Women with oligomenorrhea and polycystic ovaries show a high incidence of ovulation failure perhaps linked to insulin resistance and related metabolic features. A number of reports show that the biguanide metformin improves ovarian function. However, in these trials the quality of evidence
BACKGROUND
Primary amenorrhea, oligomenorrhea and secondary amenorrhea are diagnosed commonly during adolescence. Weight aberrations are associated with menstrual disorders. Autoimmune thyroiditis is frequent during adolescence. In this study, the commonest clinical and hormonal characteristics of
Occurrence of reduced BMD among adolescent girls and young women due to certain specific oligomenorrhea or amenorrhea (anorexia nervosa, excessive sport or ballet, etc.) is well known. However the prevalence of osteopenia among 16-18 years old girls with the cycle disorders mentioned above--caused
Nonclassic congenital adrenal hyperplasia (NCAH) is an autosomal-recessive disorder caused by 21-hydroxylase deficiency and manifests as hirsutism and oligomenorrhea due to excess adrenal androgen and progesterone. We report a case of a woman with NCAH who showed continuous high serum progesterone
OBJECTIVE
Oligomenorrhea in active adolescent females of normal weight is presumed to be related to hypoestrogenism secondary to physical activity and decreased fat mass. We hypothesized that active adolescents with oligomenorrhea would have lower estrogen levels than normal controls with similar
OBJECTIVE
There is a paucity of longitudinal endocrine studies of infertile patients with oligomenorrhoea. We have assessed the frequency and quality of spontaneous follicular development and luteal function in patients with oligomenorrhoea and infertility (PCOS), and have related the observed
The aetiology of polycystic ovary syndrome (PCOS) is unknown. It is uniquely characterized by oligomenorrhoea or amenorrhoea associated with normal or high oestrogen levels. This prospective clinical study was designed to examine the possible role of the lack of cyclical exposure to progesterone in
OBJECTIVE
To compare two dosages of oral micronized progesterone (P) and placebo for withdrawal bleeding and side effects.
METHODS
Prospective, randomized, double-blind.
METHODS
Academic institution.
METHODS
Out of 190 screened with oligomenorrhea/amenorrhea, 60 who qualified completed the
This study was to examine indirectly the effect of endogenous progesterone, a known competitor for 5 alpha-reductase, on androgen metabolism in target organs in hirsute women. Serum levels of progesterone, testosterone (T), androstenedione (A), dihydrotestosterone (DHT) and 5 alpha-androstane 3
BACKGROUND
Oligomenorrhea, defined as a menstrual cycle lasting 36 to 90 days, can be a normal condition in the first years after the menarche. When it persists or appears after a period of normal menstrual cycles, an underlying illness must be sought.
OBJECTIVE
To assess ovulation and causes of
High incidences of amenorrhea and oligomenorrhea are often found among late adolescent, college-aged women. We studied menstrual profiles of salivary progesterone in 17 undergraduate women (average age 20.2 years) who were experiencing regular menstrual cycles, and compared the results with similar
Ovarian volumes, measured with ultrasound, and serum estradiol and progesterone concentrations were studied during gonadotropin treatment cycles 1 week after hCG administration in 23 patients, of whom nine had polycystic ovarian syndrome (PCO), eight oligomenorrhea or amenorrhea corresponding to WHO
Two hundred and thirty-five courses of treatment with clomiphene and human chorionic gonadotrophin (HCG) were administered for the induction of ovulation in 75 infertile women (three with primary amenorrhoea, 45 with secondary amenorrhoea and 27 with oligomenorrhoea) of whom 61 had previously been
The effects of epimestrol (5 mg every 6 hours for 5 days) on basal levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (Prl), estradiol, progesterone, and dehydroepiandrosterone sulfate, and on the response to LH-releasing hormone (LH-RH) and thyrotropin-releasing
