The connection between human papillomavirus (HPV) infection and the consequent sequelae which establishes cervical neoplastic transformation and invasive cervical cancer has redefined many aspects of cervical cancer research. However there is still much that we do not know. In particular, the impact of external factors, like seminal fluid in sexually active women, on pathways that regulate cerv...

Seminal fluid proteins (SFPs) produced in reproductive tract tissues of male insects and transferred to females during mating induce numerous physiological and behavioral postmating changes in females. These changes include decreasing receptivity to remating; affecting sperm storage parameters; increasing egg production; and modulating sperm competition, feeding behaviors, and mating plug forma...

The present report was designed to study the macrophage role and their association with percentage of spermatozoa showing DNA native, morphologically normal sperm and occurrence of antibody-coated spermatozoa. Human sperm samples from 31 patients were used in this study. All samples were evaluated for standard semen parameters according to World Health Organization criteria. The sperm heads wit...

The events that generate T cell-mediated immune tolerance in early pregnancy are ill-defined. To investigate the significance of seminal fluid Ags in activating maternal T cells, and define the underlying Ag presentation pathways, OVA-specific T cells were adoptively transferred to female mice inseminated by males ubiquitously expressing membrane-bound OVA. OVA-reactive CD8(+) OT-I and CD4(+) O...

Background and Objectives According to Islamic doctrines, the use of gold for men has been banned. In general, any advised subject in Islam is useful for the body and what has definitely forbidden for a man is definitely harmful for him although its reasons have not been exactly specified. However, Muslims believe that there is certainly a sound reason behind this prohibition. This issue was st...

609 Abstract: In order to determine the seminal activity of LDH-C4 and to investigate its correlation with other fertility indexes, we studed total LDH, total CK avtivities, and LDH-C4 in relation to sperm count, motility and sperm motility index (SMI). SMI is the measurement of electro-optical fluctuations caused by motile sperm. Total LDH and total CK were determined with a Technicon RA 1000 ...

Seminal fluid proteins have been shown to play important roles in male reproductive success, but the mechanisms for this regulation remain largely unknown. In Caenorhabditis elegans, sperm differentiate from immature spermatids into mature, motile spermatozoa during a process termed sperm activation. For C. elegans males, sperm activation occurs during insemination of the hermaphrodite and is t...

Male reproductive fitness is strongly affected by seminal fluid. In addition to interacting with the female environment, seminal fluid mediates important physiological characteristics of sperm, including capacitation and motility. In mammals, the male reproductive tract shows a striking degree of compartmentalization, with at least six distinct tissue types contributing material that is combine...
