What is a Diaphragm?

Let's take a closer look at what a diaphragm is. A diaphragm, also known as a cervical cap or vaginal diaphragm, is a safe and effective contraceptive device for women. It is made of a thin, hemispherical rubber membrane with an elastic metal rim. The outer diameter of the spring coil ranges from 50mm to 80mm, with 7 sizes including 50, 55, 60, 65, 70, 75, and 80. Chinese women typically use the 65 size, with 70 and 75 being other common options.

Function: The diaphragm, along with spermicidal cream applied before insertion, acts as a barrier to prevent sperm from reaching and fertilizing an egg. The spermicidal cream can kill or inactivate sperm.

How to Use a Diaphragm?

As a contraceptive tool, here's how to use a diaphragm:

Measure the distance between the posterior fornix of the vagina and the posterior margin of the pubic symphysis to determine the appropriate size of the diaphragm. It's best to have a doctor help you with this selection.
Check for any damage to the diaphragm and apply a small amount of spermicidal cream (which kills sperm) to the rim.
In a semi-reclining or squatting position with legs slightly apart, insert the diaphragm into the vagina using your left hand to separate the labia and your right hand's index, middle, and thumb fingers to form the diaphragm into a strip. The posterior rim should rest against the posterior fornix, with the anterior rim covering the cervix.
Remove the diaphragm 8-12 hours after sexual intercourse by hooking the rim behind the pubic bone with your index finger and gently pulling it out. Clean and dry it with warm water or soap and store it in a clean, dry container with talcum powder for future use. Vaginal diaphragms can typically be reused for up to two years. Avoid contact with oil-based products (like Vaseline) to prevent damaging the latex.

Advantages and Disadvantages of Diaphragms

Advantages:

Safe and non-hormonal, requiring no pills or injections.
Long-term use does not impact health or sexual function.
Research shows lower rates of sexually transmitted infections and cervical cancer among women using diaphragms.

Disadvantages:

Less popular due to the inconvenience of use.
Not suitable for women with vaginal infections, severe cervical erosion, uterine prolapse, tight or loose vaginal walls, or habitual constipation.
Not recommended for women allergic to rubber or unable to properly insert the diaphragm.

Effectiveness of Diaphragm Contraception

The diaphragm is a reusable vaginal contraceptive device that requires medical assistance for proper use. It prevents sperm from entering the uterus and fertilizing an egg. For women who have never been pregnant, the effectiveness rate of the diaphragm is 86%, with 14 out of 100 women experiencing an unintended pregnancy per year. For women who have been pregnant, the effectiveness rate drops to 71% due to challenges in properly fitting and maintaining the diaphragm's position during sexual intercourse.
