Triggering sperm and contractions – what is the connection?
The connection between sperm and the triggering of contractions is currently still too poorly researched to give a clear answer to this question. The assumed connection is that sperm consists to a certain extent of prostaglandins.Prostaglandins are tissue hormones that are found throughout the body and are also involved in inflammation, pain and blood clotting. Prostaglandins are also thought to stimulate smooth muscles, which is also found in the uterus.
Accordingly, prostaglandin-like substances (such as Dinoprostone®) are used in obstetrics to trigger contractions. It is questionable whether the concentration of prostaglandin in the sperm is sufficient to induce labor. It is also assumed that prostaglandins have a positive effect on fertilization by increasing the receptivity of the endometrium.
