<p>A blocking ring type condom, including a condom body (1) made of resilient material and having a closed end and an open end, and, provided at the tip of the closed end of the condom body, a semen reservoir (2). The inside of the condom body (1) is provided with a blocking ring (3) which is adjacent to the closed end and which forms an integral structure with the condom body. The closed end of the condom body is provided with a diaphragm-type blocking ring, which helps to form, near the semen reservoir, a blocking area which restricts the semen therein, effectively blocking the semen from flowing back and guarding against said flowing back leading to discomfort or to the condom slipping off in the vagina, leading to unintended pregnancy.</p> |
