Seminal plasma plus sperm

Effect of seminal plasma and sperm of boars valued by freezability on seminal cryopreservation. Abstract: The aim of this study was to determine the effect of sperm and seminal plasma SP on the freezability of porcine semen. Semen of eight commercial males from two farms in the central-western region of Colombia four boars in each farm was frozen and tested to select two males with high freezability MHF and two with low freezability MLF , according to the percentage of functionally competent sperm FCS. Immediately after the collection was completed, the SP and sperm from the males selected were separated by centrifugation to combine the two types of plasma with the two types of sperm, incubate them for three hours and then freeze them.

Try out PMC Labs and tell us what you think. Learn More. For human infertility both male and female factors may be equally important. Searching for molecular biomarkers of male infertility, neglected for decades, and the attempts to explain regulatory mechanisms of fertilization become thus extremely important. Apart from examination of the structure and function of male gametes, also the possible importance of seminal plasma components should be considered.

Understanding the seminal plasma proteome and its role in male fertility

Basic and Clinical Andrology volume 28 , Article number: 6 Cite this article. Metrics details. While it has been established that seminal plasma serves not only as a medium to carry, protect, and nourish sperm after ejaculation up to fertilization, but also as a functional modulator of sperm function, there is still a need to properly characterize the molecular make-up of seminal plasma in fertile men, and to understand how this is altered in different causes of male infertility. The main purpose of this manuscript was to review articles that studied the human seminal plasma proteome, ranging from characterizing a fertile seminal plasma proteomic map to studies comparing seminal plasma from fertile and infertile men, and comparing seminal plasma of fertile or normozoospermic men to a diverse range of biological causes for male infertility.

Ejaculation results in the confluence of epididymal spermatozoa with secretions of the accessory sex glands. This interaction is not a prerequisite for fertilisation success, but seminal factors do play a crucial role in prolonging the survival of spermatozoa both in vitro and in vivo by affording protection from handling induced stress and some selective mechanisms of the female reproductive tract. Reproductive biologists have long sought to identify specific factors in seminal plasma that influence sperm function and fertility in these contexts.
