The Prevalence of Polycystic Ovaries on Ultrasound Scanning in a Population of Randomly Selected Women

No differences existed between women with PCO and normal ovaries with respect to uterine size, body mass index, luteinizing hormone levels, serum hormone binding globulin levels and fertility status, but hirsutism, elevated testosterone levels and irregular menstrual cycles were significantly more frequent amongst women withPCO.

The prevalence of polycystic ovaries in healthy women

It is demonstrated that the prevalence of PCO in healthy women varies with age, being more common among women aged < or =35 years than in those aged > or =36 years, and it remains unclear if these women will later develop full-blown syndrome.

The prevalence of polycystic ovaries in women with infertility.

The prevalence of PCO among ovulatory women with infertility is higher than that in the normal population, suggesting that PCO may, perhaps by virtue of an effect of hyperandrogenaemia, contribute to the causes of subfertility in women with regular menses.

Suppression of Aromatase Activity in Polycystic Ovary Syndrome

PCOS affects a large number of women and is associated with menstrual irregularities in a large proportion of women, thus accounting for approximately one third of women with secondary amenorrhea and approximately 90% of Women with oligomenorrhea.

It was revealed that PCOS is common in rural young women of low socioeconomic class and such women presenting with menstrual irregularities need to be investigated for the presence of other endocrine disorders which may be present with or without PCOS.

Polycystic ovaries and associated clinical and biochemical features among women with infertility in a tertiary hospital in Tanzania.

Polycystic ovaries are common among women with infertility, however are not necessarily associated with polycystic Ovary syndrome, and doctors should investigate their clients for PCOS and offer appropriate treatment.

Polycystic ovarian morphology in normal women does not predict the development of polycystic ovary syndrome.

It is suggested that PCOM in women with regular ovulatory cycles does not commonly predispose the development of PCOS, and changes in ovarian morphology over time are evaluated.

Polycystic Ovaries and Hyperandrogenism in Women Taking Valproate for Epilepsy

This Finland study studied 238 women with epilepsy who were seen regularly at the Outpatient Department of the University Hospital, Oulu, Finland and found that menstrual disturbances were present in 13 of the women receiving valproate alone.



Ovulatory disorders in women with polycystic ovary syndrome.

Of the medical methods of ovulation induction in clomiphene non-responders, two methods have emerged as being highly promising: the first is administration of HMG following suppression of the pituitary by an LH-RH analogue and the second is low-dose FSH.

Prevalence of polycystic ovaries in women with anovulation and idiopathic hirsutism.

It is shown that polycystic ovaries, as defined by pelvic ultrasound, are very common in anovulatory women and are not necessarily associated with hirsutism or a raised serum luteinising hormone concentration.

Responses of serum gonadotrophins to LH-releasing hormone and oestrogens in Japanese women with polycystic ovaries.

It seems likely that lower incidence of markedly enlarged ovaries and virilization in Japanese patients may be caused by the difference in ovarian response to gonadotrophin.

Menstrual Characteristics of 2,343 Women Attending the Shepherd Foundation

Menstrual characteristics of 2,343 women attending the Shepherd Foundation Health Testing Centre have been analyzed utilizing a computer system of data analysis, finding 150 patterns, the 10 most common patterns accounting for 40% of the population; most of the latter patterns included menstrual pain and premenstrual tension.

The polycystic ovary. I. Clinical and histologic features.

It was not possible to predict the results of surgery from clinical findings or urinary steroid studies, but evidence for the occasional coexistence of a hyperadrenal state was strong and illustrates the lack of homogeneity in the clinical material.

Clinical assessment of body hair growth in women.

A method was developed for the semiquantitative assessment of body hair growth, and suitable for use in the study of clinical problems associated with hirsuties in women, and an “hormonal” score obtained by adding the gradings obtained from 9 of the 11 sites is being employed in clinical studies.

The length and variability of the human menstrual cycle.

Variability of menstrual-cycle lengths is highest for women under 25 years of age and declines steadily to reach a minimum for ages 35 to 39, then followed by a slight increase for women aged 40 to 44, according to the Center for Population Research.
