Abstract
Many female military service members choose to use hormonal contraception to prevent pregnancy and/or to control or suppress menses. Hormonal contraception, which comes in many different forms based on dose, estrogen/progestin type, and route of administration (oral, vaginal, transdermal, implant, intrauterine device, injectable), may cause side effects, some of which can influence military medical readiness, or the health status necessary to perform assigned missions. This expert review summarizes the evidence around common military-relevant side effects of hormonal contraception that could impact readiness, including effects on weight and body composition, bone health, psychological health, and physical performance, and serves as a tool for uniformed and civilian clinicians counseling female service members about hormonal contraception. Current evidence suggests some hormonal contraception can lead to weight and fat gain, may modulate susceptibility to mood or mental health disorders, and could impact bone mineral density and stress fracture risk; more research is needed on physical performance effects. Clinicians must be familiar with readiness considerations of each type of hormonal contraception to provide comprehensive patient education and allow for optimal shared decision-making about hormonal contraception use among female Service members. Considering the relative lack of data on the effects of nonoral hormonal contraception routes on readiness outcomes and the growing interest in long-acting reversible contraceptives among female service members, future research should continue to investigate effects of all hormonal contraception methods available to service members.

Abstract
The 2024 U.S. Medical Eligibility Criteria for Contraceptive Use (U.S. MEC) comprises recommendations for the use of specific contraceptive methods by persons who have certain characteristics or medical conditions. These recommendations for health care providers were updated by CDC after review of the scientific evidence and a meeting with national experts in Atlanta, Georgia, during January 25-27, 2023. The information in this report replaces the 2016 U.S. MEC (CDC. U.S. Medical Eligibility Criteria for Contraceptive Use, 2016. MMWR 2016:65[No. RR-3]:1-103). Notable updates include 1) the addition of recommendations for persons with chronic kidney disease; 2) revisions to the recommendations for persons with certain characteristics or medical conditions (i.e., breastfeeding, postpartum, postabortion, obesity, surgery, deep venous thrombosis or pulmonary embolism with or without anticoagulant therapy, thrombophilia, superficial venous thrombosis, valvular heart disease, peripartum cardiomyopathy, systemic lupus erythematosus, high risk for HIV infection, cirrhosis, liver tumor, sickle cell disease, solid organ transplantation, and drug interactions with antiretrovirals used for prevention or treatment of HIV infection); and 3) inclusion of new contraceptive methods, including new doses or formulations of combined oral contraceptives, contraceptive patches, vaginal rings, progestin-only pills, levonorgestrel intrauterine devices, and vaginal pH modulator. The recommendations in this report are intended to serve as a source of evidence-based clinical practice guidance for health care providers. The goals of these recommendations are to remove unnecessary medical barriers to accessing and using contraception and to support the provision of person-centered contraceptive counseling and services in a noncoercive manner. Health care providers should always consider the individual clinical circumstances of each person seeking contraceptive services. This report is not intended to be a substitute for professional medical advice for individual patients; when needed, patients should seek advice from their health care providers about contraceptive use.

Abstract
PURPOSE Oral contraceptives (OCs) are commonly used by female athletes raising concerns regarding the possible adverse effects of OCs on physical performance, musculoskeletal injuries, and bone density. We aimed to review all current studies on the physiological effects of OCs in physically active women. MATERIALS AND METHODS A review of literature in electronic search in PubMed and Google Scholar databases from December 2002 to December 2022 using relevant keywords. The reference lists of the articles found eligible were also reviewed. RESULTS Out of 344 articles in the initial database, 54 clinical studies were eligible for inclusion in our literature review. OCs are used by about two-thirds of female athletes. Current research suggests that OCs' effects on endurance performance and muscle strength are mostly reassuring. OCs do not seem to have a major negative impact on bone health or sports injuries. In fact, new data suggests that they may even significantly reduce the risk of anterior cruciate ligament (ACL) injury. CONCLUSIONS OCs can be safely used by young female athletes, who may also benefit from better menstrual cycle control. OCs offer newly realised protection from ACL injuries. The use of OCs must be carefully individualised according to their preferences, expectations, and experience.

Abstract
Peak bone mass acquisition during adolescence is an important determinant of adult bone health. Knowledge about the effects of different contraceptives on peak bone mass acquisition could influence choice of method recommended. This review summarizes normal bone acquisition during adolescence, discusses methods of assessing bone health in this age group, and reviews the effects of different contraceptive options on bone health, both in adults and in adolescents. Based on the evidence, long-acting reversible contraceptives do not appear to affect peak bone mass acquisition or future fracture risk and remain the first-line contraceptive choice for adolescents. Oral contraceptives with doses of ethinyl estradiol greater than 30 μg should be used in preference to lower-dose preparations, and the adverse effects of depo medroxyprogesterone acetate (DMPA) on bone health are reversible on discontinuation of the medication. Concerns about bone health should not prevent use of DMPA in an adolescent who prefers this method.

Abstract
Unintended teen pregnancy continues to be a problem in the United States which has the highest rate of adolescent pregnancy among developed nations. Long-acting reversible contraception (LARC) has much higher continuation rates compared with moderately effective reversible contraception; however, moderately effective reversible contraception is more commonly used by adolescents. The American Academy of Pediatrics and the American College of Obstetricians and Gynecologists recommend LARC as first-line contraception for adolescents. Clinicians providing contraception to adolescents should be knowledgeable of LARC indications, side effects, initiation guidelines, management of adverse reactions, and adolescent specific issues regarding LARC counseling, initiation, and continuation.

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
PURPOSE To discuss common myths and misconceptions about long-acting reversible contraception (LARC) among patients and health care providers. METHODS We address some of these common myths in an effort to provide clinicians with accurate information to discuss options with patients, parents, and referring providers. The list of myths was created through an informal survey of an online listserv of 200 family planning experts and from the experiences of the authors. RESULTS When presented with information about LARC, adolescents are more likely to request LARC and are satisfied with LARC. Clinicians have an important role in counseling about and providing LARC to their adolescent patients as well as supporting them in managing associated side effects. CONCLUSIONS This review article can be used as a resource for contraceptive counseling visits and for the continuing education of health professionals providing adolescent reproductive health care.

Abstract
Norgestrel, a synthetic progestin chemically derived from 19-nortestosterone, is six times more potent than progesterone, with variable binding affinity to various steroid receptors. The levonorgestrel-releasing intrauterine system (LNG IUS) provides a long-acting, highly effective, and reversible form of contraception, with a pearl index of 0.18 per 100 women-years. The locally released hormone leads to endometrial concentrations that are 200-800 times those found after daily oral use and a plasma level that is lower than that with other forms of levonorgestrel-containing contraception. The contraceptive effect of the LNG IUS is achieved mainly through its local suppressive effect on the endometrium, leading to endometrial thinning, glandular atrophy, and stromal decidualization without affecting ovulation. The LNG IUS is generally well tolerated. The main side effects are related to its androgenic activity, which is usually mild and transient, resolving after the first few months. Menstrual abnormalities are also common but well tolerated, and even become desirable (eg, amenorrhea, hypomenorrhea, and oligomenorrhea) with proper counseling of the patient during the choice of the method of contraception. The satisfaction rates after 3 years of insertion are high, reaching between 77% and 94%. The local effect of the LNG IUS on the endometrium and low rates of systemic adverse effects have led to its use in other conditions rather than contraception, as for the treatment of endometrial hyperplasia, benign menorrhagia, endometriosis, adenomyosis, and uterine fibroids.

Abstract
Abstract
Objectives
This article is aimed to review the novel actions of progesterone, which otherwise is considered as a female reproductive hormone. The article focuses on its important physiological actions in males too and gives an overview of its novel perspectives in disorders of central and peripheral nervous system.
Key findings
Progesterone may have a potential benefit in treatment of traumatic brain injury, various neurological disorders and male related diseases like benign prostatic hypertrophy (BPH), prostate cancer and osteoporosis. Norethisterone (NETA), a progesterone derivative, decreases bone mineral loss in male castrated mice suggesting its role in osteoporosis. In the future, progesterone may find use as a male contraceptive too, but still needs confirmatory trials for safety, tolerability and acceptability. Megestrol acetate, a progesterone derivative is preferred in prostatic cancer. Further, it may find utility in nicotine addiction, traumatic brain injury (recently entered Phase III trial) and Alzheimer's disease, diabetic neuropathy and crush injuries. Studies also suggest role of progesterone in stroke, for which further clinical trials are needed. The non genomic actions of progesterone may be in part responsible for these novel actions.
Summary
Although progesterone has shown promising role in various non-hormonal benefits, further clinical studies are needed to prove its usefulness in conditions like stroke, traumatic brain injury, neuropathy and crush injury. In male related illnesses like BPH and prostatic Ca, it may prove a boon in near future. New era of hormonal male contraception may be initiated by use of progesterone along with testosterone.

Abstract
The contraceptive profile of the levonorgestrel-releasing intrauterine system (LNG-IUS; Mirena®) is well established, with efficacy similar to that achieved with sterilization and rapid return to fertility after discontinuation of use. The LNG-IUS is typically associated with transient menstrual disturbance during the first few months of use, but this usually settles with continued use, with a concomitant decrease in menstrual blood loss. Overall, the safety profile of the LNG-IUS has been well established across a wide population of women, and the available data do not suggest that the LNG-IUS adversely affects bone health or increase the risk of adverse cardiovascular events or breast and uterine cancers. This article reviews the literature to provide updated information on the risks and benefits associated with the LNG-IUS, particularly focusing on its use in contraception.

Abstract
Combination hormonal contraception and progestin-only contraception (including depot medroxyprogesterone acetate [DMPA]) are effective and convenient forms of reversible contraception that millions of women use worldwide. In recent years, observations of reduced bone mineral density in current users of these methods have led to concerns that this hormone-induced bone loss might translate into long-term increased fracture risk. Special focus has been placed on adolescent users who have not yet attained their peak bone mass as well as perimenopausal users. In 2004, the FDA added a black box warning to DMPA package labeling warning of the risk of significant bone loss and cautioning against long-term use (> 2 years). This article reviews evidence on the use of hormonal contraception and its effect on bone density in adolescent, premenopausal, and perimenopausal populations. Recommendations from reproductive healthcare organizations are reviewed and clinical recommendations are provided.

Abstract
Female-controlled contraception/HIV prevention is critical to address health issues associated with gender inequality. Therefore, a contraceptive which can be administered in tandem with a microbicide to inhibit sexually transmitted infections, is desirable. Uterine leukemia inhibitory factor (LIF) is obligatory for blastocyst implantation in mice and associated with infertility in women. We aimed to determine whether a PEGylated LIF inhibitor (PEGLA) was an effective contraceptive following vaginal delivery and to identify non-uterine targets of PEGLA in mice. Vaginally-applied 125I-PEGLA accumulated in blood more slowly (30 min vs 10 min) and showed reduced tissue and blood retention (24 h vs 96 h) compared to intraperitoneal injection in mice. Vaginally-applied PEGLA blocked implantation. PEGLA administered by intraperitoneal injection inhibited bone remodelling whereas vaginally-applied PEGLA had no effect on bone. Further, PEGLA had no effect in an animal model of multiple sclerosis, experimental auto-immune encephalomyelitis, suggesting PEGLA cannot target the central nervous system. Vaginally-administered PEGLA is a promising non-hormonal contraceptive, one which could be delivered alone, or in tandem with a microbicide. Vaginal application reduced the total dose of PEGLA required to block implantation and eliminated the systemic effect on bone, showing the vagina is a promising site of administration for larger drugs which target organs within the reproductive tract.

BACKGROUND Progestogen therapy has been found to be useful in controlling endometriosis. For patients after conservative surgery, long-term medical maintenance therapy should be sought to prevent recurrence and control symptoms. Levonorgestrel-releasing intrauterine system (LNG-IUS) may be a useful form of prolonged progestogen therapy for endometriosis. AIMS To evaluate and compare the efficacy and safety of LNG-IUS to depot medroxyprogesterone acetate (MPA) for patients with moderate or severe endometriosis following conservative surgery, in terms of symptoms control, recurrence prevention and patients' acceptance. METHODS A total of 30 patients after conservative surgery for endometriosis underwent randomisation. Of these patients, 15 received LNG-IUS and 15 had three-monthly depot MPA for three years. Their symptom control, recurrence, compliance and change in bone mineral density (BMD) were compared. The data were analysed using student's t-test and chi-square test. RESULTS Symptoms and recurrence were controlled by both therapies. The compliance was better in LNG-IUS Group with 13 patients staying on their therapy versus seven patients in Depot MPA Group. LNG-IUS users had a significantly better change in BMD (+0.023, +0.071 g/cm(2)) than Depot MPA users (-0.030, -0.017 g/cm(2)) in both hip and lumbar regions. CONCLUSIONS Levonorgestrel-releasing intrauterine system was effective in symptom control and prevention of recurrence. LNG-IUS users showed a better compliance. After three years, bone gain was noted with LNG-IUS, but bone loss with depot MPA.

Abstract
Women who have survived cancer may need guidance in choosing a method of contraception. This paper reviews the evidence supporting the safety and efficacy of available methods of contraception for cancer survivors and concludes that the Copper T380A intrauterine device (IUD), a highly effective, reversible, long-acting, hormone-free method should be considered a first-line contraceptive option for women with a history of a hormonally mediated cancer. However, the levonorgestrel-containing IUD may be preferable for women being treated with tamoxifen and women who have survived non-hormonally mediated cancers. Women with IUDs can undergo all forms of imaging, including computed tomography and magnetic resonance imaging.

Abstract
OBJECTIVE It is recommended that women with systemic lupus erythematosus carefully time their pregnancies, but little is known about use of contraception and risk of unintended pregnancy in this population. The goal of this study was to estimate the proportion of women with lupus at risk for unintended pregnancy. METHODS We surveyed 309 women with lupus, ages 18-50 years, seen at the University of Pittsburgh lupus center between January and May 2007. RESULTS Of the women surveyed, 212 (69%) completed the survey. In the past 3 months, 97 (46% of 212) had faced some risk of unintended pregnancy. Of these, 53 (55% of 97) reported >or=1 occasion on which they had unprotected sex and 22 (23% of 97) reported that in the last 3 months they had unprotected sex "most of the time." No women reported having used emergency contraception after unprotected sex. A desire to "discuss birth control with a health care provider at the lupus center" was reported by 22 (10% of 212) respondents and 16 (17% of 94) women <or=35 years old. CONCLUSION Many women cared for by our lupus center are at risk of unintended pregnancy and are interested in discussing birth control with a health care provider.

Abstract
The levonorgestrel-containing intrauterine system is an extremely effective, reversible and safe form of long-term yet reversible birth control. In view of its efficacy, it is a safer alternative to permanent contraceptive methods such as sterilization. It is especially useful in situations where use of estrogen-containing contraceptives is contraindicated. While menstrual disturbances are a common side effect, proper counseling improves compliance. In addition to its contraceptive effect, the levonorgestrel intrauterine system offers potential therapeutic benefits in other clinical contexts, including menorrhagia, symptomatic fibroids, endometriosis, and endometrial protection.

Abstract
The effects of progestins on the quality of bone and their influence on the risk of fractures are reviewed. Data discussed are based on experimental studies in vivo that generally lasted for longer than one year. Information is given on the background of osteoporosis and on several means of inducing changes in bone quality. In young women who start using oral contraceptives based on progestins alone shortly after pubertal development, a significant decrease in bone quality has been documented. World Health Organization experts have concluded that this is not a real argument for restrictions on the use of these contraceptives. In postmenopausal women, no evidence has been found for a bone-protective or an estrogen-antagonistic effect of progestins. A wide range of estrogens have been used that have shown positive effects on bone, which are not antagonized by progestins. The therapeutic use of high-dose megestrol acetate may result in marked negative effects on bone, leading to severe osteoporosis, possibly due to the inherent glucocorticoid activity of this progestin. Other pharmacotherapeutic agents that can be used in postmenopausal therapy, and that clearly have beneficial effects on bone, are discussed.

Abstract
Since its launch in Finland in 1990, the levonorgestrel-releasing intrauterine system (LNG IUS) has become available in more than 100 countries throughout the world, with most countries also having the approval for the treatment of idiopathic menorrhagia and protection from endometrial hyperplasia during estrogen replacement therapy. After its introduction in Finland and Scandinavian countries, the LNG IUS has been available in most European countries since the mid to late 1990s and in the United States since 2001. Studies on the repeat use of the LNG IUS with second and third consecutive IUSs have shown high continuation rates and low rates of adverse effects. During repeat use of the LNG IUS, the bleeding pattern changes toward an increasing amenorrhea rate. With regard to the menorrhagia indication, the 5-year follow-up results of a randomized comparative trial of the LNG IUS and hysterectomy have shown equal satisfaction and improvement in health-related quality of life with both treatments. Although a proportion of women assigned to the LNG IUS group eventually underwent hysterectomy, the continuation rate of the LNG IUS for menorrhagia is clearly superior to that of conventional medical therapy (e.g., oral progestins). Use of the LNG IUS in combination with estrogen therapy in women undergoing menopausal transition seems to be well tolerated and associated with a favorable bleeding pattern.

Abstract
OBJECTIVES This report is a review of the medical literature on the use of the levonorgestrel-releasing intrauterine system (LNG-IUS) in women with endometriosis, adenomyosis, cyclic pelvic pain and dysmenorrhea. MATERIAL AND METHODS A review was carried out using the MEDLINE and EMBASE databases to evaluate the use of LNG-IUS in women with endometriosis and adenomyosis. RESULTS Nine studies were identified, only two of which were randomized clinical trials. One compared the insertion of LNG-IUS after surgery with expectant conduct and the other compared the use of the device with a GnRH analogue (GnRH-a). All studies reported an improvement in pelvic pain and dysmenorrhea, and a reduction in menstrual bleeding. One study found an improvement in the staging of the disease at 6 months of use, and the studies that evaluated the use of LNG-IUS in women with adenomyosis reported a reduction in uterine volume. Furthermore, the only study in which women were followed up for 3 years after insertion found improvement in pelvic pain at 12 months of use. However, there was no improvement after that period. CONCLUSIONS The use of LNG-IUS is an alternative for the medical treatment of women suffering from endometriosis, adenomyosis, chronic pelvic pain or dysmenorrhea, but experience is limited and long-term studies are necessary to reach definitive conclusions. However, for women who do not wish to become pregnant, this device offers the possibility of at least 5 years of treatment following one single intervention.

Abstract
During the transition years leading to menopause, the possibility of conception persists, although at a lower rate. Contraceptive choices available to perimenopausal women are as varied as those for their younger counterparts, albeit with some limitations related predominantly to coexisting medical conditions rather than the advancing age itself. In this review, different contraceptive choices pertaining to this age group will be discussed, with a focus on evidence-based data.

Abstract
A 72-year-old female with scirrhous-type advanced gastric cancer was treated with TS-1/CDDP as neoadjuvant chemotherapy. TS-1 (80 mg/m(2)/day) was orally administered for 3 weeks and CDDP (60 mg/m(2)) was administered by intravenous drip on day 8. Partial response (PR) was obtained after the first course, and total gastrectomy was performed. The histological diagnosis revealed complete disappearance of cancer cells in the stomach and a few regional lymph node metastases (3/67). The patient has now been in good health without a recurrence for 1 year and 9 months after surgery.
