High physical activity and ovarian reserve: a prospective study of normo-ovulatory professional athletes.
Observational study in Journal of ovarian research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study investigated whether high physical activity affects ovarian reserve in normo-ovulatory, reproductive-age women.
methodsThis prospective, observational study compared 31 professional female athletes, with 31 women who did not engage in physical activity. It was conducted 2017-2020 in a tertiary medical center. Normo-ovulatory, professional athletes, ages 20-35 years were recruited from The Wingate Institute-the Israeli National Institute for Sport Excellence. They had high International Physical Activity Questionnaire (IPAQ) scores. Non-physically active women, matched by age and body mass index, were recruited from hospital staff. Women were evaluated for ovarian reserve markers on day 2-5 of the menstrual cycle, including follicular stimulating hormone, antral follicle count, anti-Mullerian hormone and Inhibin B.
resultsThe average age of the high physical activity group was 29.9 ± 4.2 years and the nonactive group 31.6 ± 4.2 years (p = 0.062). Body mass index of both groups were similar (22.5 ± 5.0 vs. 21.4 ± 2.5, respectively; p = 0.1). No differences were observed with respect to follicle stimulating hormone (p = 0.12) and anti-Mullerian hormone (p = 0.16). A trend towards higher total antral follicle count in the high physical activity group vs. the non-active group (34.5 ± 12.9 vs. 28.1 ± 15.2, p = 0.08) and lower Inhibin B (68.1 ± 36.8 vs. 89.4 ± 46.1, p = 0.05). Menarche age correlated with anti-Mullerian hormone (r = 0.387, p = 0.003), as did total antral follicle count (r = 0.368, p = 0.004). IPAQ scores and basal follicle stimulating hormone levels were negatively correlated (r = - 0.292, p = 0.005).
conclusionsAthletic, normo-ovulatory women have ovarian reserves that are at least as good as those of the general population. As this is the first study examining this issue, it could cautiously reassure women engaged in high physical activity regarding ovarian reserve.
