to describe the degree of masculinization) has been used for decades, while the urogenital sinus has generally been described as simply high or low; neither classification fits the spectrum of anomalies, nor do they allow for outcome data research. M...

To date, it has not been possible to study antigen-specific T cell responses during primary infection of the genital tract. The low frequency of pathogen-specific T cells in a naïve mouse makes it difficult to monitor the initial events after antigen encounter. We developed a system to examine the response of pathogen-specific T cells in the genital mucosa after intrauterine infection. We ident...

The incidence of congenital malformation of the urogenital system is second only to that of the cardiovascular system, yet comparatively little is known about the cellular and molecular mechanisms that regulate urogenital organogenesis. In this chapter, I review recent advances in the developmental biology of the external genitalia, and discuss the implications of this work for our understandin...

BACKGROUND The objective of this study is to estimate the incidence of genital warts in Hong Kong and explore a way to establish a surveillance system for genital warts among the Hong Kong general population. METHODS A total of 170 private doctors and all doctors working in the 5 local Social Hygiene Clinics (SHC) participated in this study. During the 14-day data collection period (January 5...
