This experiment was designed to study the effect of insulin like growth factor-I (IGF-I) on cryopreservation of Hariana bull semen. For this purpose, semen ejaculates were collected from four Hariana bulls using artificial vagina at biweekly interval. The semen samples which possess more than 70% initial progressive motility and above 500 million/mL spermatozoa concentration was subsequently su...

OBJECTIVE To explore the possibility of using the L4 membrane filtration device for processing of spermatozoa for intrauterine insemination and other assisted reproductive techniques. DESIGN, SETTING, PATIENTS Semen samples from 15 patients attending an infertility clinic of a tertiary referral institution and from seven fertile donors were used for the study. MAIN OUTCOME MEASURES The effe...

The examination of quality of the sperm ejaculate is one of the most important steps in artificial fertilization procedure. The main aim of semen storage centres is to characterise the best semen quality for fertilization. Reliable information about sperm motility is also one the most important parameters for in vitro laboratory procedures. There exist very expensive automated methods for semen...

Semen cassiae is the ripe seed of Cassia obtusifolia L. or Cassia tora L. of the family Leguminosae. In traditional Chinese medicine, the two forms of Semen cassiae are raw Semen cassiae (R-SC) and parched Semen cassiae (P-SC). To clarify the processing mechanism of Semen cassiae, the pharmacokinetics of R-SC and P-SC extracts were examined. A simple, rapid, sensitive ultra-high-performance liq...

It is known that livestock animal semen very sensitive to cold shock during freezing processes, and this sensitivity directly affects post-thaw progressive motility, mitochondrial membrane potential, sperm nuclear DNA integrity in vitro spermatological parameters such as plasma acrosome integrity, fertility. In addition, with the sudden decrease total antioxidant level of after thawing, cells a...

background: no extensive studies were done that included the use of pentoxifylline or verify its effect on the outcome of icsi in cases of mild and moderate asthenozoospermia. objective: the aim of this study was to evaluate the effect of pentoxifylline used in preparation of semen samples which doesn't need motility enhancement prior to icsi. materials and methods: the study was carried on 30 ...

Background: Sperm preparation is a fundamental step in ART and attempt for developing new methods to be continued. Objective: To evaluate the efficacy of upstream method for separation of human spermatozoa and its effects on sperm parameters including: motility, morphology, and concentration. Materials and Methods: Semen samples from 17 men who referred to infertility clinic for evaluating thei...

Semen Cuscutae is a well-known Chinese medicine which has been used to nourish kidney in China for thousands of years. The crude product of semen Cuscutae (CP) and its salt-processed product (SPP) are separately used in clinic for their different effects. The study was designed to investigate the influence of processing from semen Cuscutae on chemical components and biological effects. The prin...

Objective: Using correlation analysis between the sperm spontaneous acrosome reaction rate (SARR) and routine semen parameters in male infertility patients, we explored the value of the sperm spontaneous acrosome reaction in the evaluation of sperm functions. Methods: The participants comprised of 219 male infertility patients who had visited the Center for Reproductive Medicine, Shandong Unive...
