Personalized Insemination Treatment Study

Study medication dosage for the first insemination cycle will be based on the woman's age as well as her Anti-Mullerian Hormone (AMH) levels.

Study medication dosage for the second and third insemination will depend on ovarian response (number of follicles) during previous insemination cycle and woman's age
