Summary: Polycystic ovaries (PCO) diagnosed by ultrasound have been commonly reported amongst healthy women. The study aimed to determine the prevalence of PCO in a population of women from the community, and to relate it to clinical and endocrinological data. Twelve hundred women chosen randomly from electoral rolls were invited to take part in the study. Two hundred and fifty five women (21%) who met eligibility criteria agreed to participate and 183 women (16%) finally completed the study… 

The prevalence of polycystic ovaries in healthy women

TLDR
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.

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

TLDR
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.

The prevalence of polycystic ovary syndrome in Iranian women based on different diagnostic criteria.

TLDR
The Rotterdam prevalence estimates were double those obtained with the NIH criteria and can be used for international comparisons because it was conducted on a representative sample of females using different criteria for the definition of PCOS.

Endocrine and metabolic changes in women with polycystic ovaries and polycystic ovary syndrome

TLDR
The prevalence of the isolated ultrasonographic finding of polycystic ovaries (PCO) in the Finnish population and among women with a history of gestational diabetes (GDM) and changes in the present carbohydrate metabolism were investigated and the nature of the ovarian streoidogenic response of women with PCOS to exogenously administered human chorionic gonadotrophin, human menotrophins and follicle stimulating hormone was evaluated.

The prevalence of polycystic ovaries in women with infertility.

TLDR
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.

Prevalence of Polycystic Ovary Syndrome and Related Disorders in Mexican Women

TLDR
The prevalence of PCOS in Mexican women is approximately 6.0%, similar to other populations, but lower than 12.8% reported in Mexican-American women.

Prevalence of polycystic ovary morphology in a region of South Italy

TLDR
The prevalence of polycystic ovary morphology (PCOM) in the Campania Region of South Italy was assessed as a result of a large information campaign aimed at disease prevention in the adolescent population based on free visits and diagnostics and results were in agreement with previous studies.

Transvaginal ultrasound appearance of the ovary in infertile women with oligomenorrhea: association with clinical and endocrine profiles

TLDR
A wide spectrum of ultrasonographic ovarian findings can be demonstrated in PCOS, extending from apparently normal to markedly enlarged cystic ovaries, and some women show sonographic signs of PCO without hyperandrogenemia, others are hyper androgenemic without clinical symptoms and without typical sonographic PCOS signs.

Polycystic ovaries and recurrent miscarriage--a reappraisal.

TLDR
Polycystic ovarian morphology is not predictive of pregnancy loss amongst ovulatory women with recurrent miscarriage conceiving spontaneously and the search for a specific endocrine abnormality that can divide women with PCO into those with a good and a poorer prognosis for a future successful pregnancy continues.

Prevalence of polycystic ovaries in women with self-reported symptoms of oligomenorrhoea and/or hirsutism: Northern Finland Birth Cohort 1966 Study.

TLDR
In a general population, women with symptoms of oligomenorrhoea and/or hirsutism more often have PCO than asymptomatic women, implying an increased risk for health.

POLYCYSTIC OVARIES—A COMMON FINDING IN NORMAL WOMEN

Transabdominal versus transvaginal ultrasound in the diagnosis of polycystic ovaries in a population of randomly selected women

TLDR
There was no difference in the prevalence of polycystic ovaries diagnosed by transabdominal or transvaginal ultrasound in the group of randomly selected women, however, almost 20% of the women declined a transvaginals ultrasound examination.

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

TLDR
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.

Which is the Best Test to Detect the Polycystic Ovary?

  • Medicine, Biology

TLDR
Overall, a biochemical ‘screen’ consisting of a luteinizing hormone (LH) level > 10 U/1, testosterone (T) >2.6nmol?/l, sex hormone binding globulin (SHBG) <31nmol/l or a FAI >4.5 was 89% sensitive and 98% specific for PCO, which is comparable with the reliability of ultrasound for detecting the PCO.

HETEROGENEITY OF THE POLYCYSTIC OVARY SYNDROME: CLINICAL, ENDOCRINE AND ULTRASOUND FEATURES IN 556 PATIENTS

TLDR
This paper reports an analysis of the clinical, endocrine and ultrasound data within a population of 556 patients with ultrasound‐diagnosed polycystic ovaries to illustrate the limitations in the use of specific clinical or endocrine criteria as requirements for the diagnosis of the poly Cystic ovary syndrome.

Menstrual Characteristics of 2,343 Women Attending the Shepherd Foundation

TLDR
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.

Oestrogen and androgen states in oligo‐amenorrhoeic women with polycystic ovaries

TLDR
Of the 48 women with polycystic ovaries (PCO), 44 (92%) had a withdrawal bleed following progestogen challenge (indicating oestrogenization) compared with just three (18%) of the 17 with non‐PCO (P < 0.001).

Influence of serum luteinising hormone concentrations on ovulation, conception, and early pregnancy loss in polycystic ovary syndrome.

TLDR
It is indicated that high concentrations of luteinising hormone during the follicular phase in women with polycystic ovaries have a deleterious effect on rates of conception and may be a causal factor in early pregnancy loss.

Uterine size and endometrial thickness and the significance of cystic ovaries in women with pelvic pain due to congestion

TLDR
A group of 55 women with chronic pain due to pelvic congestion measurement by ultrasound revealed they had a larger uterus and thicker endometrium as compared with a group of normal women matched for age, parity and the presence of polycystic ovaries found on ultrasound scanning, which is suggested to be caused by oestrogen.

DIFFERENCES IN CLINICAL AND ENDOCRINE FEATURES BETWEEN OBESE AND NON‐OBESE SUBJECTS WITH POLYCYSTIC OVARY SYNDROME: AN ANALYSIS OF 263 CONSECUTIVE CASES

TLDR
The increased frequency of hirsutism in obese compared with lean women with PCOS is associated with increased bio‐availability of androgens to peripheral tissues and enhanced activity of 5α‐reductase in obese subjects.
