Do sperm live for five days

To do this means you must be able to predict when you will ovulate, a task that is sometimes more difficult than you might think. Before we embark on a discussion of how to pinpoint your fertile window, it might be helpful to briefly review the stages of your menstrual cycle , as hormonal changes that occur during the different phases set the stage for ovulation and provide clues as to when ovulation is coming. For example, many women know ovulation is just around the corner when they see an increase in production of fertile-quality cervical mucus. This allows the OvaCue to identify the hormonal changes that occur during the ovulatory process, thereby allowing it to predict and confirm ovulation. This hormone helps build the lining of the endometrium, facilitates the secretion of fertile-quality cervical mucus which helps to protect and transport sperm through the reproductive tract and triggers the production of the luteinizing hormone LH. Conception probabilities have been found to be significantly different from zero from five days before ovulation to the day of ovulation itself. However, the model is biologically unrealistic because it assumes that all ova can be fertilized and lead to a viable pregnancy.
