What would you find in a blood test? Group of answer choices Absence of only progesterone. Absence of progesterone and estradiol only. Absence of progesterone, androgens, and estradiol. Absence of androgens and estradiol. Absence of only estradiol.

A 16-year-old girl comes into your office to determine the reason why she hasn't started menstruating yet. Further tests reveal that she lacks internal female sex organs but she does have abdominal testes, vas deferens, and a prostate gland. Based on this information, what can you tell me about your patient? - She has an excess of androgen receptors. - She is a genetic male (XY). - None of these answers is appropriate. - She has persistent MĂĽllerian syndrome.

Ovarian follicles contain various stages of development: oocytes, progestin-secreting granulosa cells, and primordial follicles. When the corpus luteum (CL) degenerates, circulating levels of progesterone and estrogen decrease rapidly. FSH and LH secretion start to decrease due to the inhibitory effects of the gonadal steroids being withdrawn. Portions of the endometrium slough off. The corpus luteum can persist beyond its two-week life span only if it is stimulated by the hormone: LH. The reproductive system produces gametes, stores and transports gametes, and nourishes gametes. The muscular layer of the uterus is the myometrium. The surge of LH that occurs during the middle of the ovarian cycle triggers ovulation. The principle hormone released by the corpus luteum, also known as the "hormone of pregnancy," is progesterone. The developing follicular cells secrete estrogen, FSH, and LH. The part of the female reproductive system that is shed during menstruation is the stratum functionalis of the endometrium.
