Prolactin-induced Modulation of Tissue Growth Rate Patterns in Albino Rats During Puberal Transition
prolactin growth rate curves tissue somatic indices advancement of puberty accessory male reproductive glands
2009/2/19
The role of prolactin (PRL) in the puberal transition of male albino rats has been investigated. It was found that PRL elevated total organ growth rates, tissue somatic indices, and dry weights of r...
Prostatic growth rate determined from MRI data：age-related longitudinal changes
Prostatic growth rate MRI data age-related longitudinal changes
2009/2/18
Men with prostatic enlargement are at highest risk of developing symptomatic lower urinary tract symptoms (LUTS) and related outcomes, such as acute urinary retention. The study of prostatic growt...
Correlation between the rate of lipid peroxidation and cellular maturity as measured by creatine kinase activity in human spermatozoa
Spermatogenesis sperm development oligospermia male fertility
2009/2/12
We have demonstrated previously that creatine kinase (CK) activity is a measure of cellular maturity and fertilizing potential in human spermatozoa. In the present work we have examined whether th...
The Analysis of Meiotic Segregation Patterns and Aneuploidy in the Spermatozoa of Father and Son With Translocation t（4;5）（p15.1;p12）and the Prediction of the Individual Probability Rate for Unbalanced Progeny at Birth
FISH risk assessment
2008/12/24
Reciprocal chromosomal translocations (RCT) have long been recognized as important etiological factors in reproductive failure. In the present study, the meiotic segregation patterns of the sperm...
Increased Aneuploidy Rate in Sperm With Fragmented DNA as Determined by the Sperm Chromatin Dispersion（SCD）Test and FISH Analysis
Human fragmentation
2008/12/24
Previous studies suggest that sperm DNA fragmentation may be associated with aneuploidy. However, currently available tests have not made it possible to simultaneously perform DNA fragmentatio...
Could Sperm Aneuploidy Rate Determination Be Used as a Predictive Test Before Intracytoplasmic Sperm Injection?
Chromosomal profile fluorescent in situ hybridization spermatozoa
2008/12/23
Chromosome abnormalities in embryos are a major cause of implantation and development failures. Some couples with normal karyotypes have repeated implantation failures after intracytoplasmic sperm...
Relationship Between Sperm Viability as Determined by Flow Cytometry and Nonreturn Rate of Dairy Bulls
Spermatozoa quality insemination fertility precision accuracy
2008/12/23
A newly developed flow cytometric method for determination of sperm concentration and viability was tested in an insemination trial with cryopreserved bull sperm to establish the relationship betwee...
Primary Flagellar Abnormality Is Associated With an Increased Rate of Spermatozoa Aneuploidy
Chromosome abnormalities FISH flagellum male infertility sperm
2008/12/22
The frequencies of aneuploid and diploid spermatozoa were determined in 3 patients presenting a complete asthenozoospermia due to a primary and specific flagellar anomaly: patients 1 and 2 presented...
Selection of Individual Testicular Tubules From Biopsied Testicular Tissue With a Stereomicroscope Improves Sperm Retrieval Rate
intracytoplasmic sperm injection testicular sperm extraction microdissection spermatozoa nonobstructive azoospermia
2008/12/22
The present study describes a new modification for testicular sperm extraction (TESE) with an intraoperative surgical loop, coupled with stereomicroscopic dissection in the laboratory, to identify...
Absolute Polymorphic Teratozoospermia in Patients With Oligo-Asthenozoospermia Is Associated With an Elevated Sperm Aneuploidy Rate
Enlarged sperm head fluorescence in situ hybridization male infertility
2008/12/19
Infertile patients with abnormal sperm parameters have an increased sperm aneuploidy rate, despite a normal blood karyotype. The evaluation of sperm chromosome aberrations in patients with teratozoo...
Usefulness of the Hypo-Osmotic Swelling Test in Predicting Pregnancy Rate and Outcome in Couples Undergoing Intrauterine Insemination
Layering technique male infertility pregnancy outcome spermatozoal abnormal membrane
2008/12/5
This study was designed to evaluate the usefulness of the hypo-osmotic swelling (HOS) test in predicting successful conception and the pregnancy outcome in couples in whom men are affected by mild...
