Kisspeptin-54 is essential for human fertility as it is involved in the surge of luteinizing hormone and the maturation of oocytes. Studies have shown that a mutation inactivating the kisspeptin signal leads to infertility in women as there is no surge in the level of luteinizing hormone and so oocytes are not matured and released. In this study 53 women were injected with Kisspeptin-54 following superovulation; it was hoped that the Kisspeptin-54 would cause a surge in LH resulting in oocyte maturation. After 36 hours the oocytes were retrieved transvaginally, their maturation state was assessed and they were fertilized by intracytoplasmic sperm. Embryos were then formed from the fertilized oocyte. It was discovered that an injection of Kisspeptin-54 can increase the mean number of mature eggs produced by each patient and that it can induce oocyte maturation in patients with subfertility who are undergoing in vitro fertilization. In 92% of the patients who were given the Kisspeptin injection the oocyte was fertilized and the subsequent embryo was successfully implanted in the patient’s uterus.

One of the stages of IVF is superovulation, this is where multiple oocytes are stimulated to mature by injecting hormones into the patient. This study is proposing to adapt the levels of hormones used in superovulation for each patient so that the optimum number and size of oocytes is achieved. A mathematical model was constructed which predicted the dose of the hormones that would result in the optimum number and size of oocytes. The model was applied to real patients and the resulting oocytes were analyzed to see if the optimum oocytes were produced. The results showed that there were more oocytes and better sized oocytes when the levels of hormones were altered for each patient in comparison to the normal method where the hormone level is the same for each patient. This will improve the success of superovulation cycles and reduce the cost of excess medication.
