In this study, we evaluated the effects of glutathione (L-g-glutamyl-L-cysteinylglycine; GSH) supplementation of the thawing extender on semen parameters to compensate for the decrease in GSH conten...
Oral administration of sodium tungstate to adult male streptozotocin-diabetic rats for 3 months normalized serum levels of glucose, insulin, luteinizing hormone, and follicle-stimulating hormone. Th...
Our previous observations of changes in the expression of cAMP-dependent genes and the cAMP-responsive element modulator (CREM) in rat testicular cells after spinal cord injury (SCI) implied abnor...
In this study, we evaluated the effects of glutathione (L--glutamyl-L-cysteinylglycine; GSH) supplementation of the freezing extender on semen parameters during the cooling (2 hours at 5°C) and free...
In a previous study assessing tadalafil for the treatment of erectile dysfunction (ED), tadalafil 20 mg was shown to improve erectile function for up to 36 hours vs placebo. This study sought to demon...
Physiological aging is a significant risk factor in the on-set of male erectile dysfunction (ED) and an imbalance in factors that modulate cavernosal smooth-muscle tone may play a role in these altere...
To develop into haploid gametes, germ cells must undergo meiosis, a 2-step cell division process that is characterized by a sophisticated design in chromosome architecture and highly specific dynamic ...
A study was conducted to form a unified hypothesis regarding the gonadotropin-related mechanisms that underlie alterations in the male reproductive system in individuals with diabetes. Streptozotoci...
Human aging is associated with many changes, which resemble those seen with deficiencies of sex steroids or growth hormone and with cortisol excess. Among these are decreases in lean body mass (LBM) a...
Penile erection is a highly specialized vascular biologic process that requires regulatory control. Among the regulatory mechanisms contributing to this regulation, the nervous system is perceived to ...
Recently, we reported that male accessory sex gland (ASG) secretions protect sperm genomic integrity by demonstrating that DNA damage was more extensive in sperm not exposed to the secretions. The p...
To examine the performance of a self-report diary to assess psychosexual function in hypogonadal men, 2 groups of eugonadal men and 2 groups of hypogonadal men were asked to record and score paramet...
The goal of this study was to investigate the effects of medical castration (luteinizing hormone-receptor hormone [LH-RH] agonist treatment) or surgical castration on erectile function in an animal ...
Ten to 15% of reproductive age couples in the United States are not able to achieve a successful pregnancy and are considered infertile. Infertility affects men and women equally. Male fertility r...
Sperm storage via freezing has been useful for men who have difficulty masturbating during assisted reproductive technology (ART) programs and before impotency caused by chemotherapy, vasectomy, and...
