If I have follicles in both ovaries, but only one is dominant, will hcg shot cause multiple egg ruptures or only the mature one will release egg?

If I have follicles in both ovaries, but only one is dominant, will hcg shot cause multiple egg ruptures or only the mature one will release egg?

Only one: As follicles grow, they develop receptors for the trigger shot. If a follicle has not grown enough, it will not respond to the trigger shot. Usually only the dominant follicle will ovulate unless multiple other follicles have been stimulated. ...Read more

Ans: You are so young. Why are you breaking this down so scientifically. A rupture is not an I ulation. Why don't you take a home pregnancy test? I assume you are sexually active though you don't give a good history. I think you would be less anxious if you just saw your doctor and had a good exam ...Read more

By mistake nurse injected me HCG injection instead of Fostimone, my follicle was 14mm. Doc said IVF to be canceled. Will I have late period or cyst?

By mistake nurse injected me HCG injection instead of Fostimone, my follicle was 14mm. Doc said IVF to be canceled. Will I have late period or cyst?

Uncertain: There is no real reason to think that either of the two things that you mention would occur. If you have regular periods you will likely have one near your usual time. There is no reason to think that you would develop a cyst unless you already had one. ...Read more

How long before a double IUI would you be given HCG shot. And what should be my follicle size. They had me injected when is was 16mm?

IUI: An HCG shot is usually given 24-48 hours after IUI. However, your follicle should have been bigger before the IUI to begin with. Usually IUI is best done when you have a positive LH surge. A follicle size of at least 3.0 cm is encouraging. ...Read more

I'm given hcg shot at cycle day 9 for a 19mm follicle. Doc prescribed Primolut (norethisterone) from day 19 for 7 days. Can it harm possible pregnancy

Very low risk: Nothing has a zero risk, but this would be a very low-risk plan of action. It might be a bit more conventional or appropriate to use micronized progesterone rather than the synthetic (norethisterone,) you could discuss this with your prescribing doctor. Good wishes. ...Read more

At what follicle size should an hCG trigger shot be administered in a medicated cycle?

Depends: Usually ultra sound is by the vaginal route these days. If abdominal ultrasound is performed then the follicles are usually approximately 2 mm smaller. On Clomid (clomiphene) or Femara I usually trigger ovulation with HCG approximately 18 to 20 mm. With gonadotropins I normally trigger ovulation around 20 -21mm. Patients with pcos or polycystic ovarian syndrome triggering ovulation needs to be somewhat later at approximately 21 to 22 mm. ...Read more

Does the hCG trigger shot make you release all follicles or only all of the mature follicles?

Does the hCG trigger shot make you release all follicles or only all of the mature follicles?

Varies: Any follicle that has been recruited to mature, usually only one per cycle, will likely be stimulated to ovulate in rsponse to the HCG "trigger shot". If there has been pretreatment with ovulation inducing drugs, then multiple follicle release is possible. ...Read more

If you have multiple follicles and you have the hCG trigger shot. Do all the follicles ovulate at the same time?

COH and HCG: Hcg will cause you to ovulate more than 1 mature follicle. So if you have multiple follicles and took hcg, you would increase your chance for conceiving but would also increase the risk of multiple pregnancy and of ohss. ...Read more

My follicle is 17mm on day 15 but I didn't ovulate my cycle is 28 and regular can I use choriomon (HCG) 1000 Iu on day 17 for ovulation?

My follicle is 17mm on day 15 but I didn't ovulate my cycle is 28 and regular can I use choriomon (HCG) 1000 Iu on day 17 for ovulation?

Wait longer: Here in the U.S. we typically wait until the follicle reaches 18mm or higher before we trigger ovulation. If they repeat the sonogram in 1-2 days the follicle will likely have reached that goal. I also recommend 5000iu at a minimum to trigger. Why not use the full 10000iu to trigger? It's not like you can save the leftover medication for a future month. It won't last that long even kept cool. ...Read more

Taking 2.5 mg of femara (letrozole) & on cycle day 16 still no follicles. Wht's a normal follicle size and when should they appear? Whn cn I take the hCG shot?

Taking 2.5 mg of femara (letrozole) & on cycle day 16 still no follicles. Wht's a normal follicle size and when should they appear? Whn cn I take the hCG shot?

Around 18, midcycle: A mature follicle is around 18 mm but may not release until about 26 mm. It is normal to have a mature follicle somewhere between days 11 and 14 though it can take longer. Your doc will not instruct you to take the HCG until at least one follicle is mature. ...Read more

IVF egg removal. 32 follicles only 7 eggs retrieved. Did Lupron (leuprolide) trigger and Hcg. Why so few?

Ask your doc: Many possibilities: incorrect timing (too early OR too late) or administration of hCG, bad batch of hCG, surgeon had difficulty with TVA, maybe only 7 mature follicles and the others were mid-to-small...your doctor and your embryology team are only ones who can answer what happened. Good luck with the 7, sounds good! ...Read more

Low Progesterone: Seems like there might be low progesterone levels.
check levels and get progesterone supplementation to get cycle.
next IUI you should be treated with vaginal progesterone after IUI. ...Read more

At this point: You do not need a trigger shot: the progesterone of 8 indicates you already ovulated a few days ago, so the trigger will not do anything useful at this point. Congratulations. ...Read more

Cd 13 hCG trigger, cd 15- 22mm follicle seen with crenations. And IUI done 3hrs later. When should I take the hpt? Does it look like a good cycle?

Doctors instructions: If you just went through bhcg injections and IUI then I find it very surprising if your treating physician did not provide any specific instructions on when they would like to see you again for a pregnancy test. Follow their instructions. If none were given then check a test if you miss your period. ...Read more
