What is the maximum size of follicle for ovulation?

The maximum follicular diameter prior to ovulation was 21.0 +/- 3.48mm with a range of 15-28 mm. The maximum pre-ovulatory size in the group of infertile patients 21.4mm (range 15-28 mm) was not statistically different from the size in normal volunteers 20.8mm (range 15.5-27mm) (P > 0.05).

Can I get pregnant with 16mm follicle?

16mm were highly effective as were follicles with FD ¼ 16mm: 31% resulted in a conception, whether they were described as FDMax or not. Follicles with dia- meter of 15 mm showed an 8% attributable implantation rate. This was a statistically significant reduction (P , 0.001) in efficacy.

What if the follicle size is too big?

Once ovarian follicles grow to an appropriate size, a trigger is administered to mature the oocytes in preparation for oocyte retrieval. … Furthermore, once ovarian follicles grow too large, follicles may contain oocytes that are “post-mature” and also not competent for fertilization (2).

Can I get pregnant with 18mm follicle?

At >18mm, premature luteinization apparently negatively affects oocyte quality and pregnancy chances, while <16mm (ver), egg quality likely suffers from insufficient cytoplasmic maturation, a characteristic of small follicles.

Can I get pregnant with 12mm follicle?

Conversely, in a prospective study including 9,933 follicles from 535 IVF cycles, it was observed that oocytes from follicles with volume <1 ml (<12 mm diameter) had a significantly lower fertilization rate than oocytes from larger follicles, but when fertilized they yielded embryos of comparable quality; in fact, no ...

What is the normal size of a follicle?

about 18-28mmIn a normal menstrual cycle with ovulation, a mature follicle, which is also a cystic structure, develops [2]. The size of a mature follicle that is ready to ovulate is about 18-28mm in diameter.

Can I get pregnant with a 14mm follicle?

In the knowledge that, in fecund cycles, follicles with a diameter of 15 mm have an 8% chance of producing a viable implantation, and that 14 mm follicles show a much reduced incidence (4%), we would recommend that cycles be cancelled when there are more than two follicles present whose diameters are ≥15 mm at the time …

Can I get pregnant with 17mm follicle?

Leading follicle size was 17mm in 25.6%, 18mm in 42.6%, 19mm in 19.7% and 20mm or greater in 12% of cases. Mean rate of successful egg retrieval was 90% in all cases. Clinical pregnancy rates were 32.6% (17mm), 30.4% (18mm), 44.1% (19mm) and 34.2% (20mm).
