Abstract
Here I respond to Akers, Dhar, and Shah's (2016), Stubbs's (2016), Olshansky's (2016), and Kissling's (2016) commentaries on the article (Prior, 2016) in which I expressed concerns about the potential adverse long-term reproductive and bone health effects on normal adolescents’ maturation related to use of combined hormonal contraceptives (CHC) for contraception and/or treatment. Although Akers et al. (2016) take exception, the precautionary principle on which medical/pharmaceutical ethics is based challenges us to show that CHC is officially indicated and effective in randomized, double-blind, placebo-controlled trials with adolescents. Those who support current practices are obligated to provide young patients and their parents with evidence from large, population-based, prospective studies (or meta-analyses of longitudinal data) that adolescents who have used CHC develop the same menstrual cycle/ovulatory function, fertility, and reproductive lifespan and similar bone density and strength as peers who did not use CHC. Without this information there can be neither reproductive justice (Kissing, 2016), nor true choice. Why is this minimal, expected scientific data not available? It is likely that authors of practice guidelines for adolescent CHC contraceptive use and who advocate its “non-contraceptive benefits” have pro-estrogen cultural biases or conflicts of interests due to pharmaceutical industry connections. I agree with Olshansky (2016) that we should listen to adolescents’ concerns and use evidence-based and safe treatments for milder heavy bleeding and cramps. For heterosexual adolescents seeking contraception, we can suggest and explain the use of safer, yet effective, nonhormonal strategies, such as the copper IUD or a barrier plus full-dose vaginal spermicide.

This systematic review and meta-analysis examined the relationship between menstrual cycle phases and the incidence of muscle injuries in female team sport athletes, following PRISMA 2020 and PERSiST guidelines. A comprehensive search was conducted in PubMed, Scopus, and SPORTDiscus from inception to mid-January 2024. Studies were included if they examined female team sport athletes of reproductive age with regular menstrual cycles and compared the occurrence of muscle injuries across at least two menstrual phases. Studies involving hormonal contraceptive use, medications affecting the menstrual cycle or musculoskeletal system, or menstrual dysfunction were excluded. Three studies met the inclusion criteria, involving 318 participants. Meta-analysis yielded a pooled Risk Ratio of 1.18 (95% CI: 0.75 to 1.86, p = 0.46) for injury risk between the luteal and follicular phases, suggesting no statistically significant association. However, the certainty of the cumulative evidence was rated as very low due to methodological limitations, including inconsistent phase classifications and reliance on imprecise methods for identifying menstrual phases. Consequently, no practical or clinical recommendations can be made at this time. Future research employing standardised, physiologically accurate methods for classifying and detecting menstrual cycle phases is necessary to better understand the potential links between hormonal fluctuations and injury risk.

Hormone-based contraception disrupts hormonal balance, creating artificial states of anovulation and threatening women's health. We reviewed its main adverse effects and mechanisms on accelerated ovarian aging, mental health (emotional disruptions, depression, and suicide), sexuality (reduced libido), cardiovascular (brain stroke, myocardial infarction, hypertension, and thrombosis), and oncological (breast, cervical, and endometrial cancers). Other "collateral damage" includes negative effects on communication, scientific mistrust, poor physician-patient relationships, increased patient burden, economic drain on the healthcare system, and environmental pollution. Hormone-sensitive tumors present a dilemma owing to their potential dual effects: preventing some cancers vs. higher risk for others remains controversial, with denial or dismissal as non-relevant adverse effects, information avoidance, and modification of scientific criteria. This lack of clinical assessment poses challenges to women's health and their right to autonomy. Overcoming these challenges requires an anthropological integration of sexuality, as the focus on genital bodily union alone fails to encompass the intimate relational expression of individuals, complete sexual satisfaction, and the intertwined feelings of trust, safety, tenderness, and endorsement of women's femininity.

Since the 1960s, hormonal contraceptives have become the most commonly used method of pregnancy prevention in the United States and the world. Oral contraceptives are used by a large percentage of women, including Christian women. There are known health risks to women demonstrated in research published since Pope Paul VI's prophetic encyclical Humanae vitae in 1968. These risks include venous thrombosis, cardiovascular risks, and an increased risk of cancer. These risks are medically recognized with continued scientific debate on the degree. The risks are significantly increased with preexisting conditions and in certain demographic groups. Discussing known and potential treatment risks is a standard that is both accepted by the medical community and is increasingly expected by patients. This discussion can be accomplished by the mechanism and principle of informed consent. Depending on the circumstances, abstinence or fertility awareness-based methods (FABMs) should be presented to patients. FABMs are licit, safe, and effective methods of pregnancy prevention. Informed consent is the most effective means of providing patients with pertinent information on the significant risks of contraception. This article discusses the use of the informed consent to provide patients with information on the medical and ethical risks of oral contraceptives. FABMs and abstinence are presented as effective, safe, and licit preferences to oral contraceptives. Discussing known and potential treatment risks is accepted by the medical community and expected by patients (shared decision making). The authors discuss the historical context of Pope Paul VI's encyclical Humanae vitae in relationship to the development and rapid adoption of oral contraceptives.
Non-sexually active adolescents are currently treated with combined hormonal contraception (CHC) for common experiences (e.g., cramps, acne) and serious problems (e.g., hypothalamic amenorrhea, heavy menstrual flow) for which it is not indicated, is ineffective, and is likely to cause negative long-term reproductive and bone effects. The importance to a woman's health of adolescent reproductive/bone maturation is described. Evidence is also provided to show the association of CHC use by adolescents with subfertility and inadequate bone growth. Ibuprofen is safer and more effective for cramps and heavy flow; cyclic progesterone builds bone in amenorrhea. In summary, a common, unscientific medical "habit" is compromising long-term reproductive and bone health in adolescents.

Many women use combined hormonal contraceptives (CHC) during adolescence during which they are accruing peak areal bone mineral density (BMD) that relates to lifetime fracture risk. To build BMD requires formation with which CHC-related exogenous oestrogen may interfere. We compared peak BMD accrual in adolescents using and not using CHC. We performed literature searches for prospective published peer-reviewed articles providing 12to 24-month BMD change in adolescent (12to 19-year-old) women using CHC vs CHC-unexposed control women. Meta-analyses used random-effects models to assess BMD change rate at lumbar spine (LS) and other sites in adolescent CHC users vs CHC nonusers. Literature searches yielded 84 publications of which nine were eligible. Adolescent-only data were sought from cohorts with wider age inclusions. The 12-month LS meta-analysis with eight paired comparisons in 1535 adolescents showed a weighted mean BMD difference of -0.02 (95% confidence interval [CI]: -0.05 to 0.00) g/cm(2) in CHC-exposed adolescents (P = 0.04). The 24-month LS meta-analysis with five paired comparisons in 885 adolescents showed a highly significant weighted mean BMD difference of -0.02 (95% CI: -0.03 to -0.01) g/cm(2) in CHC-exposed adolescents (P = 0.0006). Heterogeneities by I(2) were 96% and 85%, respectively. Insufficient data for other bone sites precluded quantitative analysis. Given that adolescent exposure to CHC appears to be increasing, this evidence for potential impairment of peak spinal BMD accrual is of concern and suggests a potential public health problem. Randomized controlled trial data are needed to determine CHC effects on adolescent bone health.
