In dominant follicles, however, no IGF-I mRNA has been detected either in thecal or in granulosa cells, and IGF-II expression is restricted to granulosa cells only. my life as inukai\u0027s dog streaming

"網頁Thecal cells lack aromatase, but are able to produce the androgen precursor, which is then converted to estrogen (specifically, estradiol) by the granulosa cells. The dominant follicle continues to enlarge and secrete higher and higher levels of estrogen. " - Thecal cells secrete

網頁The regularity of the menstrual cycle in women of reproductive age can be affected by anatomical defects of the uterus or vagina, or by functional or structural defects in the hypothalamic–pituitary–ovarian axis that affect hormonal secretions. 網頁Interstitial cells are formed from thecal cells that persist following follicular atresia and they remain responsive to LH stimulation and produce androstenedione. It is common to see …

網頁Function. A granulosa cell or follicular cell is a somatic cell of the sex cord that is closely associated with the developing female gamete (called an oocyte or egg) in the ovary of mammals (Pic. 1). In female, theca and granulosa cells (Pic. 2) within the ovary mainly produce estrogen (a group of hormones that primarily influence the female ...
