Atrial natriuretic peptide（ANP）as a stimulus of the human acrosome reaction and a component of ovarian follicular fluid：correlation of follicular ANP content with in vitro fertilization outcome
Noncapacitated spermatozoa capacitation
2009/2/12
Atrial natriuretic peptides (ANPs) from several species induced the human acrosome reaction. The maximal response was highest for human ANP (18.6% above unstimulated or baseline values) and decrea...
Effects of subchronic treatment with cis-platinum on testicular function, fertility, pregnancy outcome, and progeny
Fertility cis-platinum pregnancy outcome progeny
2009/2/10
Cis-platinum-based chemotherapy is known to impair spermatogenesis, but the effects of paternal cis-platinum treatment on the progeny are unknown. To study this effect, sexually mature male Sprague-...
Long-term outcome following testicular ischemia in the rat
testis ischemia circulatory isolation
2009/2/6
Male germ cells are quite sensitive to interruption in blood flow. Eight weeks after subjection to 45 minutes of testicular ischemia, the spermatogenic epithelium of the rat remains significantly da...
Outcome of Fowler-Stephens Operation for Undescended Testes: An Experimental Study
Cryptorchidism orchiopexy postoperative testicular atrophy inhibin ß B mast cells
2008/12/24
The aim of this study was the outcome of Fowler-Stephens (FS) operations in prepubertal Wistar rats. Thirty-two 30-day-old rats underwent laparoscopic FS procedures on the right testicles (8 of t...
A Retrospective Comparison of Pregnancy Outcome Following Conventional Oocyte Insemination vs Intracytoplasmic Sperm Injection for Isolated Abnormalities in Sperm Morphology Using Strict Criteria
In vitro fertilization zona pellucida subfertile male
2008/12/24
Initial in vitro fertilization (IVF)–embryo transfer studies found poor fertilization and pregnancy rates following conventional fertilization of oocytes when using sperm with <4% normal morpholo...
Effects of the Chemotherapeutic Agents for Non-Hodgkin Lymphoma, Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone（CHOP）, on the Male Rat Reproductive System and Progeny Outcome
Anticancer drugs spermatogenesis male germ cell apoptosis adverse effects developmental toxicity
2008/12/24
Chemotherapy of non-Hodgkin lymphoma (NHL) with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) is associated with significant gonadal damage. Our goal was to determine the impact ...
Concentration of Glutathione and Expression of Glutathione Peroxidases 1 and 4 in Fresh Sperm Provide a Forecast of the Outcome of Cryopreservation of Human Spermatozoa
Oxidative stress freezing thawing sperm motility assisted reproduction
2008/12/22
Oxidative stress imbalance potentially leads to damage of the structure of the cell and macromolecules such as plasma membrane components, proteins, and DNA. The plasma membrane of the sperm cell, w...
5-Aza-2'-Deoxycytidine Induces Alterations in Murine Spermatogenesis and Pregnancy Outcome
DNA methylation 5-azacytidine DNMT DNMT1 mouse fertility DNA methyltransferase
2008/12/19
Because of the ability of cytidine analogues, such as 5-aza-2'-deoxycytidine, to incorporate into DNA and lead to decreases in DNA methylation, there has recently been renewed interest in using thes...
Effect on Clinical Outcome of the Interval Between Collection of Epididymal and Testicular Spermatozoa and Intracytoplasmic Sperm Injection in Obstructive Azoospermia
ICSI fertilization pregnancy surgical retrieval
2008/12/18
We wished to determine whether the interval between surgical retrieval of epididymal and testicular spermatozoa in obstructive azoospermia and their subsequent use in intracytoplasmic sperm inject...
