• abstinence
• Refraining from sexual intercourse
• condoms
• A physical barrier that prevents the passages of sperm from the penis to the vagina
• outercourse
• Refraining from sexual intercourse, but perhaps allowing for other methods of sexual release.
• vasectomy
• withdrawal

  

• Male Contraception – Vasectomy

vasectomy
 
What it is…..

• Reversible
• Fast Procedure (done in dr. office in 15 minutes)
• Quick recovery (3 days)
• Cheaper than babies
• Cheaper, less invasive and faster recovery than the female equivalent (tubal ligation)

 
 
What a vasectomy does NOT do….

• does not change
• Erections
• Sexual performance
• Amount of fluid discharged

 

VASECTOMY
