Injecting the HCG injection is a whole process and not a simple jab injected into the body. At first, the doctor will collect a few essential alcohol wipes, syringes, needles, liquid HCG, and bandages. Second, the doctor needs to wash the hand correctly; if this step is ignored, the bacteria may enter the body while injecting; after washing, gloves must be worn. Third, the doctor may ready the syringe by filling the HCG and remove any air bubbles that may be present; last, the doctor pulls the skin by an inch and injects the HCG.

After the body receives the HCG, it starts making and releases the progesterone in the body; the hormone causes obtaining an egg fast and within twenty-four hours. There is a misconception about the HCG injection as many women think it realizes a sudden hormone discharge, and the egg is received. Still, the HCG injection is only usable when a follicle or a sign of the egg releases the HCG injection, releases the hormone, and fastens the fertilization process. After the injection, the body receives the egg within twenty-four hours, and the women are ready to conceive after the sperm is met with regular egg fertilization.

The start of a new cycle begins after approximately two days of the previous cycle is completed. After the start of the new cycle, it is advised to start HCG within two weeks. If two weeks are over, then it is not recommended to start HCG.

Why Does It Take That Long After Cycle To Start HCG?

After the women receive the HCG, every woman reacts to them differently, and not all women can take twenty-four hours to release the egg. Two major factors affect fertilization that is the degree of fertilization and the age group. Age plays the most dominating factor in age; women get closer to hormonal changes and menopause; therefore, the egg release gradually slows.

When the HCG is injected into women of nearly a young age, the body positively takes the hormones, and the egg release is fast, but as the aged women have already hormonal changes, the body may not react to the HCG. Henceforth the body may require more HCGs that can trigger the hormones and can add up to time. It also depends upon the degree of fertilization; if the degree is very high, then the body may not take the HCG positively, and the women may require more doses of HCG.

It takes that long after the cycle to start HCG because of the hormonal changes in the body. As more doses are required, this adds up to the actual time, whereas, if the degree is average, the body can react to HCG and release the hormone that decreases the time to receive the egg. It shall be noted that the HCG may also have side effects that are fatigue, bloating, irritability, restlessness. But with time, the body gets used to the HCG and excess hormone release, and the body adjusts itself.


Overall, it can be concluded that as medical science has evolved, even fertilization can be treated today with the HCG doses that increase the hormone in the body can fasten the release process in the egg. The egg may take twenty-four hours to reach the uterus, but two major dominating factors can affect the time: the woman’s age and the degree of fertilization.

On average, HCG injections are advised to be taken within two weeks after the cycle starts. The HCG cannot trigger the releases just after the injection, but there is a need to have ovary follicles in the body. Only then do the hormones react. Common side effects may be a headache, bloating, and restlessness.
