Penile fractures are classically described as presenting with rapid detumescence of an erection associated with blunt trauma. This clinical finding is due to a tear in the tunica albuginea surrounding...
Intra- and inter-technician variability in assessing sperm motility by the methods recently advocated by the World Health Organization (WHO) were studied. The intra- and inter-technician variability...
Adult male rats were treated with a single dose of 650 mg/kg methoxy acetic acid to deplete the seminiferous tubules specifically of pachytene and later spermatocytes. The effect of this treatment a...
beta-adrenergic receptors were localized and characterized in control and cryptorchidized rats to investigate further their role in testicular function. Slide-mounted cryostat sections were incubate...
Plasma androgen levels studied following the injection of the opioid agonists morphine sulfate (0.5-1.0 mg/kg), beta-endorphin (10-20 mg/kg), and [D-Ala2, D-Leu5]-enkephalin (DADLE; 5-20 microgram...
Chemotherapeutic agents, as well as acetyl-salicylic acid, heparin, and indocin, were evaluated in regard to their effect on the rate of metastasis in the androgen-insensitive Noble rat prostate a...
Isolated rat testes perfused in closed circuit with albuminated Krebs-Ringer bicarbonate buffer were examined by light and electron microscopic techniques in order to assess the structural integrity...
The effects of hypophysectomy and various hormonal treatments on rat testicular prostaglandin dehydrogenase (PGDH), 13-PG reductase, and total PGDH activities were studied in vivo and in vitro. Al...
In 91 male rats, silver or platinum coils were implanted into the vasa deferentia with the hope of developing a simple and reversible method for male fertility control. The insertion of the coil by ...
The objective of this study was to determine the effects of pituitary hormones (luteinizing hormone [LH], follicle-stimulating hormone [FSH], growth hormone [GH], and prolactin [PRL]) on interstit...
Descent of the testes is a complex event mediated by hormonal and mechanical factors. At present we hypothesize that testicular descent occurs as the result of the secretion of descendin from a no...
The authors describe the occurrence of high levels of S-adenosyl-L-methionine decarboxylase (SAMDC) activity in the rat epididymis, and its ontogeny and androgenic control. As early as 15 days of ag...
Spermiation, the release of late spermatids from the Sertoli cell, is disrupted by a number of toxicants. Control of the spermiation process, and the proteins that interact to adhere mature spermati...
A total of 28 donor semen samples were used to evaluate the characteristics of laboratory variability in measuring reactive oxygen species (ROS). The objectives of this study were to assess the intera...
In this age of evidence-based medicine, there is nothing more important than the quality of lab tests (Westgard and Darcy, 2004). However, reliability of semen analysis has been suspected for lack o...
