Male sexual function


Acute application of T to guinea pig ventricular myocytes, suppressed a depolarizing current, I Ca,L , and enhanced a repolarizing current, I Ks , resulting in shortening of the duration of ventricular action potentials. Functional recovery from spinal cord injury could be achieved by interventions that re-innervate disconnected systems or promote the natural plasticity of the central nervous system to facilitate the actions of surviving neurons that have retained axonal connections with their targets [16]. Given the diurnal fluctuations in testosterone, laboratory evaluation of hypogonadism should start with measurement of morning total testosterone level Bhasin et al. Therefore, it is not surprising that cardiovascular disease is a major risk factor for ED. Interventions to produce functional improvements in spinal cord injury include repetitive transcranial magnetic stimulation to the motor cortex [17] , tele-rehabilitation using functional electrical stimulation together with exercise and weight-assisted treadmill walking therapy [18,19] , which result in improved functional outcome of upper limb function and changes to sensorimotor systems. Blood-filled lacunar spaces are essential for erection. In mammals, only a membrane receptor for progesterone has been cloned, but its functional characterization is not yet known.

However, how extensively ARs mediate vascular androgen effects it is not yet known, nor is the full spectrum of specific target genes that are regulated by these receptors. Given the diurnal fluctuations in testosterone, laboratory evaluation of hypogonadism should start with measurement of morning total testosterone level Bhasin et al. Expression of Ca v 1. However, it is not yet known how extensively ARs mediate vascular androgen effects, as well as the full spectrum of specific target genes that are regulated by these receptors.

In mammals, only a membrane receptor for progesterone P has been cloned, but its functional characterization is not yet known. Low, in Primer on the Autonomic Nervous System Third Edition , Reproductive System In the male, sexual function is affected, especially in the early stages, with both erectile and ejaculatory failure. Female sexual function has not been as well studied in these circumstances, although it seems to be affected to a similar degree as in men.

Description:The cavernosal artery, a branch of the penile artery, supplies the lacunar spaces through multiple branches. Activation of these nerves causes vasodilatation and engorgement of the penile musculature and sinuses. The penis is supplied by the internal pudendal arteries, which become the penile arteries. Non-transcriptional regulation of cardiac repolarization currents by T was described by Bai et al. It is important to remember the role of medication-induced ED as this can be a reversible cause. Pathophysiology and Risk Factors The ability to have and maintain an erection is a vascular event.
