Some fibers from the ventral cochlear nucleus cross the midline in the trapezoid body. Thus, cells in the superior olive receive inputs from both ears and are the first place in the central auditory system where binaural processing (stereo hearing) is possible. The output of the superior olive travels in the lateral lemniscus.
Delay caused by a short stress time is usually a week or two, then you ovulate normally. However, under continued stress (heavy exercise, malnutrition, etc.) you can be anovulatory for a very long time. If you are having problems in this area, have a look at this book: Fertility, Cycles & Nutrition 4th Edition.
If your period is prolonged one month, which can happen even to women who normally have regular cycles who are sick or under stress, you may not ovulate until day 24. If this happens, you can get pregnant 4 days before you would expect to get your period, if your normal cycles are 28 days long.
