Ovarian neoplasms, functional ovarian cysts, and oral contraceptives.

Ovarian neoplasms, functional ovarian cysts, and oral contraceptives.

The incidence of ovarian neoplasms and functional ovarian cysts diagnosed at laparotomy or laparoscopy among the 17,000 women taking part in the Oxford Family Planning Association contraceptive study was investigated. Epithelial cancer of the ovary was only 25% as common among those who had ever taken oral contraceptives as those who had never done so (95% confidence interval 8% to 67%). There ...

Oral Contraceptives and Benign Ovarian Tumors Westhoff et al. Oral Contraceptives and Benign Ovarian Tumors

Whether use of combined oral contraceptives (OC) protects against benign ovarian tumors is unknown. A case-control study of pathologically confirmed benign ovarian tumors was conducted in the New York City area and included cases diagnosed from January 1, 1992, to December 31, 1993, and controls identified by random digit dialing. There were 196 cases with serous adenomas, 176 with teratomas, 3...

Oral contraceptives suppress ovarian hormone production.

Transvaginal sonographic appearance of functional ovarian cysts.

Knowledge of the nature of ovarian lesions is important in order to establish the correct treatment and, especially, to detect ovarian cysts that do not require surgical treatment. With the purpose of demonstrating the utility of transvaginal sonography with colour Doppler of ovarian functional ovarian cysts, 378 ovarian tumours were studied, comparing sonographic diagnosis with pathological fi...

Effect of ovarian hormones and oral contraceptives on tryptophan metabolism

Women using oral contraceptives of the combined oestrogen-progestogen type excrete elevated levels of a number of metabolites of the tryptophan-nicotinic acid ribonucleotide metabolic pathway in urine collected after an oral dose of the amino acid. Increased excretions of Nl-methylnicotinamide reflect an enhanced capacity for the conversion of Ltryptophan to nicotinic acid derivatives, although...
