Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

15.3K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Penis01:29

Penis

20.0K
The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors

454
Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

Disorders of the Male Reproductive System

3.9K
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Nitric Oxide Signaling Pathway01:28

Nitric Oxide Signaling Pathway

6.0K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Pulmonary Hypertension: Classification and Pathogenesis

499
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Area of Science:

  • Urology
  • Vascular Physiology
  • Medical Imaging

Background:

  • Penile erection involves complex hemodynamic changes.
  • Assessing penile vascular function is crucial for diagnosing erectile dysfunction.

Purpose of the Study:

  • To compare hemodynamic indexes of penile cavernosal arteries across different erection phases.
  • To identify the optimal phase for penile color Doppler ultrasonography.

Main Methods:

  • Healthy males received Alprostadil and stimuli.
  • Penile cavernosal artery blood flow (PSV, EDV, RI) was monitored dynamically.
  • Measurements were taken during latency, tumescence, full, and rigid erection phases.

Main Results:

  • Hemodynamic indexes varied significantly across erection phases.
  • EDV and RI differed between tumescence and full erection.
  • PSV, EDV, and RI showed significant changes between full and rigid erection phases.

Conclusions:

  • Penile cavernosal artery blood flow is dynamic during erection.
  • The full erection phase yields the most representative hemodynamic indexes for vascular function assessment.
