She says that her menstrual cycles have been light with irregular breakthrough bleeding for the past three months. She also complains of hair loss and increased the growth of facial and body hair. She had menarche at 11. Vital signs are within normal limits. Her weight is 97.0 kg 213.8 lb and height is 157 cm 5 ft 2 in. Physical examination shows excessive hair growth on the patients face, back, linea alba region, and on the hips. There is also a gray-brown skin discoloration on the posterior neck. An abdominal ultrasound shows multiple peripheral cysts in both ovaries. Which of the following cells played a direct role in the development of this patients excessive hair growth?? A: Ovarian follicular cells, B: Adipocytes, C: Pituitary gonadotropic cells, D: Ovarian theca cells, E: Pituitary lactotrophs,  <response>: This is a clinical vignette describing a patient with signs and symptoms of polycystic ovary syndrome PCOS, including irregular menses, hirsutism, obesity, and polycystic ovaries on ultrasound. The key finding in the question stem is excessive hair growth hirsutism in a distribution suggestive of hyperandrogenism. This narrows down the answer choices to cells that are involved in androgen production. Choice A ovarian follicular cells and E pituitary lactotrophs can be eliminated as they do not play a direct role in androgen production. Choice B adipocytes can also be eliminated - although adipose tissue can contribute to excess androgen levels in PCOS through increased peripheral conversion of androgens, adipocytes do not directly produce androgens.Choice C pituitary gonadotropic cells produce luteinizing hormone LH which stimulates ovarian theca cells, but they do not directly produce androgens themselves. Choice D ovarian theca cells is the correct answer. In PCOS, theca cells in the ovary are stimulated by LH to produce excess androgens like testosterone, contributing to hirsutism and virilization.D: Ovarian theca cells
