The cervix is the opening to the uterus, so you'd have to go through it to get to the uterus.
the internal OS
The reproductive structure that can deposit sperm at the opening of the uterus is the penis. During sexual intercourse, the penis delivers sperm through ejaculation, directing it into the vaginal canal, which leads to the cervix, the opening of the uterus. This process is essential for natural conception as it enables sperm to reach the uterus and potentially fertilize an egg.
The opening of the cervix is closest to the vagina -- the one you can feel with your finger -- is called the external os (orifice). This os leads into the cavity of the cervix and then into the cavity of the body of the uterus. At the point where the endocervical canal meets the uterus is another opening, called the internal os. .
I believe the answer is prolapse of the uterus.
The outer cervical os is the opening in the uterine cervix (the neck of the uterus) closer to the vagina. Its counterpart is the interior cervical os, which is opening in the cervix closer to the uterus.
