  • Introduction: Ovulation disorder is the main cause of female infertility. We investigated the use of continuous body temperature monitoring with a vaginal biosensor to improve standard diagnostic methods to indicate ovulation inefficiencies. Biphasic basal body temperature (BBT) rates during the menstrual cycle have been reported and studied since the early 1900s. As the body's core temperature during resting state, BBT is usually assessed by measuring oral, rectal, or vaginal temperature immediately after waking up and before any physical activity. BBT fluctuates in response to hormonal changes during the menstrual cycle for most women. A woman's BBT reaches its lowest point (nadir) in a certain process around her fertile window, just before ovulation and corresponding to the peak of estrogen. Therefore, we define the fertile case or the time frame in which conception can occur. Consequently, we describe the fertile window, or time frame in which vision may occur, as the five days closest to ovulation and the time of ovulation. The chance of getting pregnant again after ovulation is greatly reduced, which means that eggs can only survive for 12 to 24 hours without fertilization. Therefore, a decrease in BBT may indicate impending ovulation. After ovulation, a woman's BBT is usually boosted by increased progesterone levels.
  • Methods: In the forthcoming systematic review, the required data were collected using keywords and citing valid databases such as Scopus, PubMed, Google Scholar and ProQuest. The statistical population includes all studies conducted until 2022 in the field of Women's pregnancy with the method of ovulation biometry. After reviewing the relevant findings and evaluating the quality of the data, 15 articles were analyzed.
  • Results: the finding of ovulation Ovulation was detected in 47 women using cycle monitoring and promotion of progesterone levels to over five nmol/l, reconnoitering the luteal stage. Three women had anovulatory processes; no ovulation was found even after prolonged cycle monitoring with repeated controls. The luteal command was not repeated in one woman with delayed follicular maturation and, presumably, late ovulation. Due to the lack of data, it was impossible to distinguish luteinized unruptured follicle syndrome from luteal insufficiency in this woman. The short luteal phase was found in seven women, low progesterone levels in nine, and both values were unusual in three women. The temperature turns of women with signs of LPD demonstrate statistically considerable differences compared to the group of women with typical luteal phase processes.
  • Conclusion: Continuous body temperature monitoring with a vaginal biosensor can lessen the standard diagnostic procedures used to characterize ovulatory inefficient, especially if dysfunction is due to luteal phase deficiency and polycystic ovary syndrome.
