Disorders of the Male Reproductive System01:20

Disorders of the Male Reproductive System

5.2K
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....

Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

31.1K
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...

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors

818
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...

Penis01:29

Penis

49.9K
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: Prostacyclin Receptor Agonists

613
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Infertility in Males01:23

Infertility in Males

655
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Area of Science:

  • Urology
  • Oncology
  • Sexual Medicine

Background:

  • Cancer surgery, particularly for urologic malignancies like prostatectomy, frequently leads to erectile dysfunction (ED).
  • Disruption of penile blood supply and nerve pathways during surgery is the primary cause of post-prostatectomy ED.
  • Factors influencing post-surgical ED include surgical technique, nerve-sparing status, patient age, and pre-existing health conditions.

Purpose of the Study:

  • To review available treatment options for men experiencing erectile dysfunction after prostatectomy.
  • To assess the efficacy of various therapeutic modalities for post-surgical erectile dysfunction.

Main Methods:

  • Review of current literature on the management of post-prostatectomy erectile dysfunction.
  • Analysis of treatment outcomes for vacuum erection devices, oral phosphodiesterase 5 inhibitors (PDE5I), intracavernosal injections, and penile prostheses.

Main Results:

  • Vacuum erection devices, when used daily post-surgery, demonstrate high efficacy in achieving intercourse-suitable erections.
  • Oral PDE5 inhibitors are a primary treatment, effective across various ED types.
  • Intracavernosal injections and intraurethral therapies serve as effective second-line options, with penile prostheses as a definitive solution for refractory cases.

Conclusions:

  • A combination of daily vacuum erection device use and oral PDE5 inhibitors is recommended in the early postoperative period.
  • For non-responders, alternative treatments like intraurethral alprostadil, intracavernosal injections, or penile prosthesis should be considered.
  • Careful patient selection and counseling are crucial for achieving high satisfaction rates and improved erectile function.
