Effect of cyclofenil on hormonal dynamics, follicular development and cervical mucus in normal and oligomenorrhoeic women.

Cyclofenil is a triphenylethylene derivative, similar in structure to clomiphene citrate, which is used to induce ovulation in anovulatory women. The effects of cyclofenil on a group of 10 normal cyclic and 10 oligomenorrhoeic subjects were examined in a double blind controlled cross-over study. Both groups of women were administered either cyclofenil or, following a washout cycle, a placebo in two treatment cycles. Urinary oestrone and pregnanediol excretion were measured daily and ultrasound scans performed to assess follicular development. Frequent sampling of blood was performed on day 6 to study luteinizing hormone (LH) and follicle stimulating hormone (FSH) pulsatile release. Cervical mucus changes and sperm-cervical mucus interaction were studied after identification of the LH peak. There were no significant differences between cyclofenil and placebo cycles in the following: ovulation rates, daily urinary oestrone and pregnanediol excretion, the number or size of developing follicles, LH pulsatility (parameters studied: number of peaks, pulse interval, pulse amplitude, pulse area and mean nadir LH), mean FSH level on day 6, cervical mucus and sperm-cervical mucus interaction. In view of our inability to demonstrate an effect on any parameter of endocrine function in normal and oligomenorrhoeic women, these results throw doubt on the therapeutic value of cyclofenil in its present dosage and formulation.

High dietary fiber and low saturated fat intake among oligomenorrheic undergraduates.

Numerous functional risk factors are associated with the occurrence of secondary amenorrhea in young women. Less is known regarding factors associated with the more prevalent problem of oligomenorrhea. We have evaluated nutrient intake, body composition, perceived psychological stress, 24-hour urinary cortisol, and urinary C peptide (UCP) in 35 eumenorrheic, 11 mildly oligomenorrheic, and 10 oligomenorrheic nonathletic undergraduate women. Nutrient intake was evaluated by a validated food frequency questionnaire. Oligomenorrheic women were found to consume significantly more dietary fiber, crude fiber, and polyunsaturated fat, and significantly less saturated fat than their eumenorrheic classmates. Oligomenorrheic women had significantly lower 24-hour UCP excretion than mildly oligomenorrheic women. The groups did not differ in any aspect of body composition, body weight, age of menarche, perceived psychological stress, or urinary cortisol excretion. The data suggest that higher intake of fiber and lower intake of saturated fat may be associated with oligomenorrhea among otherwise healthy undergraduate nonathletic women.

Oligomenorrhea in adolescent girls.

Forty-two patients ages 15 to 20 years (average 17.3 years) were evaluated for oligomenorrhea. Group I consisted of 19 patients with evidence of androgen excess (hirsutism, clitoromegaly, acne); and Group II included 23 patients without evidence of androgen excess. Sixteen of the 19 patients in Group I had elevated serum LH and normal FSH values. Serum total testosterone concentration was elevated in 12 patients and free T was elevated in one additional patient. In nine patients urinary 17KS excretion was elevated and dexamethasone suppressible. For the purpose of treatment, patients in Group I were divided into three subgroups: IA, polycystic ovary syndrome--12 patients; IB, adrenal block--two patients; IC, combined adrenal and ovarian hyperandrogenism--five patients. Among the 23 Group II patients, four had persistently elevated serum LH and normal FSH values, suggesting PCO; three had menopausal levels of LA and FSH; one had hyperprolactinemia and a depressed floor of the pituitary sella; and the remaining 15 patients had low to normal serum levels of LH and FSH, consistent with hypothalamic suppression. Guidelines for the diagnosis and treatment of adolescents with oligomenorrhea are discussed on the basis of these findings.
