(a) Circulating plasma prolactin (PRL) of females with oocytes at the RYD phase in relation to oocyte sex and ovulation order. Shown are non-overlapping groups of females that had only one—the first (‘F1- only’) or the last (‘FL-only’) oocyte at the RYD phase at the time of plasma sampling. ‘F2+F3’ were females that had the second and the third oocyte at the RYD stage at the time of sampling. Sample sizes for each follicle and sex are in parentheses. (b) Plasma PRL (circle; n=82 females) and androgen (triangle; n=28) of females that began full incubation with the first egg. Horizontal line shows period of RYD of follicles within a clutch. E1-O indicates the ovulation of the first egg, E2-O is the ovulation of the second egg, laying of the first egg, and the onset of full incubation. PI-1d indicates the first day of the post-egg laying incubation. (c) Circulating plasma androgens (T+5α-DHT) of females with RYD oocytes that became males and females. Asterisk indicates differences between sexes within each group. (d) Relationship between circulating PRL and androgens in females with RYD phase oocytes.
