Once every menstrual cycle, eggs are ovulated into the oviduct where they await fertilization. The ovulated eggs are arrested in metaphase of the second meiotic division, and only complete meiosis upon fertilization. It is crucial that the maintenance of metaphase arrest is tightly controlled, because the spontaneous activation of the egg would preclude the development of a viable embryo (Zhang...

Abstract Polycystic ovarian syndrome (PCOS) is a common cause of subfertility particularly when anovulation present.

Measure up to the right goal. A goal that is measurable, achievable, and critical to your bottom line gives your team a “true north” point on its collective compass. Determine that necessary goal—for example, meeting the industry standard to financially clear 95 percent of all elective procedures five days before admission—and then measure your progress with a consistent scorecard of key metric...
