Is 20 mm follicle good?
Monitoring the ovarian follicles is part of the fertility treatment process. When your follicles have reached around 18-20mm in diameter they are deemed ready for egg collection.
What is the best size follicle for IUI?
The ultimate goal is to have 2 or 3 follicles reach approximately 18mm in diameter. Once that is the case and once the lining is appropriately thick (>7mm), a patient is instructed to take the “trigger” medication. The “trigger shot” prompts mature eggs to be released in 36-40 hours.
How much endometrial thickness is required for IUI?
The IVF studies suggested an increase in the pregnancy rate with an endometrium >7 mm (3), whereas the IUI studies failed to demonstrate such a relationship (8). Our study confirmed the reduced pregnancy rate in gonadotrophin-stimulated IVF therapies with an endometrial thickness of ≤7 mm.
How many follicles do you need for IUI?
Follicles Needed for an IUI or Gonadotropins Cycle As with Clomid, ideally, you only want one or two follicles to grow to maturity. Injectable fertility drugs (gonadotropins) come with a higher risk of a multiple pregnancy. It’s possible to develop three, four, or even more mature follicles.
What is the optimal follicle size for IUI?
Optimal follicle size. Apart from the number of follicles, the diameter of follicles also affects IUI success. One study reported that patients with a follicle size of 19-20 mm had much higher clinical pregnancy (30.2%), ongoing pregnancy (24%) and live birth rate (24%). 5.
What’s the success rate of an IUI cycle?
Unlike IVF or ICSI, IUI is a more variable procedure that can involve different ovarian stimulation and semen preparation protocols. As a result, the success rate can range from 2% to 22% per cycle depending a variety of factors:
How is controlled ovarian hyperstimulation used in IUI?
Controlled ovarian hyperstimulation is often used in IUI to increase the number of follicles. While more follicles generally improve the odds of pregnancy, they also increase the risk of multiple pregnancy.
Which is better, one follicle or two follicles?
There is abundant evidence that suggested using one or two follicles in IUI is sufficient and safer than multiple follicles. Multiple follicles generally do not improve IUI success but increase the risk of multiple pregnancy and related pregnancy complications.
