Sperm banking can preserve male fertility effectively, but the current conditions of sperm cryopreservation in China have not been investigated. This retrospective investigation was based on data collected at multiple centres in China from January 2003 to December 2008. The collected data included urogenital history, indication for cryopreservation, semen parameters, use rate, type of assisted ...

AIMS In this study we report our results with storage of cryopreserved semen intended for preservation and subsequent infertility treatment in men with testicular cancer during the last 18 years. METHODS Cryopreserved semen of 523 men with testicular cancer was collected between October 1995 and the end of December 2012. Semen of 34 men (6.5%) was used for fertilization of their partners. The...

The aim of the present study was to evaluate the quality of raw and cooled semen in Icelandic stallions. Experiments were performed using seven stallions aged between 3 and 19 years. From each stallion, six ejaculates were collected, and semen quality was determined. Thereafter, the semen was split into eight equal parts and processed with and without centrifugation using the extenders INRA 82-...

The objective of this experiment was to evaluate spermatological parameters and fertilizing ability of short term stored semen in different extenders from endemic Abant trout (Salmo trutta abanticus T,1954). Semen was collected from 30 adult males by the hand stripping method without anesthesia. Having determined the main spermatological properties (volume, motility, movement duration, concentr...

Semen quality assessment methods are very important in predicting the fertilizing ability of persevered spermatozoa and to improve animal reproductive technology. This review discusses some of the current laboratory methods used for semen quality assessments, with references to their relevance in the evaluation of male fertility and semen preservation technologies. Semen quality assessment meth...

The aim of the study was to evaluate the effect of semen storage on ferrous ion induced luminescence of boar spermatozoa and to determine the relationship between parameters of this luminescence and lipid peroxidation as measured by malondialdehyde (MDA) contents. Boar semen samples were diluted in Biosolwens extender and stored for 12 days at 15 degrees C. Luminescence and MDA were measured di...

PURPOSE Whether the presence or specific type of cancer significantly affects semen quality is controversial. We evaluated the semen parameters and associated malignancies of men with cancer who cryopreserved sperm at our institution before undergoing therapy. MATERIALS AND METHODS We reviewed the database from our cryopreservation laboratory during a 5-year period. Office charts of 409 of 1,...

Background: Hen egg yolk is a common component of most semen cryopreservation extenders. However, diluents containing the egg yolk may have adverse effects on the quality of the semen. Egg yolk could be solubilized by the addition of sodium dodecyl sulphate (SDS) in semen extenders. Many studies have shown beneficial effects of antioxidants addition to semen freezing extenders. Antioxidants are...

Background and Purpose: Antioxidant reduces oxidative stress during cryo-preservation. The aim of this study was to find out the effects of vitamin E and C on sperm parameters after cryo-preservation. Materials and Methods: Human semen samples were obtained from Vali-e-asr Hospital. The samples were divided in two groups (normal and oligospermia groups). Semen was pooled in liquid nitrogen...
