TRPV1 in male reproductive system: focus on sperm function

Area of Science:

• Male reproductive biology
• Molecular and cellular physiology
• Spermatozoa function

Background:

• Transient Receptor Potential Vanilloid 1 (TRPV1) is a receptor involved in pain and heat sensation.
• TRPV1's role in peripheral tissues, including male reproductive organs, is increasingly recognized.
• Evidence suggests TRPV1's involvement in regulating male reproductive functions.

Purpose of the Study:

• To review the expression and mechanisms of TRPV1 in the male reproductive system.
• To highlight TRPV1's role in sperm function, including calcium homeostasis, endocannabinoid signaling, cholesterol metabolism, and thermotaxis.
• To explore the potential link between TRPV1 and male infertility, particularly concerning oxidative and heat stress.

Main Methods:

• Literature review focusing on molecular and cellular perspectives of TRPV1 in the male reproductive system.
• Analysis of studies investigating TRPV1 expression and function in male reproductive tissues.
• Synthesis of research on TRPV1's interaction with the endocannabinoid system and its role in sperm physiology.

Main Results:

• TRPV1 is functionally active in male reproductive tissues and influences sperm function.
• TRPV1 mediates Anandamide's regulation of sperm, impacting calcium influx and temperature sensitivity.
• TRPV1 plays a role in sperm maturation, thermotaxis, and protection against oxidative and heat stress.

Conclusions:

• TRPV1 is a key player in male reproductive physiology and sperm function.
• Understanding TRPV1 mechanisms offers potential therapeutic strategies for male infertility.
• Further research into TRPV1's role in male reproduction is warranted to address infertility challenges.
