Persistent organochlorine pollutants and menstrual cycle characteristics

Menstrual cycle characteristics in European and Inuit women exposed to persistent organochlorine pollutants.

BACKGROUND Previous inconsistent results suggest that menstrual cycles may be disturbed by exposure to polychlorinated biphenyls (PCBs) and 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (DDE). METHODS Information on menstrual cycle characteristics were obtained by questionnaires, and PCB and DDE were measured in serum samples from a total of 1494 women from Greenland, Swedish fishermen's wiv...

Factors affecting menstrual cycle characteristics.

This 1989-1991 study in California and Utah used daily urinary metabolites of estrogen and progesterone and computer algorithms to assess ovulatory status and day of ovulation. The authors examined the associations of risk factors with menstrual cycle characteristics for 309 working women aged 20-44 years who collected a median of five cycles each of daily urine samples. Linear mixed models wer...

STUDY QUESTION Does moderate alcohol intake affect menstrual cycle characteristics among women in the Danish population? SUMMARY ANSWER Levels of alcohol exposure as seen in this study do not substantially affect the menstrual cycle.

Serum dioxin concentrations and menstrual cycle characteristics.

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a widespread industrial environmental contaminant. Animal studies suggest that TCDD exposure alters the estrus cycle. Twenty years after a 1976 industrial explosion in Seveso, Italy, the authors interviewed female residents to determine whether there was an association between TCDD exposure and current menstrual cycle characteristics. The authors an...
