Natural Cycle In Vitro Fertilization (IVF) is an assisted reproduction technique that takes advantage of the body’s natural process without using medications to stimulate ovulation. Instead of retrieving multiple eggs, the procedure works with the single egg that the body naturally produces during that cycle.
This approach is ideal for patients who wish to avoid hormone use, have a low ovarian reserve, or simply seek a more natural, less invasive treatment with fewer side effects.
At Advanced Fertility Center Cancún, we offer this alternative as part of our personalized protocols, providing options tailored to each patient’s needs.
Ultrasound observes the development of the dominant follicle in a natural female cycle (follicular monitoring). Medication can be used to induce ovulation at the appropriate time.
The oocyte is captured by ultrasound-guided aspiration in the operating room.
The sperm is trained to fertilize.
The oocyte is fertilized to create an embryo in the laboratory using conventional IVF or ICSI (intracytoplasmic sperm injection).
The embryo is generally transferred fresh, although it can also be vitrified (frozen) for storage and later transfer.
