Correlation between in vitro fertilization and human sperm density and motility
Correlation fertilization human sperm density motility
2009/2/23
The conventional sperm characteristics of density (millions per milliliter) and motility, scored in a semi-subjective way, were correlated with results of an on-going in vitro fertilization and em...
Heterogeneity of sperm density profiles following 16-week therapy with continuous infusion of high-dose LHRH analog plus testosterone
sperm density profiles 16-week therapy high-dose LHRH testosterone
2009/2/23
LHRH agonist analogs have been investigated as potential male contraceptives. It has been shown that the LHRH agonistic analog [D-Trp6,Pro9-NEt] LHRH (LHRHA) given to men in single doses up to 500 m...
Heterogeneity of sperm density profiles following 20-week therapy with high-dose LHRH analog plus testosterone
LHRH analog sperm density heterogeneous response
2009/2/20
Eight normal male volunteers received an LHRH analog, 100 to 500 micrograms daily, for 20 weeks. Testosterone enanthate, 100 mg, was given by injection every second week. Sperm density fell to 5.5 X...
Low density lipoprotein receptor-related protein-1 expression in the testis：regulated expression in Sertoli cells
protein-1 testis regulated expression Sertoli cells
2009/2/17
The low density lipoprotein receptor-related protein (LRP-1) is a multiligand receptor capable of mediating endocytosis of a wide array of ligands that relate to both lipoprotein metabolism and pr...
Sperm function and choice of preparation media：comparison of Percoll and Accudenz discontinuous density gradients
Sperm maturity and creatine kinase motile sperm yield sperm activation chiortetracycline
2009/2/16
We compared the sperm populations prepared by Accudenz (35-65%) and Percoll (40-80%) density gradients in 21 normospermic specimens (concentration, 53.6 +/- 3.8 x 10(6) sperm/ml; motility, 44.5 +/...
Comparison of Six Density Gradient Media for Selection of Cryopreserved Donor Spermatozoa
Sperm separation silane-coated silica particles iodixanol donor semen
2008/12/22
The aim of our study was to evaluate the efficiency of 4 density gradient media for motile cryopreserved spermatozoa selection to Percoll (Kabi Pharmacia, Uppsala, Sweden) and to Puresperm (J.C.D. I...
