Condoms are the only contraceptive method that also protects against STIs. Understanding your options and using them correctly maximizes both protection and comfort.
Types of Condoms
Latex condoms are the most common and effective. Polyurethane and polyisoprene condoms are alternatives for latex allergies. Lambskin condoms prevent pregnancy but do not protect against STIs. Internal (female) condoms give women control over protection. Each type has different feel, cost, and compatibility.
Proper Use Technique
Check the expiration date. Open the package carefully without using teeth or scissors. Pinch the tip to leave space for semen. Roll the condom down the erect penis to the base. After ejaculation, hold the base and withdraw while still erect. Use a new condom for each act of intercourse.
Product Compatibility
Latex condoms are damaged by oil-based lubricants, coconut oil, and petroleum jelly — use only water-based or silicone-based lubricants. Spermicides containing nonoxynol-9 can irritate vaginal tissue. Some condoms come pre-lubricated; check that the lubricant does not contain ingredients you are sensitive to.
Why Condoms Support Vaginal Health
Beyond STI prevention, condoms help maintain vaginal pH by preventing alkaline semen from disrupting the acidic environment. This is why some women notice fewer BV episodes when using condoms consistently. Condoms are a hygiene tool as much as a contraceptive tool.
Quick Tips
Store condoms in a cool, dry place — heat degrades latex and reduces effectiveness.
Check the expiration date on every condom before use.
Use water-based lubricant with latex condoms to prevent breakage.
Did You Know?
Condoms are the only contraceptive method that also prevents STIs.
Proper condom use reduces STI transmission by 95–98%.
Condoms prevent semen from raising vaginal pH, protecting the microbiome.
Non-latex options (polyurethane, polyisoprene) are available for latex-allergic individuals.
Key Takeaway
Condoms are the most versatile tool for both contraception and vaginal health protection. They prevent STIs AND protect the vaginal microbiome from pH disruption by semen.
