Zhewitra 40 Mg belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing muscles in the walls of blood vessels, thus improving blood flow to specific areas of the body, including the penis. This mechanism helps men achieve and maintain an erection suitable for sexual activity. The typical dosage for Zhewitra 40 Mg is determined based on individual needs and health conditions, with effects lasting for several hours after ingestion. Concerns about the impact of Zhewitra 40 Mg on male fertility stem primarily from its effects on sperm quality and quantity. Research on this topic has provided mixed results. Some studies suggest that PDE5 inhibitors may have a minimal impact on sperm parameters such as motility and morphology.
