A Diaphragm is a safe contraceptive for women who do not want to stress their bodies from taking hormones. However, the right application and the right size are decisive for reliability.
What is a diaphragm?

Before intercourse, it is inserted into the vagina and placed over the cervix. In this way, it forms an impenetrable seal that prevents the sperm from entering the uterus.
Since the size and construction of the vagina are different for each woman, the diaphragm is available in nine different sizes with a diameter of six to nine centimeters. To ensure the best possible protection against pregnancy, adjustment by the gynecologist is an absolute must.
Structure, function & mode of operation
The reliability of this method of contraception depends crucially on the Diaphragm rests in the exact position on the cervix. To do this, the cervix is first measured. In order to determine the correct size of the diaphragm, different sizes must be tried in a second step. The largest diaphragm that can no longer be felt after insertion is the right one. Correct fit can be easily checked by feeling the cervix with your finger. It must be completely covered by the diaphragm.
The front end of the diaphragm should be inserted into the vagina 30 minutes before sexual intercourse. To do this, the edges are slightly compressed and inserted deep into the vagina, similar to a tampon. The correct position is between the posterior vaginal vault and the pubic bone, as this completely closes the cervix. To increase safety, it is advisable to rub the diaphragm with a spermicide, a sperm-killing gel, beforehand on the side facing the cervix and on the edges.
If there is an allergy to spermicides, products based on citric acid or lactic acid can be used, which greatly restrict the mobility of the sperm.
After the insertion, the woman should double-check that it is correctly positioned. When the diaphragm can no longer be moved, it is in the correct position and forms a barrier that prevents the sperm from fertilizing the egg. After ejaculation, the diaphragm must remain in the vagina for at least eight hours until all sperm are unable to fertilize.
After that, it should be removed by grasping it with your finger under the front edge and pulling it out. Then it needs to be cleaned thoroughly with water and a mild soap. Anyone who has sexual intercourse several times while wearing them must also apply spermicides, which are inserted deep into the vagina using an applicator.
Medical & health benefits
A Diaphragm is particularly suitable for women who only have sex occasionally and do not want to use permanent contraception, but do not want to hand over control of contraception to men.
A great advantage in use is that the use of a diaphragm has no adverse health effects. Unlike the pill that absorbs hormones, there is no effect on the menstrual cycle. In addition, women get to know their bodies better by introducing and feeling the correct position, which is valued by many as a valuable self-awareness.
Another plus point is that a diaphragm only needs to be used when needed and, due to its size, is easy to transport as it fits comfortably in any handbag. With all the advantages, however, it must be taken into account that the use of a diaphragm should not be used with frequently changing partners, as it does not protect against the transmission of sexually transmitted diseases such as HIV.
In addition, the use of spermicides can increase the susceptibility to cystitis, and the use of spermicides can cause allergic reactions. If the diaphragm remains in the vagina for more than 24 hours, the risk of developing abnormal vaginal discharge or vaginal inflammation increases.
