HCG injection is a vital hormonal medication used in the IVF (in vitro fertilization) process.
HCG stands for human chorionic gonadotropins. These are hormones that are produced by the placenta and help widely with fruitful pregnancies.
HCG injections are administered optimally to induce follicle growth and egg rupture to have a successful IVF cycle.
Symptoms of Egg Rupture After hCG Injection
- Symptoms of egg rupture after HCG injection may include increased body temperature, spotting, abdominal swelling, pelvic pain, increased libido, among others.
After the administration of the hCG injection egg rupture takes place in the next 48 hours, especially around 36 hours. This period is linked to many symptoms due to the intake of hCG shots.
Some of the symptoms include:
- Increase in body temperature
- Spotting due to rupture of the egg
- Abdominal swelling
- Mild abdominal and pelvic pain
- Increased libido
- Change in cervical mucus texture
- Heightened sense of smell
- Change in breast feel
The symptoms encountered after hCG injection differ from individual to individual. Not all symptoms occur in a person.
Some may experience little to no symptoms even after the hCG shot. This means that the level of HCG is either decreasing or rising very slowly.
Role of HCG injection in IVF
- HCG injection is essential in IVF for inducing follicle growth and egg rupture.
HCG hormones have a similar structure to that of Luteinizing Hormone (LH) and help with ovulation.
Fertility doctors use this injections to stimulate the ovaries and control ovulation during the IVF process.
It helps increase the level of progesterone and the size of the follicles. When the follicles reach an optimal size of around 16 to 22 mm hCG injection is administered to induce ovulation.
HCG also helps in strengthening the uterine lining for successful embryo implantation.
HCG Injection and Egg Rupture
The follicles do not release eggs immediately after the administration of the hCG injection. A dose of 10,000 IU is more commonly given to trigger egg rupture and ensure proper follicle maturation.
According to a study published in the National Library of Medicine, egg rupture typically takes place around 38 hours after the hCG shot.
If you do not encounter any of the above symptoms after 72 hours of the hCG shot and feel like ovulation has not begun, contact a fertility specialist near you immediately.
One of the reasons for egg rupture does not happen after the hCG shot is because of hormonal imbalance. Upon examination, your fertility specialist will take the necessary medical initiatives to create a conducive environment for egg rupture.

why egg not rupture after hcg injection
After an HCG injection, many expect the egg to rupture and be released from the follicle, but this does not always happen. Several factors can contribute to this issue:
- Hormonal Imbalance: If there are imbalances in hormones such as LH or FSH, the body may not respond adequately to the HCG trigger.
- Poor Follicular Development: If the follicles are not fully mature, they may not respond to the HCG injection, preventing ovulation.
- Luteinized Unruptured Follicle Syndrome (LUFS): In this condition, the follicle may luteinize (transform into a corpus luteum) without releasing the egg.
- Timing of the Injection: If the HCG injection is administered too early or too late, it may not align with the body’s natural ovulation cycle.
When to Test for Pregnancy After hCG Injection?
- Pregnancy test should be taken 14 days after the HCG injection for accurate results.
Take a pregnancy test 14 days after taking the hCG injection. The level of hCG in the blood or urine is often detected to test for pregnancy.
Taking pregnancy tests immediately after hCG injection can mislead with false positive results as the hCG level will be on the surge.
For accurate pregnancy results, take a pregnancy test after two weeks of taking the hCG shot.
Conclusion
HCG injection plays a crucial role in aiding the IVF process. The timing of hCG injection administration is synced in a way to aid ovulation.
This will help the doctors to monitor ovulation and collect the eggs at the right time. You can look for the above-listed symptoms that accompany ovulation after the hCG injection administration.
Symptoms or no symptoms always consult your fertility specialist after a few of hCG administration to ensure that the ovulation process is taking place as planned for the IVF process.

FAQs
HCG injection often helps with ovarian stimulation and strengthening the uterine lining. However, if pregnancy does not occur, it is due to issues of egg and sperm quality and other fertility or implantation process factors.
Ovulation takes place around 24 and 48 hours after hCG administration. So the first few days following hCG injection administration is the best time to conceive. Around this time hCG also causes an increase in sex drive. But if you are under IVF or other ART (Assisted Reproductive Techniques) supported conception system, you may have to stay away from intercourse unless otherwise prescribed by your fertility doctor.
If the eggs do not rupture after hCG injection, the follicles turn into cysts. It is not harmful or painful. You may have to consult your fertility specialist regarding the occurrence of no egg rupture if you are under IVF treatment
Eggs may not rupture after a 10,000 IU hCG injection due to factors like hormonal imbalances, insufficient follicular development, or conditions such as Luteinized Unruptured Follicle Syndrome (LUFS). If ovulation does not occur, it’s essential to consult a fertility specialist for further evaluation and guidance.
