This can be due to two reasons: (1), the follicle itself can "luteinize" but fail to release the egg, a phenomenon known as the luteinized unruptured follicle syndrome (LUFS)--which is actually kind of a controversial topic, or (2), after the egg is released, the corpus luteum is left behind (a collection of cells that produce hormones necessary to sustain an implanting pregnancy). It is very difficult to tell what's a corpus luteum (C.L.) and what's not on ultrasound. Oftentimes a C.L. has some internal debris that is visible on ultrasound, or the walls are not perfectly round, but sometimes it just looks perfectly round and clear. The difficulty in determining if someone has actually ovulated is apparent when you look at all the different ways we try to determine that--basal body temperature charts, urinary LH predictor kits, ultrasound, serum progesterone measurements, etc. This leads to the saying "the only true proof of ovulation is a pregnancy!"

With LUFS you can get an increase in progesterone (which is what causes the temperature elevation), or it could be that you actually have a nice pretty corpus luteum there. Usually in a situation like this I will get follow-up ultrasounds every day or two to watch the appearance of the "follicle," as well as checking blood levels of progesterone. Some docs use serial shots of hCG [the pregnancy hormone that doubles as the body's LH when we want it to :-) ] to help release the egg.
