Natural Cycle IVF with ICSI uses conventional in vitro fertilization procedures without the use of fertility drugs to stimulate egg production. The woman's natural menstrual cycle is monitored through blood tests and ultrasound allowing the specialists to determine the correct time for mature egg collection.
After eggs have been harvested, they are used in conventional IVF treatment or in
IVF with ICSI, where a sperm is injected into the center of the egg to increase the chance of fertilization.
Advantages
Natural cycle IVF treatment is an option preferred by women whose infertility problems are not related to ovulation. Some consider natural cycle IVF with ICSI to be an advantage over drug-assisted IVF because the side effects associated with the
fertility drugs are avoided. In addition, the treatment can be done repeatedly in consecutive months, whereas with regular IVF the patient is advised to wait 3 months before undergoing a further treatment cycle. Natural cycle in vitro fertilization is a more affordable infertility option as fertility drugs are not needed.
The Disadvantage
Fewer eggs are produced during natural menstruation cycles than if ovulation is induced using fertility medication. When less eggs are produced, selecting quality, healthy eggs for use in treatment becomes more difficult. As a result, the success rates of natural cycle IVF are lower then conventional IVF.
