Theory predicts that costly secondary sexual traits will evolve heightened condition dependence, and many studies have reported strong condition dependence of signal and weapon traits in a variety of species. However, although genital structures often play key roles in intersexual interactions and appear to be subject to sexual or sexually antagonistic selection, few studies have examined the c...

The male uro-genital tract is susceptible to gram-negative bacterial infections that produce a state of inflammation, particularly in the testis and epididymis. Development of germline stem cells into motile spermatozoa takes place in these organs and thus any impairment therein has a direct effect on male fertility. A number of factors are known to impair male fertility including environmental...

Background and aim: Pemphigus vulgaris (PV) is an autoimmune blistering disease which is known to involve the female genital tract but the frequency at which this occurs is unknown. There are relatively few reports in the literature of the cytological appearance of PV on cervicovaginal smears. Our aim was to evaluate involvement of the female genital tract and cervicovaginal Papanicolaou ...

Of 1,486,984 new cancers registered in the Czech Cancer Registry in 1976-2005, 290,312 (19.5%) were multiple malignant neoplasms (MMNs), of which there were 65,292 primary and 89,796 subsequent cases in men and 59,970 primary and 75,254 subsequent cases in women. The duplicities were higher in women, and the triplicities and others (3-6 MMNs) were higher in men. The most frequent diagnoses were...

Mycoplasma pneumoniae is a common etiologic agent of lower respiratory tract infections in humans. However, it has been reported previously that the organism has occasionally been isolated from sites other than the oropharynx and respiratory tract. We report the isolation of 24 strains of M. pneumoniae from urogenital specimens obtained from 22 female patients. Most isolates were of cervical or...

Background: There is controversy over the role of asymptomatic genital tract infection of Chlamydia trachomatis (C. trachomatis) in the etiology of male infertility. Aim of the Study: Detection of chlamydia antibodies in seminal plasma of infertile men and its effect on semen parameters. patients and Methods : Semen samples were collected from 144 infertile male, 35 normal fertile male ,seminal...

BACKGROUND Compartmentalization of HIV-1 between the genital tract and blood was noted in half of 57 women included in 12 studies primarily using cell-free virus. To further understand differences between genital tract and blood viruses of women with chronic HIV-1 infection cell-free and cell-associated virus populations were sequenced from these tissues, reasoning that integrated viral DNA inc...

A wide variety of organisms from the environment invade the preputial cavity of rams. Various of these organisms can be isolated from the deeper parts of the male genital tract, and especially from the accessory glands. Some of the bacteria present in the sheath can be stimulated to migrate to the deeper parts of the genital tract by injections into the host animal of luteinizing-hormone-releas...

We tested the hypothesis that the intensity of specific antichlamydial T cell-mediated immunity in the genital tract of female guinea pigs infected intravaginally with the chlamydial agent of guinea pig inclusion conjunctivitis would determine the resistance or susceptibility to reinfection after a primary chlamydial infection. T cell-enriched lymphocytes were isolated by collagenase treatment ...
