Ovidrel injection: Patients using Ovidrel “trigger shot” to schedule IUI should use the following guidleines: o Patients being instructed to take Ovidrel injection will take the injection at 9 pm and schedule their IUI for the second morning following that injection, unless otherwise instructed.
The trigger shot must be administered approximately 36 hours before IVF egg retrieval as the timing is crucial for the success of the entire IVF process. This trigger shot comprises of one of three medications: Urinary derived hCG (hCGu) shot such as Noravel, Pregnyl, and Profasi.
You won't ovulate right away after taking the trigger shot. It typically takes 24 to 36 hours for the eggs to be released after you inject.
After receiving an injection of human chorionic gonadotropin, ovulation can occur between 24-48 hours, with the average time being within 36 hours. Ovulating as early as 24 hours is less likely, however, it can happen and couples should be prepared.
Bottom line. Trigger shots contain the “pregnancy hormone” hCG. They can, well, trigger ovulation and increase your chances of getting pregnant. They're commonly used alongside IUI or IVF treatments.
The ideal follicle size for IVF trigger shots is when two to three follicles have reached about 17 to 18 millimeters in diameter. An ideal IVF follicle size for egg retrieval is typically around 15 to 22 millimeters in size, which falls right in line with the ideal size for an IVF trigger shot.
Trigger shot mistakes: what next? We know it's easier said than done, but if you do make an error with your trigger shot, try to stay calm. Medication mistakes happen. You may run out of needles, the syringe may crack, or you could get that essential timing wrong.
The pregnancy rate with IUI and no trigger shot was 5.8 percent. With the trigger shot, this rate jumped to 18.2 percent. And when the trigger shot was timed with the woman's natural LH surge, the pregnancy rate was an impressive 30.8 percent.
Do eggs grow after the trigger shot? Your follicles will not continue to grow after a trigger shot. The surge that occurs as a result of the trigger is what begins the process of oocyte maturation, which is the next phase after follicle growth.
Ovidrel (choriogonadotropin alfa) is very effective. In studies, this medication successfully caused ovulation in over 91% of people who used it.
Your gynecologist will order a progesterone test around seven days after your prime conception period has taken place. The progesterone test will also confirm whether or not your progesterone levels have increased after you take the HCG trigger shot.
If you take Ovidrel®, we will typically perform your IUI 24 to 36 hours following the injection. Pregnancy rates following clomiphene/IUI typically range from 8% to 12% per cycle.
Eight to 10 days after your Ovidrel shot (or positive ovulation kit) you may have a blood test to measure your level of progesterone. After ovulation occurs, the follicle turns into a corpus luteum which produces progesterone. A blood pregnancy test may be positive as early as 14 days after your HCG shot.

When you are told to do your trigger shot (hCG, Ovidrel), that's your cue to start eating easily digested foods and drinking fluids that contain electrolytes. What are easily digested foods? Clear soups, fruits, salads, vegetables, bran cereals, etc. Anything the body can easily digest.
You may shower, but do not use a bathtub, hot tub or whirlpool for two days. Do not use heating pads or any other form of heat on the injection site for two days.
If a patient has 30 or more mature follicles they could also need to cancel a trigger shot and the IVF cycle if the fertility specialist feels that there is a risk of severe OHSS. Overall, while follicle counts are useful tools in the IVF process, they are not the end of the story in regards to IVF success.
A follicle is a small sac of fluid in the ovaries that contains a developing egg. If the follicle size is between 18-20 mm in diameter, they are considered to be viable for the egg collection. However, sizes greater than 24 are considered too big, the egg within is overmature and is no longer viable.
Taken together, in both fertile and infertile women the fertility potential of oocytes from the right ovary surpasses that of the left ovary.
If your cycle protocol includes a trigger shot, it's important to know that usually the trigger shot contains HCG, the hormone pregnancy tests look for. If you were to take a pregnancy test while the trigger shot is still in your system, you will get a positive test even if you are not actually pregnant.
Most often, it is administered as part of the IVF timeline so we can retrieve all of the mature eggs. However, these shots may also be used as part of less-invasive fertility treatment measures (more on that below).
Injectable treatments known as Gonadotropins, have been noted to increase your odds of multiples by as much as 30%.
Side effects of the hCG injection will mimic pregnancy. Most commonly patients will complain of mild nausea, headaches, fatigue, breast soreness, irritability, abdominal bloating or uterine cramps.
Answer. In my opinion, follicles of >22mm in mean diameter, are much less likely to house viable , 'competent” eggs , post “trigger”. The ideal pre “trigger” measurement is 18-22mm.
When your follicles reach the right size, your doctor will schedule the trigger shot so it occurs roughly 36 hours before your egg retrieval. This gives the eggs time to mature and allows for egg retrieval before ovulation. Your doctor may administer the shot, but most often it can be done at home.
