The uterine endometrial biopsy (unless some clue that there may be an endometritis). • Don't need to date endometria (proliferative, secretory etc is enough). • Endometrial The Proliferative Phase. After menstruation, proliferative changes occur during a period of tissue regeneration. The endometrium repairs itself and it becomes Jul 23, 2016 The morphology of the endometrial stromal cells varies dramatically throughout the menstrual cycle. During the proliferative phase, the stromal Using the slides below, examine specimens of uterus in different stages of the menstrual between early and late in either the proliferative or the secretory phases. The thickness of the endometrium (the basal and functional layers Nov 6, 2020 English: Micrograph of proliferative phase endometrium.

During this phase, the proliferative endometrium undergoes cell multiplication and tissue growth.
Diseases associated with infertility manifest a proliferative phase defect that can be recognized clinically. The impact of the endometrial proliferative phase on human embryo implantation remains unclear, but deserves further attention, especially since in luteal phase endometrial biopsies, a transcriptional signature predictive for repeated implantation failure has been associated with reduced cell proliferation, possibly indicating proliferative phase involvement. Pathologists call this phase the proliferative endometrium.

Mitotic figures can be seen. Stroma is dense and compact comprising of small oval to spindle shaped cells having scanty cytoplasm. During the proliferative phase the endometrial glands, stroma and vascular endothelium all proliferate leading to an increased volume of the endometrium. The glands are lined by a stratified columnar epithelium with interspersed ciliated cells.

The deeper endometrium basalis, abutting the myometrium, lacks these physiologic phases and serves to regenerate the endometrium functionalis after each menses. In the proliferative (or follicular) phase both the endometrial glands and stroma proliferate in response to the rising estrogen levels of ovarian follicular origin.

1 doctor answer • 1 doctor weighed in My pathology report final diagnosis are as follows: Endometrium biopsy: blood and weakly proliferative phase endometrium with glandular and stromal breakdown. what does that mean? Menstrual phase (days 0 - 5): Estrogen and progestin levels fall in the absence of implantation of a fertilized egg, resulting in breakdown of endometrial stroma Stratum functionalis is shed; spiral arteries constrict to minimize blood loss. Proliferative phase (days 6 - 14): Stratum functionalis is regenerated by cells from stratum basalis
