A–B AARS2 regulates estrous cyclicity. Representative estrous cyclicity of C57, AARS2 GOE, Aars2 GKO, and AARS2 ZOE mice during 15 consecutive days since postnatal 8 weeks (A) and the cycle phase times (n = 16 for AARS2 GOE and 14 for Aars2 GKO and AARS2 ZOE) represented as mean ± SEM (B). C AARS2 affects the litter size. The cumulative number of pups in C57, AARS2 GOE, Aars2 GKO, and AARS2 ZOE was analyzed (n = 6). D–E Levels of FSH (D) and E2 (E) in adult AARS2 GOE and WT mice (16–20 weeks old, n = 14) were measured. F AARS2 does not affect oocyte number. The number of oocytes in C57, AARS2 GOE, and Aars2 GKO mice (n = 6, one ovary from each mouse) was measured at PD1. See also Fig. S2. G AARS2 affects ovarian follicle number. The ovarian follicles in AARS2 GOE, Aars2 GKO, and C57 mice were quantified (n = 6) at PD5, 8, and PD3-, 5-, and 7-weeks. Numbers of primordial (Pri), primary (Pr), type 4 (T4), type 5 (T5), type 6 (T6), and type 7 (T7) follicles were counted (mean ± SEM). See also Fig. S2.
