Which condition is characterized by infertility, lack of menstruation, polycystic ovaries, and hirsutism?

The condition characterized by infertility, lack of menstruation, polycystic ovaries, and hirsutism is polycystic ovarian syndrome (PCOS). This hormonal disorder frequently affects women of reproductive age and is marked by an imbalance in reproductive hormones.

In PCOS, the ovaries often develop numerous small collections of fluid (follicles), which can lead to irregular menstrual cycles and difficulty in conceiving. The lack of menstruation, or amenorrhea, is due to hormonal imbalances that can disrupt the regular ovulatory cycle. Hirsutism, which refers to excessive hair growth in areas where men typically grow hair, is also linked to elevated androgen levels often seen in women with PCOS.

Overall, the combination of these symptoms—infertility, lack of menstruation, presence of polycystic ovaries, and hirsutism—points directly to polycystic ovarian syndrome as the most fitting diagnosis. Other conditions like endometriosis may cause infertility and irregularities in menstruation but do not feature polycystic ovaries as a primary characteristic. Similarly, uterine fibroids and menopause do not fit all the symptoms associated with PCOS.
