TL;DR
The Assamese monkey can serve as an appropriate model for the study of primate reproductive physiology and the concentrations and patterns of these hormones were similar to those reported for other species of macaques.
Abstract
The endocrine characteristics of the menstrual cycle were determined in 16 Assamese monkeys (Macaca assamensis). Average cycle length was 32 ± 2 (± SEM) days which was divided into a 16 ± 1 day follicular phase and a 16 ± 1 day luteal phase. LH and FSH concentrations were fairly constant throughout the cycle except at midcycle when both gonadotropins surged. At this time LH concentrations increased from 4 ± 2 to 17 ± 4 μg/ml (mean ± SEM) and FSH from 3 ± 1 to 9 ± 1 μg/ml. Estrogens also increased at midcydle from 275 ± 75 to 432 ± 89 pg/ml. Progesterone rose from less than 0.5 ng/ml during the follicular phase to between 2 and 4 ng/ml during the luteal phase. Although there was variation between animals, the concentrations and patterns of these hormones were similar to those reported for other species of macaques. These results suggest that the Assamese monkey can serve as an appropriate model for the study of primate reproductive physiology.

Circulating levels of LH, FSH, estradiol and progesterone were measured by radioimmunoassays in daily serum samples throughout the menstrual cycle of seven adult cynomolgus monkeys, showing a composite pattern that strongly resembles that reported for rhesus monkeys.

The good agreement between the estimates of LH by radioimmunoassay and by bioassay for a crude pituitary extract suggested that other pituitaries did not influence the measurement of LH, and exogenous LH could be completely and quantitatively recovered when added to serum.

The results indicate that food intake fluctuated with changes in hormonal secretion, and a significant decrease in the amount of food consumed correlated well with the midcycle estrogen and gonadotropin surges.

It is concluded that ovulation in this species occurs within 24 hr after the LH peak and that the patterns of circulating LH and progesterone during the menstrual cycle of the rhesus monkey closely resemble those in the human female.
