Abstract
OBJECTIVE Data regarding the use and effect of hormonal contraceptives on bone mass acquisition during adolescence are contradictory. The present study was designed to evaluate bone metabolism in two groups of healthy adolescents using combined oral contraceptives (COC). METHODS A total of 168 adolescents were recruited from 2014 to 2020 in a non-randomized clinical trial and divided into three groups. The COC1 group used 20 μg Ethinylestradiol (EE)/150 μg Desogestrel and the COC2 group used 30 μg EE/3 mg Drospirenone over a period of two years. These groups were compared to a control group of adolescent non-COC users. The adolescents were submitted to bone densitometry by dual-energy X-ray absorptiometry and measurement of bone biomarkers, bone alkaline phosphatase (BAP), and osteocalcin (OC) at baseline and 24 months after inclusion in the study. The three groups studied were compared at the different time points by ANOVA, followed by Bonferroni's multiple comparison test. RESULTS Incorporation of bone mass was greater in non-users at all sites analyzed (4.85 g in lumbar Bone mineral content (BMC)) when compared to adolescents of the COC1 and COC2 groups, with a respective increase of 2.15 g and loss of 0.43g in lumbar BMC (P = 0.001). When comparing subtotal BMC, the control increased 100.83 g, COC 1 increased 21.46 g, and COC 2 presented a reduction of 1.47 g (P = 0.005). The values of bone markers after 24 months are similar for BAP, being 30.51 U/L (± 11.6) for the control group, 34.95 U/L (± 10.8) for COC1, and 30.29 U/L for COC 2 (± 11.5) (P = 0.377). However, when we analyzed OC, we observed for control, COC 1, and COC 2 groups, respectively, 13.59 ng/mL (± 7.3), 6.44 ng/mL (± 4.6), and 9.48 ng/mL (± 5.9), with P = 0.003. Despite loss to follow-up occurring in the three groups, there were no significant differences between the variables in adolescents at baseline who remained in the study during the 24-month follow-up and those who were excluded or lost to follow-up. CONCLUSION Bone mass acquisition was compromised in healthy adolescents using combined hormonal contraceptives when compared to controls. This negative impact seems to be more pronounced in the group that used contraceptives containing 30 μg EE. CLINICAL TRIAL REGISTRATION http://www.ensaiosclinicos.gov.br, RBR-5h9b3c.

Abstract
INTRODUCTION Turner syndrome (TS) is associated with primary ovarian insufficiency (POI) and most adolescents and young adults (AYA) with TS require treatment with hormone replacement therapy (HRT). International consensus guidelines are unclear on the optimal formulation and dosing for HRT after pubertal induction. This study assessed current HRT practice patterns of endocrinologists and gynecologists in North America. METHODS Email listserv members of the North American Society for Pediatric and Adolescent Gynecology (NASPAG) and the Pediatric Endocrine Society (PES) were invited to complete a 19-question survey to assess HRT treatment preferences for the management of POI after completion of pubertal induction in AYA with TS. Descriptive analysis and multinomial logistic regression to predict factors associated with preferred HRT are presented. RESULTS 155 providers (79% pediatric endocrinology, 17% pediatric gynecology) completed the survey. Although 87% (135) reported confidence in prescribing HRT, only half (51%, 79) were aware of published guidelines. Factors significantly associated with preferred HRT included specialty (p = 0.032) and number of patients with TS seen every 3 months (p = 0.024). Gynecologists were 4 times less likely than endocrinologists to prefer hormonal contraceptives and 4 times more likely to favor transdermal estradiol dose of 100 μg/day as compared to lower doses. CONCLUSION Although most endocrinologists and gynecologists report confidence in prescribing HRT to AYA with TS after pubertal induction, there are clear differences in provider preferences based on specialty and higher volume of patients with TS in their practice. Additional studies on comparative effectiveness of the HRT regimens and evidence-based guidelines are necessary for AYA with TS.

Abstract
A growing number of adolescents in the United States identify as transgender and gender nonbinary, and many will seek medical management of menstruation. In this evidence-based review, we recommend a model of gender-affirming care grounded in the tenants of reproductive justice, emphasizing patient autonomy and the development of holistic management plans centered around the patient's unique goals for affirming their gender identity. We then review strategies for achieving menstruation suppression for transgender and gender nonbinary adolescents, including dosing considerations, menstruation, ovulation, contraceptive effects, and metabolic considerations specific to the adolescent population.

Abstract
Reproductive tract bleeding is an underappreciated health care problem among adolescent and young adult (AYA) females with inherited bleeding disorders (IBDs) comprising von Willebrand disease, platelet disorders, hemophilia carriership, and rare factor deficiencies. IBDs are prevalent in women of all ages and have been detected in about 50% of women with menorrhagia or heavy menstrual bleeding (HMB) and about 20% of women with postpartum hemorrhage (PPH). The clinical spectrum of gynecologic and obstetric bleeding in AYA with IBDs ranges from HMB, ovulation bleeding, and surgical bleeding to miscarriages and life-threatening PPH. Reproductive tract bleeding adversely affects the quality of life of this patient population, in addition to causing substantial morbidity and mortality. Early diagnosis of IBDs offers the opportunity for timely intervention with hormones, hemostatic agents, and prophylaxis with factor concentrates, thereby improving outcomes. This review summarizes the epidemiology, pathophysiology, clinical manifestations, diagnostic approach, management, and prophylaxis for reproductive tract bleeding in AYA with IBDs. This review provides a multidisciplinary approach to the problem, which is critical to improve the outcomes of this patient population.

Abstract
Suppression of menstruation and/or ovarian function in adolescent girls may be desired for a variety of reasons. Numerous medical options exist. The choice of the appropriate modality for an individual patient depends on several factors based on differences in the efficacy of achieving menstrual suppression as well as in their side effect profiles. Adolescence is also a period of bone mass accrual in girls, and several of these modalities may negatively influence peak bone mass. This review focuses on the efficacy of achieving menstrual suppression and the effect on bone health of the various options through an overview of the current literature and also highlights areas in need of further research.

Abstract
Hormonal contraception is prescribed commonly to adolescents for myriad indications from pregnancy prevention to treatment for acne, hirsutism or dysmenorrhea. Although use of these hormones generally has no effect or benefits bone health in mature premenopausal women, the same may not be true for adolescents. The teen years are a critical period for acquiring peak bone strength. Sex hormones, growth hormone, and insulin-like growth factors (IGFs) interact to modulate the changes in bone size, geometry, mineral content, and microarchitecture that determine skeletal strength. Combined oral contraceptives (COCs) and intramuscular depo medroxyprogesterone (DMPA) can compromise the expected gains in adolescence by altering estrogen and IGF concentrations. Use of these medications has been associated with slower accrual of bone mineral density (BMD) and increased fracture risk in some studies. Far less is known about the skeletal effects of the newer long acting reversible contraceptives (LARCs). This review takes a critical look at the gaps in current knowledge of the skeletal effects of COCs, DMPA, and LARCs and underscores the need for additional research.

Abstract
Zusammenfassung
Während der Pubertät stellen sich Mädchen in der Praxis oft mit Fragen bezüglich und dem Wunsch nach einer Verhütung vor. Diese Beratung ist eine besondere Herausforderung, da gerade in der Adoleszenz die zuverlässige Kontrazeption zur Vermeidung ungewollter Schwangerschaften sehr wichtig ist und die Jugendlichen durch Nebenwirkungen der Kontrazeptiva nicht verunsichert werden sollten. Dennoch ist es aus medizinischer Sicht obligat, Kontraindikationen wie beispielsweise ein erhöhtes Thromboserisiko oder Wechselwirkungen mit einer bestehenden Medikation abzuklären, um dann gemeinsam mit der Jugendlichen ein geeignetes Kontrazeptivum auszuwählen. Neben der am häufigsten verwendeten Verhütungsmethode in der Adoleszenz – kombinierte Hormonpräparate, auch ggf. im Langzyklus – sollten die Mädchen umfassend über Barrieremethoden, insbesondere über den zusätzlichen Gebrauch von Kondomen zum Schutz vor Geschlechtskrankheiten, über Notfallkontrazeption und über lang wirksame kontrazeptive Maßnahmen informiert werden.

Abstract
Sexual and reproductive health is an important component of comprehensive health care for youth. This statement provides guidance for selecting and prescribing contraceptives for youth, including commonly prescribed hormonal contraceptives-the pill, patch, ring and injectable progestin-and long-acting reversible contraceptives (LARCs). LARCs, including subdermal implants (which are not available in Canada) and intrauterine contraceptives (IUCs), are substantially more effective during typical use than hormonal contraceptives. This statement endorses LARCs as the first-line option for contraception for Canadian youth, while emphasizing that providers must collaborate with youth to select a contraceptive method that is acceptable, safe, effective and practical for them. Strategies that eliminate obstacles to initiating and continuing contraception are provided.

Abstract
Bone growth, development, and remodeling are modulated by numerous circulating hormones. Throughout the lifespan, the extent to which each of the hormones impacts bone differs. Understanding the independent and combined impact of these hormones on controlling bone remodeling allows for the development of more informed decision making regarding pharmacology, specifically the use of hormonal medication, at all ages. Endocrine control of bone health in women is largely dictated by the growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis and the hypothalamic-pituitary-ovarian (HPO) axis. Growth hormone, secreted from the pituitary gland, stimulates cells in almost every tissue to secrete IGF-1, although the majority of circulating IGF-1 is produced hepatically. Indeed, systemic IGF-1 concentrations have been found to be correlated with bone mineral density (BMD) in both pre- and post-menopausal women and is often used as a marker of bone formation. Sex steroids produced by the ovaries, namely estradiol, mediate bone resorption through binding to estrogen receptors on osteoclasts and osteoblasts. Specifically, by increasing osteoclast apoptosis and decreasing osteoblast apoptosis, adequate estrogen levels prevent excessive bone resorption, which helps to explain the rapid decline in bone mass that occurs with the menopausal decrease in estrogen production. Though there are documented correlations between endogenous estrogen concentrations and GH/IGF-1 dynamics, this relationship changes across the lifespan as sex-steroid dynamics fluctuate and, possibly, as tissue responsiveness to GH stimulation decreases. Aside from the known role of endogenous sex steroids on bone health, the impact of exogenous estrogen administration is of interest, as exogenous formulations further modulate GH and IGF-1 production. However, the effect and extent of GH and IGF-1 modulation seems to be largely dependent on age at administration and route of administration. Specifically, premenopausal women using combined oral contraceptive therapy (COC), post-menopausal women taking oral hormone therapy (HT), and both pre- and post-menopausal women using a transdermal form of estrogen therapy (COC or HT) demonstrate disparate GH/IGF-1 responses to exogenous estrogen. This review serves to summarize what is currently known regarding the influence of exogenous estrogen administration across the lifespan on the GH/IGF-1 axis and implications for bone health.

Abstract
BACKGROUND In recent years, several new oral contraceptives have become available. In some ways, they represent an evolution in terms of individualization and compliance on the part of women. The new formulations make it increasingly possible to prescribe a specific hormonal contraceptive on an individual basis. METHODS A systematic literature search of PubMed was performed using the following combination of terms: 'oral contraceptives', 'estroprogestins' and 'combined oral contraceptive'. Only English-language papers published between January 2000 and July 2014 were included in our analysis. The present review analyzes all aspects of the choice of oral contraceptives in the different phases of a woman's life in detail. RESULTS Regarding the estrogen component, lowering the dose of ethinylestradiol (EE) helped reduce associated side effects. Natural estradiol is now available and represents a valid alternative to EE. And regarding progestins, the dose has changed over time, as well as the endocrine and metabolic characteristics. These are the fruit of much research into improvement of old products (19-nor-progesterone-derived progestins) with androgenic effects and testing of new molecules with improved metabolic neutrality in terms of insulin sensitivity and lipid parameters. New progestins were a genuine turning point because they greatly reduced major side effects, such as water retention, and their anti-androgenic properties made them indicated for all forms of hyperandrogenism associated with acne and mild hirsutism. The associations of estradiol/dienogest and estradiol/nomegestrol acetate are the most suitable contraceptives for women with abundant menstrual bleeding and can increase the number of potential users of hormonal contraception. CONCLUSION Progress in the provision of new oral contraceptives has improved the risk/benefit ratio, by increasing benefits and reducing risks. The present challenge is to tailor contraceptives to individual needs in terms of efficacy and protection of reproductive health.

Abstract
BACKGROUND Low-dose combined oral contraceptives (COCs) can interfere with bone mass acquisition during adolescence. This study aimed to evaluate bone mineral density (BMD) and bone mineral content (BMC) in female adolescents taking a standard low-dose COC (ethinylestradiol 20 μg/desogestrel 150 μg) over a 1-year period and to compare their data with those of healthy adolescents from the same age group not taking COCs. METHODS This was a non-randomized parallel-control study with a 1-year follow-up. Sixty-seven adolescents aged from 12 to 19 years, divided into COC users (n = 41) taking 20 μg ethinylestradiol/150 μg desogestrel and COC non-user controls (n = 26), were evaluated by bone densitometry examinations at baseline and after 12 months. Comparisons between the groups at the study onset were performed using the Mann-Whitney test with the significance level fixed at 5% or p < 0.05. Comparisons between the groups at the study onset and after 12 months were based on variations in the median percentages for bone mass variables. RESULTS The COC users presented with low bone mass acquisition in the lumbar spine, and had BMD and BMC median variations of 2.07% and +1.57%, respectively, between the measurements at baseline and 12 months. The control group had median variations of +12.16% and +16.84% for BMD and BMC, respectively, over the same period. The total body BMD and BMC showed similar evolutions during the study in both groups. Statistical significance (p < 0.05) was seen for the BMC percentage variation between COC users and non-users. CONCLUSIONS Use of a low-dose COC (ethinylestradiol 20 μg/desogestrel 150 μg) was associated with lower bone mass acquisition in adolescents during the study period.

Abstract
OBJECTIVE Combined oral contraceptives (COCs) are increasingly used by adolescents. The aim of this review is to investigate the evidence regarding COCs' influence on weight, height and bone mineral density (BMD) in girls younger than 18 years. METHOD Systematic literature search using PubMed/Medline and Scopus (January 1990-February 2012) on COCs for girls under 18 years of age and the possible influence on body parameters. MeSH terms: Oral contraception; Adolescent; Weight; Body composition; Height; Bone mineral density. RESULTS There is no evidence that COCs induce weight gain in girls younger than 18 years. Obese girls are not at higher risk of gaining weight. COCs do not cause changes in body fat and lean mass beyond the changes caused by natural development. Moreover, growth and stature are unaffected. Few studies indicate that COCs have a negative impact on BMD, but the evidence is presently too limited for definite conclusions. CONCLUSION Studies in young users are few. Presently, there are no indications of a negative impact of COCs on weight, body composition or height. Lesser increases in BMD cannot be excluded. As the demand for COCs is increasing among the youngest girls, there is a need for prospective studies addressing this issue.

Abstract
BACKGROUND Steroid hormonal contraceptives are highly effective and widely used. Most studies have shown a negative effect of combined oral contraceptives (COCs) on the bone mineral density (BMD) of adolescents. The study was conducted to compare BMD among users of ethinylestradiol/desogestrel, users of ethinylestradiol/cyproterone acetate and nonhormonal control subjects in women aged 16-18 years. STUDY DESIGN The study included 450 women 16-18 years of age. One hundred fifty women were using ethinylestradiol/desogestrel, 150 women were using ethinylestradiol/cyproterone acetate, and 150 women were using nonhormonal contraception as control subjects. BMD ofthe lumbar spine and femoral neck was obtained using dual-energy X-ray absorptiometry, and mean BMD changes in COCs users and nonusers were compared. RESULTS At 24 months of treatment, lumbar spine and femoral neck mean BMD values in women (n=127) who used ethinylestradiol/desogestrel were slightly lower compared with baseline, but these effects did not reach statistical significance (p=.837 and p=.630, respectively). The mean lumbar spine and femoral neck BMD values in women (n=134) who used ethinylestradiol/cyproterone acetate were slightly higher compared with baseline, but there was no statistical significance (p=.789 and p=.756, respectively). The increases in mean percent change in lumbar spine and femoral neck BMD in the ethinylestradiol/cyproterone acetate group were less than those in the control group (1.88% vs. 0.30% and 0.98% vs. 0.49%, respectively). There were no significant differences in mean BMD of the lumbar spine and femoral neck between the users of ethinylestradiol/desogestrel or ethinylestradiol/cyproterone acetate and nonusers (p>.05). CONCLUSION Our study indicates that 2 years of COCs therapy had no significant effect on bone density in adolescents, but it remains unknown whether therapy longer than 2 years has a significant adverse effect on the attainment of peak bone mass.

Abstract
Adolescence is a critical period for girls with type 1 diabetes mellitus (T1D). Reproductive issues, such as menstrual abnormalities, risk of an unplanned pregnancy, and contraception, should be addressed during this phase of life. This paper reviews several reproductive issues that are important in the care of adolescents, including pubertal development, menstrual abnormalities, ovulatory function, reproductive problems, the effects of hyperglycemia, contraception, and treatment of an unplanned pregnancy. A review of the literature was conducted. A MEDLINE search January 1966 to March 2011 was performed using the following MESH terms: puberty, menarche, ovary, polycystic ovary syndrome, menstruation, contraception, contraception-barrier, contraceptives-oral-hormonal, sex education, family planning services, and pregnancy in adolescence. This literature search was cross-referenced with an additional search on diabetes mellitus-type 1, diabetes complications, and pregnancy in diabetes. All published studies were searched regardless of the language of origin. Bibliographies were reviewed to extract additional relevant sources.

Abstract
Sex hormones play a key role in bone homeostasis, and oral contraceptive (OC) use may affect bone mass in women. However, the nature of the association between OC use and bone remains controversial. This paper critically reviews studies on OC use and bone published between January 2009 and August 2010. Studies of OC use and bone mass mainly focus on adolescents or young adults and showed mixed results. Weak evidence suggests that OC use has no effect or a beneficial effect on bone mass, except in women commencing OCs shortly after menarche, and a consistently negative effect on bone turnover markers. A limited number of studies have examined the effect of ultra-low-dose OC (20 μg ethinyl estradiol) on bone mass in adolescents or young adults, and present conflicting results. The lack of randomized trials indicates that further high-quality prospective studies are required to investigate the effect of OC use on bone mass, particularly the optimal dose and timing of initiation of OC use in adolescents requiring contraception.
