The male urethra begins at the bladder and runs through the prostate and perineum to the penis, which it traverses as far as the tip. It is divided into a prostatic, membranous and spongy part, and is altogether about 8 inches in length.
I've found some very interesting info on how midwifes believe now that massaging the perineum can increase the risk of tearing.
The baby advanced well and Jane beautifully birthed her 11 lb 12 oz baby girl into my arms with an intact perineum.
It fills the lower vagina and stretches the perineum (the tissues between the vagina and the rectum).
Less common symptoms include prolonged headache, fever, and pain and swelling of the scrotum, scalp, eyelids, lips, ears, backs of the hands and feet, and perineum.
