A lower antral follicle count is associated with infertility [PDF]

Fertility and Sterility, 2011
To determine whether infertile women have lower antral follicle counts (AFC) than age-matched normal women.Case-control.Academic center.A total of 881 infertile women and 771 women from the community.Antral follicle count and basal hormone measurements.Median AFCs and FSH levels were compared between the two groups within 5-year age strata by using the

The antral follicle count: practical recommendations for better standardization

Fertility and Sterility, 2010
To provide recommendations for the standardized use of the Antral follicle count (AFC) which is used to predict ovarian response to gonadotrophin stimulation during assisted reproductive technology treatment. However, the nature of the follicles that are visualized by ultrasound and the competence of the oocytes held within are largely unknown.

Effects of Maternal Antral Follicle Count in Bos Taurus Indicus Cattle on the Genetic Merit of Male Offspring and Antral Follicle Count of Female Offspring

Theriogenology, 2023
This study evaluated the effects of antral follicle count (AFC) in female cattle on offspring characteristics. Recently calved multiparous Bos indicus cows (Nelore; n = 222) were evaluated using ultrasonography on random days of their estrous cycle to determine the AFC and were classified into "low" (≤15 follicles), "intermediate" (≥16 and ≤ 29 ...

Is antral follicle count a genetic trait?

Menopause, 2010
The aim of this study was to determine the relationship between maternal age of menopause and antral follicle count.This was a cross-sectional study of 124 women aged 25 to 48 years presenting with infertility. Women reported their mother's age of menopause and underwent transvaginal ultrasound to assess antral follicle count.

Effect of different types of ovarian cyst on antral follicle count

Fertility and Sterility, 2010
We compared antral follicle count in ovaries harboring different types of cysts to the contralateral normal ovaries. Besides endometrioma, the presence of other types of ovarian cysts does not influence the antral follicle count.

Ovarian volume and antral follicle counts as indicators of menopausal status

Menopause, 2001
Recent studies suggest that ovarian volume and antral follicle numbers may be sensitive, specific, and early indicators of menopausal status. The accuracy of these markers, however, has not been compared directly to more traditional markers [age and follicle-stimulating hormone (FSH) levels].

Transcriptomic analysis of heifers according to antral follicle count

Theriogenology
While antral follicle count (AFC) has been associated with higher pregnancy rates, at present, our understanding of it as a reproductive parameter remains incomplete. This study aimed to characterize gene expression profile of oocytes from crossbred Bos taurus x Bos indicus heifers with high and low AFCs.

130 Increased antral follicle population at 60 days of gestation in Holstein cows with low antral follicle count

Reproduction, Fertility and Development, 2019
The antral follicle count (AFC) has been pointed out as one of the main factors that influence the efficiency of reproductive biotechniques. Thus, AFC is considered a fertility marker, which has high repeatability in the same animal. The objective of this study was to evaluate AFC in cows at AI (nonpregnant) and at two moments of gestation (30 and 60 ...

138 Relationships Between Antral Follicle Count, Ovarian Volume, Pre-Antral Follicle Number, and Oocyte Quality

Reproduction, Fertility and Development, 2017
The objective was to evaluate the possible relationships between AFC, ovarian volume, ovarian follicle reserve and oocyte quality in abattoir-derived ovaries (experiment 1) and in cows (experiment 2) submitted to OPU. Antral follicle counts of =25, 16 to 24, and = 16 were used to define AFC classes as high (HAFC), intermediate (IAFC), and low (LAFC) in
