OBJECTIVE To assess the risk of borderline ovarian cancer among infertile women treated with fertility drugs. DESIGN Case-control study. SETTING Nationwide data obtained from public registers and postal questionnaires. PATIENT(S) All Danish women <60 years old with borderline ovarian cancer during the period 1989-1994 and randomly selected population controls. The analysis included 231 ca...

This paper deals with study of the characteristics of clinical course of benign ovarian tumor formations in women of reproductive age, depending on the fertility and the choice of treatment strategy. Functional ovarian cysts in 60,45 % of cases were diagnosed in parous patients, in 39,55 % in nulliparous women, in 5,22 % in women with infertility. Corpus luteum cysts in 36,96 % of cases occured...

Early studies of breast cancer raised substantial concern regarding risk associated with induced abortion and miscarriage. Literature reviews suggest that study findings depend heavily on the comparison group and that the use of parous women as a reference group for nulliparous women may artificially inflate risk. To examine the individual effects of induced abortion and miscarriage on breast c...

MATERNITY is commonly believed to be an important contributory cause of increased weight in women. Sheldon (1949) provided circumstantial evidence from the histories of obese parous women, and further support was given by the conclusion of Thomson and Hytten (1961) that about 30% of the average weight gained during pregnancy is due to an increase of body fat. Yet Thomson and Billewicz (1965) sh...

The morphology of the female Cyrtobagous salviniae Calder and Sands reproductive system is similar to other weevil species being meroistic and telotrophic. The reproductive system is composed of 2 ovaries each containing 2 ovarioles where the follicles mature. A physiological age grading system was developed where the continuum of ovarium development was divided into 2 nulliparous and 3 parous ...
