The present invention aims to provide a cervical canal sealant that can be used as a sealant to stop bleeding in the uterus and vaginal discharge, particularly, a cervical canal sealant that can block the cervical canal to inhibit amniotic fluid leakage and that can also be peeled off without damaging reproductive tissue. The present invention relates to a sealant for reproductive organs in which a cured product (X) at 25°C has a storage modulus G' of 200 to 2,000 kPa, the cured product (X) being a cured product obtained by curing the sealant for reproductive organs to a thickness of 120 to 150 µm.
The present invention is directed to providing a safe medical adhesive, a cured body of which is hard to be degraded and decomposed and thus stable and the cured body generates less amount of acid, aldehyde, etc. due to degradation/decomposition. The medical adhesive includes a hydrophilic urethane prepolymer (UP) obtained by reacting a polyisocyanate component (A) containing a fluorine-containing non-aromatic polyisocyanate compound (A1) as an essential ingredient and a polyol component (B) containing a hydrophilic polyol (B1) as an essential ingredient, wherein a chlorine content in a chlorine-containing organic compound based on the weight of the hydrophilic urethane prepolymer (UP) is 0.005 wt % or less.
