Prima HOME TEST Ovulation LH Test

Throughout the entire fertile age, meaning the period between puberty and menopause, significant structural and functional changes occur in the female reproductive system every month. These changes are due to continuous fluctuations in estrogen and progesterone levels, which are regulated by the hypothalamic-pituitary-ovarian axis. These hormones dictate the menstrual cycle, which is divided into four phases: menstruation, follicular phase, ovulation, and luteal phase. During the ovulation phase, which occurs around the 12th or 13th day of the menstrual cycle, estrogen levels in the blood rise so high that the pituitary gland begins producing luteinizing hormone (LH), leading to the rupture of the follicle and the release of the egg ready for fertilization. The egg can be fertilized within the following 24 hours. Therefore, measuring the concentration of LH in urine is an effective method for optimizing the chances of fertilization. The ovulation LH test allows for the measurement of LH concentrations exceeding 25 mIU/mL, thereby determining the days when the likelihood of successful fertilization is highest.
