Effects of long- and short-term vasectomy on structural and functional parameters of the rat
long- and short-term vasectomy structural and functional parameters rat
2009/2/20
The effects of vasectomy were examined by comparing various parameters from sham operated and vasectomized rats that had undergone surgery at 90 days of age and were killed at 190 or 390 days of age...

Monoclonal antibody (HS-63) raised in mice against human ejaculated sperm, polyclonal antibodies raised in rabbits against the cognate mouse testicular antigen (MSA-63; or Fab) and polyclonal antibodi...
Sperm penetration into a hyaluronic acid polymer as a means of monitoring functional competence
Sperm function tests hyaluronate polymer bovine cervical mucus hamster oocyte penetration test
2009/2/10
The diagnostic significance of sperm penetration assays based on a commercially available hyaluronate preparation (Sperm Select) has been investigated in the male partners of 77 couples characteri...
Functional aspects of human sperm binding to the zona pellucida using the hemizona assay
Human zona pellucida hyperactivation infertility
2009/2/7
The hemizona assay (HZA) has facilitated investigations of sperm function in relation to zona pellucida binding. In this study, the authors examined: 1) the association between hyperactivated sperm ...
Characterization of functional Leydig cells after purification on a continuous gradient of percoll
functional Leydig cells purification continuous gradient of percoll
2009/2/6
Two human chorionic gonadotropin (hCG) responsive cells from rat testicular interstitium were previously isolated on a discontinuous gradient of Percoll. The light cells were non-steroidogenic and...
Effect of Carboplatin on the Functional Integrity of the Human Sperm Membrane In Vitro
Testicular cancer fertility seminoma
2008/12/30
Although it is well known that carboplatin is a drug that binds directly to DNA, causing DNA-DNA and DNA-protein cross-links, which is the presumptive method for killing cells, the whole mechanism o...
Immortalized testis cell lines from estrogen receptor（ER）alpha knock-out and wild-type mice expressing functional ERalpha or ERbeta
Immortalization HPV E6/E7 in vitro models
2008/12/29
The surprising findings that male mice lacking the estrogen receptor (ER) alpha (alphaERKO) have atrophic testis and are infertile proved that ERalpha is involved in normal testicular function. To o...
Functional and ultrastructural features of DNA-fragmented human sperm
DNA-fragmented human sperm
2008/12/25
The functional significance of deoxyribonucleic acid (DNA) fragmentation in ejaculated human sperm is unclear. In this study the extent of DNA strand breakage in swim-up selected spermatozoa was eva...
