Birth Control Pill Risks

Recent oral contraceptive use and adverse birth outcomes. Chen XK, Wen SW, Sun LM, Yang Q, Walker MC, Krewski D. Eur J Obstet Gynecol Reprod Biol. 2009 May;144(1):40-3. Epub 2009 Feb 23.

OBJECTIVE: To examine the possible association between oral contraceptive use and adverse birth outcomes.

STUDY DESIGN: We conducted a population-based cohort study of pregnant women who used oral contraceptives within 3 months before their last menstrual period. Subjects were divided into three groups, according to the interval (0-30, 31-60, and 61-90 days) between the dispensing date and their last menstrual period. For each exposed subject, 4 subjects without exposure to oral contraceptives were individually matched by infant's year of birth and plurality and by mother's age and parity.

RESULTS: Oral contraceptive use within 30 days prior to the last menstrual period was associated with increased risks of very low birth weight (OR: 3.24, 95% CI: 1.18, 8.92), low birth weight (OR: 1.93, 95% CI: 1.17, 3.20), and preterm birth (OR: 1.61, 95% CI: 1.01, 2.55); however, oral contraceptive use 31-90 days prior to the last menstrual period did not increase the risk of low birth weight or preterm birth.

CONCLUSION: Our results indicate the use of oral contraceptives near the time of conception may be associated with an increased risk of low birth weight and preterm birth.

Birth control pill may lead to a permanent reduction in libido. BOSTON, May 26, 2005 (LifeSiteNews.com)The researchers studied the use of the pill on 124 women at a sexual dysfunction clinic. Those who continued taking the Pill had four times the normal SHBG levels of women who had never taken it. Those women in the study who stopped taking the pill at the beginning of the study still had twice the normal level of SHBG after a year. The team's research leader, Dr Claudia Panzer, an endocrinologist at the Boston University Medical Center, said the study indicated that the loss of libido might not be reversible.

birth control pill

ESTROGEN LINKED TO CANCER: The National Toxicology Program advisory committee voted 8-1 that steroidal estrogen -- a type used in post-menopausal treatments and birth control pills -- should be placed on the nation's list of cancer-causing substances. The committee found an association with endometrial cancer, and to a lesser extent, breast cancer. (Reading: "Panel Puts Estrogen on Cancer List," New York Times,12/15/00)

Condom Risks

Abstract

A survey has been conducted during the past decade (starting in 1980) of reported new cases of women with breast cancer, in order to assess the interim evidence of the natural experiment of the effect of increased use of condoms on the risk of breast cancer in the US. Age-adjusted incidence rates of breast cancer (to the world standard population) per 100,000 population, and trends of changes, in percentages, were used. Prior to the 1980s, breast cancer incidence was in decline in seven out of 13 centres in the country. Following the recommendations to use condoms in 'safer sex' campaigns, increases of breast cancer incidence were recorded during the 1980s, as a reflection of a global phenomenon. Between the 5 year periods of 1978-82 and 1983-87, the population of the nine Surveillance, Epidemiology and End Results programme (SEER) centres (about 10% of the American population), increased by 2.9%, the number of breast cancer cases increased by 25.0%; the average annual breast cancer crude incidence rose by 21.5% (from 100.8 to 122.5 per 100,000). The increase in the average annual number of breast cancer cases during the period 1983-87 (the period of increased condom usage) was 4.5 times greater than that during the preceding period, 1978-82. During the 1980s, breast cancer trends rose significantly in the US among White women (P < 0.00001) and other ethnic groups (P < 0.005). The difference between the expected, 21%, and observed, 79%, probability of adverse effects occurring in the natural experimental trial was statistically significant (P = 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS)
