Antral follicle count Classification [6] Approximate expected response [6] Risks [6] Pregnancy rates [6] Recommendation [6] Less than 4: Extremely low: Very poor or none: Cancelled cycle expected: 0–7% with 1 oocyte [7] Not attempt IVF 4-7: Low: Possibly/probably poor response: Higher than average rate of IVF cycle cancellation: 15% [7] High ...
The SART summarised 2008–9 success rates for US clinics for fresh embryo cycles that did not involve donor eggs and gave live birth rates by the age of the prospective mother, with a peak at 41.3% per cycle started and 47.3% per embryo transfer for patients under 35 years of age. IVF attempts in multiple cycles result in increased cumulative ...
A variety of hormones can be tested at different times in the menstrual cycle to determine the likelihood of different responses to stimulation for In vitro fertilization (IVF). Pregnancy rates in ovulation induction when using antiestrogens, as functions of the size of the leading follicle as measured by transvaginal ultrasonography at days 11 ...
In terms of outcome, "pregnancy" may refer to a positive pregnancy test, evidence of a pregnancy with a "viable" fetus or implantation. Furthermore, pregnancy rates can be influenced in IVF by transferring multiple embryos that may result in multiple births. A strict definition in the IVF setting would refer to the singleton pregnancy rate that ...
Out of in vitro matured oocytes, those fertilised with ICSI have a success rates of 60-80%, compared to IVF with success rates of 25-40%. [16] A few live births have already been made by taking small early tertiary follicles, letting them mature in vitro and subsequently fertilizing them. However, for follicles that haven't reached the early ...
The average age of a girl's first period is 12 to 13 (12.5 years in the United States, [6] 12.72 in Canada, [7] 12.9 in the UK [8]) but, in postmenarchal girls, about 80% of the cycles are anovulatory in the first year after menarche, which declines to 50% in the third year, and to 10% by the sixth.

There are three categories when performing an ultrasound to cheek the antral follicle count: Low follicle count (1-3): low ovarian reserve and increased risk of menopause in the next 7 years. Normal follicle count (4-24): Normal follicle amount for women in reproductive age. High follicle count (>=): High risk of hyperandrogenism.
The ovary is generally thought of as an egg bank from which the woman draws during her reproductive life. The human ovary contains a population of primordial follicles.At 18–22 weeks post-conception, the female ovary contains its peak number of follicles (about 300,000 in the average case, but individual peak populations range from 35,000 to 2.5 million [3]). p The size of the initial ...
