The luteinizing hormone (LH) surge is a critical event in the menstrual cycle, signaling the impending release of an egg from the ovary. It is a sharp increase in LH levels that can be detected through ovulation predictor kits. This hormonal spike triggers a series of physiological processes that culminate in ovulation.
Accurately identifying the timing of this surge is paramount for individuals planning pregnancy or those seeking to avoid conception. Knowledge of this timeframe allows for strategic timing of intercourse to maximize the probability of fertilization. Historically, basal body temperature charting was used; however, LH testing offers a more precise method for pinpointing the fertile window.
