casa (computer assisted semen analysis) systems are designed to assist andrologist labour. most available casa systems are not accurate or so expensive. therefore labours use manual methods to provide parameters. although some companies have achieved appropriate accuracy, they have not released their methods. so proposing methods in this area might be useful for groups who intend to design new ...

BACKGROUND Sperm selection method is usually used to collect these cells for in vitro-assisted reproduction. Few studies reported the relationship of in vivo fertility and semen parameters after sperm selection; hence, the present study attempted to assess different semen parameters after post-thaw or sperm selection, using density gradient separation BoviPure®, to predict in vivo fertility. ...

The mucosal events of HIV transmission have been extensively studied, but the role of infected cells present in the genital and rectal secretions, and in the semen, in particular, remains a matter of debate. As a prerequisite to a thorough in vivo investigation of the early transmission events through infected cells, we characterized in detail by multi-parameter flow cytometry the changes in ma...

background: the aim of the study was to assess the effect of four repeated ejaculations on the same day at two-hour intervals on conventional and functional semen parameters. methods: three healthy men (32±3.6 years) donated the first semen samples after 3-4 days of sexual abstinence followed by three subsequent samples on the same day at two-hour interval each. semen samples were processed and...

A practical approach to semen analysis (SA) interpretation and the initial management of subfertile men is presented. Each parameter of the SA is described and management recommendations based upon SA findings are provided. The indications for and interpretation of adjunctive diagnostic testing for male factor subfertility are also discussed.

Background: Artificial insemination (AI) has been used for increasing genetic potential of animals in production while application of AI has been restricted in buffalo due to low freezing ability and fertility of frozen-thawed buffalo spermatozoa. So improvement in buffalo sperm cryopreservation may enhance the breeding programs of this valuable farm animal. Semen processing is one of the major...

Fertility rates have dramatically decreased in the last two decades, especially in men. It has been described that environmental factors as well as life habits may affect semen quality. In this paper we use artificial intelligence techniques in order to predict semen characteristics from environmental factors, life habits and health status, as a possible Decision Support System that can help in...

OBJECTIVE The goal of this study was to compare the semen parameters of two successive samples obtained within an interval of less than 60 minutes from patients planning to undergo intrauterine insemination (IUI) whose first samples exhibited low semen quality. METHODS Thirty-two consecutive patients were enrolled in the study. On the day of IUI, the semen analysis of the samples initially pr...
