In-vitro fertilization program includes several important steps, among which stimulation of superovulation, or SSO, is of particular importance.

CCO protocol in IVF is a complex of procedures based on the administration of drugs to stimulate follicle growth in order to obtain reproductive material, i.e. mature oocytes. 

CCO protocol, including selection of drugs and the scheme of their introduction, is developed individually, taking into account the follicular reserve of the body. Highly qualified specialists Delivering Dreams provide individual approach to IVF program and development of CCO protocol, as well as constantly monitoring the follicle growth and endometrium state. It is important to remember that the final result of the in-vitro fertilization program depends on the literacy of the specialist.

TYPES OF IVF PROTOCOLS

There are several types of IVF protocols, which have some differences until the superstimulation stage is completed and the eggs are obtained. Thereafter, they are identical, except in cases where cryopreservation of biological material is required.

Types of IVF protocols differ depending on the range of medications used, the total duration of the stage. Thus, there are short, ultra-short, long, and hyperlong protocols. In addition, in the presence of natural ovulation, a natural protocol is used, which excludes the use of drugs that stimulate follicular growth.

Long and short protocols are particularly common among those used:

• Short IVF protocol. Implies preservation of hormonal background, as well as the use of drugs that exclude the onset of premature ovulation.
• Long IVF protocol. Under this protocol, medications are used to suspend the production of luteinizing hormone. While indicators are decreasing to minimal levels, medications are used to stimulate ovarian activity and follicle growth.
• When developing protocols, the specialist collects and analyzes data on the condition of the reproductive system, the patient’s hormonal background, and peculiarities of the menstrual cycle. This information is needed to select the most appropriate individual program.

SHORT IVF PROTOCOL

The duration of the short IVF protocol is no more than 12 days. In this stage, which starts on the 3rd to 5th day of the menstrual cycle, medications are used to stimulate both ovaries and follicle growth. The protocol is considered successful if both ovaries respond to the therapy used.

It should be noted that in the natural menstrual cycle, the female reproductive system produces one follicle. The production of two or more is considered a rare exception. Since the egg itself is enclosed in the follicle, it is not possible to determine its presence with an ultrasound scan. Microscopes are used as part of this examination if necessary.
