Figure 4. Physiological response of the ovary to hormonal stimulation.

Figure 4

(a–e) Stereomicroscope images and perfusion maps of the mouse ovary undergoing hormonal changes upon injection of pregnant mare’s serum gonadotropin (PMSG; injected at day 2) and human chorionic gonadotropin (hCG; injected 48 h after PMSG, at day 4). Asterix indicates the same ovarian follicle at different time points; arrow denotes the same blood vessel. Calibration bars denote color-coded intensity range (0–255) which corresponds to blood flow map of each time point. (f) Hematoxylin and eosin-stained histological section of the ovary showing corpora lutei formed after ovulation. Asterix denote corpora lutea. a-e were imaged in-vivo in the imaging window.
