Made of medical silicone, durable, very plastic, safe for the body (made similarly to a menstrual cup). It can be washed in hot water and is reusable. Its structure makes it easier for sperm to stay in the vagina and migrate to the cervix and uterus, which can significantly increase the chances of fertilization. It is most often used by couples who have problems with low sperm count and motility. For reasons of hygiene and discretion, this cup will be delivered to you in a special box and a tiny red bag. Remember to wash the cup in boiling water and dry it before first use and after intercourse. Always keep in a dry and clean place. Operation instructions in a bag.
