A member asked:

Is it the motion of sex or the progestaglands in the sperm that cause cervix to rippen/dilate?

A doctor has provided 1 answer

No: Internal Process: Cervical ripening results from a series of complex biochemical processes that ends with rearrangement and realignment of the collagen molecules. A variety of hormones stimulate the chemical reactions critical for cervical ripening: prostaglandin e2 and f2, nitric oxide, tnf, il-1, il-8, matrix metalloproteinases 2 and 9 and others. This is an internal process independent of sperm, motion, and sex.
