Summary
Serotonin (5-HT) influences ejaculation through various receptors. Selective serotonin reuptake inhibitors (SSRIs) can delay ejaculation, with new short-acting SSRIs offering on-demand treatment for premature ejaculation.
Area of Science:
- Neuroscience
- Pharmacology
- Urology
Background:
- Ejaculation involves spinal generators modulated by brain regions.
- Serotonin (5-HT) plays a crucial role in ejaculatory control.
- Specific serotonin receptors (5-HT1A, 5-HT1B, 5-HT2C) have opposing effects on ejaculation.
Purpose of the Study:
- To explore the role of serotonin in ejaculatory control.
- To investigate the mechanisms by which SSRIs affect ejaculation.
- To evaluate the potential of novel SSRIs for premature ejaculation treatment.
Main Methods:
- Review of existing literature on ejaculation neurobiology and pharmacology.
- Analysis of the effects of different serotonin receptor subtypes on ejaculation.
- Examination of the clinical efficacy and application of SSRIs in premature ejaculation.
Main Results:
- 5-HT1B and 5-HT2C receptor activation retards ejaculation.
- 5-HT1A receptor stimulation precipitates ejaculation.
- SSRIs delay ejaculation, requiring chronic dosing for efficacy.
Conclusions:
- Serotonin pathways are critical targets for modulating ejaculation.
- SSRIs are effective in managing premature ejaculation.
- Short-acting SSRIs represent a promising new therapeutic strategy for on-demand treatment of premature ejaculation.

01:23Antidepressant Drugs: MAOIs and Other Agents
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
01:23Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...
01:21Drugs Affecting Neurotransmitter Release or Uptake
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
01:17Male Sexual Response: Erection & Ejaculation
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.

01:28Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs
Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...
01:30Adrenergic Agonists: Therapeutic Uses
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
Allergies and anaphylaxis:...
