After a necropsy of the whales in Germany, researchers found that four of the giant marine animals had large amounts of plastic waste in their stomachs. The chemical composition of the cervical mucus varies with the woman's cycle, affecting the ease with which sperm can penetrate it. In addition, progesterone causes the entrance of the cervix to close dramatically, even though just prior to ovulation it had been gaping in readiness for the entry of sperm. Under the influence of the midcycle LH surge, the wall of the follicle weakens and deteriorates, and a specific site on its surface ruptures. The ratio of water to sperm is quite high and the chances of a sperm making it through the water and into the vagina is low.
