The giant calculus within the prostatic urethra is a rare clinical entity in the young population. Most of the calculi within the urethra migrate from the urinary bladder and obliterate the urethra. These stones are often composed of calcium phosphate or calcium oxalate.

Investigation of the neural target level of hyperthyroidism in premature ejaculation in a rat model of pharmacologically induced ejaculation.

Introduction: Association between hyperthyroidism and premature ejaculation was demonstrated in clinical studies.

Aim: The aim of this study is to determine the target level of changes on ejaculatory physiology under hyperthyroid states.

Methods: p-Chloroamphetamine (PCA)-induced pharmacologic ejaculation model with 24 male Wistar rats was used in the study.
