Animal genitalia often show distinct developmental and evolutionary relationships with other parts of the body. Morphological observations of 29 sexually dimorphic and monomorphic beetle species in 16 genera of families Scarabaeidae and Lucanidae, Coleoptera, in 53 locations revealed that male genitalia size was consistently and distinctly less variable than that of other body parts within the ...

Studies of hybridization have increased our understanding of the nature of species boundaries, the process of speciation, and the effects of hybridization on the evolution of populations and species. In the present study we use genetic and morphological data to determine the outcome and consequences of secondary contact and hybridization between the butterfly species Lycaeides idas and L. melis...

• More than 71,000 women in the United States were diagnosed with a cancer affecting the reproductive organs. • More than 27,000 women in the United States died from some form of gynecologic cancer. • Uterine (endometrial) cancer is the most common gynecologic cancer. • Ovarian cancer is the most deadly gynecologic cancer. • Cervical cancer was once the leading cause of death for women in the U...

Caesalpinia ferrea Mart (Leguminosae) is a medicinal plant used to treat diabetes, among other therapeutic properties, but which is also reported to have hepatotoxic effects. Although it contains substances such as flavonoids and coumarin, which are known to have antifertility activity, no studies have apparently been conducted to evaluate the potential adverse side effects of this plant on the...

Prevalence of abortion is higher in women with autoimmune thyroid disease. In the majority of cases, however, no abnormality of thyroid function is detected despite the high levels of antithyroid antibodies. The direct influence of such harmful autoantibodies in female reproductive organs may serve a role in pregnancy loss. In this study, expression of thyroglobulin in the reproductive tissues ...

Bacteria, parasites, viruses and fungi are some important clinical pathogens that may cause the microbial infections of male reproductive tracts, and also interfere with the reproductive function in male [2]. 15% of the cases of male infertility are due to reproductive tract inflammations and infections [3]. Several organs of the male reproductive system, such as male accessory sex glands, test...

BACKGROUND Adenosquamous carcinoma (ASC) is a rare disease involving various organs, yet there are no large-scale population-based comparative studies on ASC among different organs. METHODS The incidence and overall survival of ASC among various organs in cases diagnosed in Taiwan from January 1, 2003 to December 31, 2010 were calculated and compared using data from the Taiwan Cancer Registry...

Although there has been an upsurge of interest in research on women’s sexual and reproductive health, most of the research has remained confined to the obstetrics and gynecology disciplines, without knowledge flow to the biomechanics community. Thus, the mechanics of the female reproductive system and the changes determined by pregnancy, age, obesity, and various medical conditions have not bee...
