Repair of experimental varicoceles in the rat. Long-term effects on testicular blood flow and temperature and cauda epididymidal sperm concentration and motility
varicocele varicocele repair rat testis
2009/2/23
The effects of varicocele and varicocele repair on testicular blood flow, temperature, sperm counts, and sperm motility were assessed in adult male rats. The duration of the experimental varicocele ...
Scrotal hypothermia and testicular blood flow in the dog
hypothermia testicle blood flow thermal
2009/2/20
Two clinically tolerable methods of producing testicular hypothermia have been studied in dogs. Evaporative cooling produced a 3.7 degree fall and ice water a 9.7 degree fall in intratesticular te...
Testicular blood flow in young and old rats and influence of hCG
testis blood flow hCG rat aging
2009/2/20
To evaluate the influence of age, testicular capillary blood flow (TCBF) was measured, using the microsphere technique, in rats 3 to 24 months old, under basal conditions and after hCG stimulation (...
Testicular blood flow and fluid dynamics in monkeys with surgically induced varicoceles
varicocele monkey testicular blood flow
2009/2/19
The blood flow rates and ability to remove an added fluid load were studied in the testes of monkeys with surgically induced varicoceles and in sham-operated control monkeys. These studies were conduc...
Pituitary adenylate cyclase-activating polypeptide（PACAP）：effects on blood flow in the testis and caput epididymidis of the rat
blood flow testis caput epididymidis rat
2009/2/18
Pituitary adenylate cyclase-activating polypeptide (PACAP) is synthesized in developing germ cells in the testis and may act as a paracrine modulator of spermatogenesis and/or participate in tubul...
Unilateral injection of neuropeptide Y decreases blood flow in the injected testis but may also increase blood flow in the contralateral testis
NPY innervation
2009/2/18
Neuropeptide Y (NPY) receptors have recently been described in intratesticular arterioles, but the role of NPY in testicular blood-flow regulation has not been examined. To explore this, we admin...
Testicular microvascular blood flow：alteration after Leydig cell eradication and ischemia but not experimental varicocele
Vasomotion testicular torsion rat
2009/2/16
Testicular microvascular blood flow is known to exhibit vasomotion, or pulsatile flow. In the present study we have used laser-Doppler flowmetry to study microvascular blood flow in the rat testis a...
