Psychological effect of the oral contraceptive formulation containing 3 mg of drospirenone plus 30 microg of ethinyl estradiol

Symptoms of mental disorders and oral contraception use: A systematic review and meta-analysis

Worldwide, over 150 million adolescent and adult women use oral contraceptives (OC). An association between OC-use and the emergence of symptoms of mental disorders has been suggested. This systematic review and meta-analysis provide an overview of published research regarding symptoms of mental disorders in association with OC-use, factoring the influence of OC types, age of first-use, duration of OC-intake, and previous diagnoses of mental disorders. A systematic literature search was conducted between June-July 2022. 22 studies were included. While most found no significant OC-use effects on mental symptoms, some hinted at OCs as a potential risk. The existing evidence regarding the potential link between progestin-only OC-use and an elevated risk of mental symptoms in comparison to combined OC-use remains inconclusive. However, due to emerging indications suggesting that the formulation of OC might play a role in mental health outcomes, this topic warrants further investigation. Moreover, indications of an increased risk for depressive symptoms in adolescent OC-users should be noted. Hence, while general population effects seem unlikely, they cannot be completely disregarded. The decision on OC-use should depend on the patient's medical history and should be re-evaluated regularly.

Adrenocorticotropic hormone secretion in response to anticipatory stress and venepuncture: The role of menstrual phase and oral contraceptive use

INTRODUCTION

Oral contraceptives (OCs) are primarily known for their effects on the reproductive system, but they can also impact the hypothalamic-pituitary-adrenal (HPA) axis. The present study aimed to compare plasma adrenocorticotropic hormone (ACTH) responses to the anticipatory stress of participating in a scientific experiment and venepuncture in OC users versus naturally cycling (NC) women, with a focus on variations throughout the menstrual cycle.

METHODS

We recruited 131 young women (average age 20.5) and obtained blood samples to measure plasma ACTH concentrations immediately after venepuncture and again after 15 min of group activities designed to facilitate interpersonal attachment and stress-buffering.

RESULTS

ACTH levels decreased in 70% of all participants throughout the group activities. A two-way repeated measures ANOVA highlighted a significant interaction between time and OC use, indicating differential changes in ACTH levels during social interaction between OC users and NC women. Further, the post-hoc analysis revealed that a period of stress-buffering group activities significantly decreased ACTH levels in NC women during menstrual and secretory phases, but not during the proliferative phase. In contrast, OC users did not display a decrease during group activities, regardless of the phase.

CONCLUSION

This study underscores the influence of OC use on stress regulation, demonstrating that OCs not only modulate reproductive functions but also impact ACTH stress reactivity. Additionally, it emphasizes the importance of considering hormonal contraceptive use and menstrual cycle phases when assessing female stress responses.

Hormonal contraceptive exposure relates to changes in resting state functional connectivity of anterior cingulate cortex and amygdala

Introduction

Hormonal contraceptives (HCs), nowadays one of the most used contraceptive methods, downregulate endogenous ovarian hormones, which have multiple plastic effects in the adult brain. HCs usually contain a synthetic estrogen, ethinyl-estradiol, and a synthetic progestin, which can be classified as androgenic or anti-androgenic, depending on their interaction with androgen receptors. Both the anterior cingulate cortex (ACC) and the amygdala express steroid receptors and have shown differential functionality depending on the hormonal status of the participant and the use of HC. In this work, we investigated for the first time the relationship between ACC and amygdala resting state functional connectivity (rs-FC) and HC use duration, while controlling for progestin androgenicity.

Methods

A total of 231 healthy young women participated in five different magnetic resonance imaging studies and were included in the final analysis. The relation between HC use duration and (i) gray matter volume, (ii) fractional amplitude of low-frequency fluctuations, and (iii) seed-based connectivity during resting state in the amygdalae and ACC was investigated in this large sample of women.

Results

In general, rs-FC of the amygdalae with frontal areas, and between the ACC and temporoparietal areas, decreased the longer the HC exposure and independently of the progestin's androgenicity. The type of HC's progestin did show a differential effect in the gray matter volume of left ACC and the connectivity between bilateral ACC and the right inferior frontal gyrus.

Evaluations of memory, anxiety, and the growth factor IGF-1R after post-surgical menopause treatment with a highly selective progestin

Progestogens are a key component of menopausal hormone therapies. While some progestogens can be detrimental to cognition, there is preclinical evidence that progestogens with a strong progesterone-receptor affinity benefit some molecular mechanisms believed to underlie cognitive function. Thus, a progestin that maximizes progesterone-receptor affinity and minimizes affinities to other receptors may be cognitively beneficial. We evaluated segesterone-acetate (SGA), a 19-norprogesterone derivative with a strong progesterone-receptor affinity and no androgenic or estrogenic-receptor activity, hypothesizing that it would enhance cognition. Middle-aged rats underwent Sham or Ovariectomy (Ovx) surgery followed by administration of medroxyprogesterone-acetate (MPA; used as a positive control as we have previously shown MPA-induced cognitive deficits), SGA (low or high dose), or vehicle (one Sham and one Ovx group). Spatial working and reference memory, delayed retention, and anxiety-like behavior were assessed, as were memory- and hormone- related protein assays within the frontal cortex, dorsal hippocampus, and entorhinal cortex. Low-dose SGA impaired spatial working memory, while high-dose SGA had a more extensive detrimental impact, negatively affecting spatial reference memory and delayed retention. Replicating previous findings, MPA impaired spatial reference memory and delayed retention. SGA, but not MPA, alleviated Ovx-induced anxiety-like behaviors. On two working memory measures, IGF-1R expression correlated with better working memory only in rats without hormone manipulation; any hormone manipulation or combination of hormone manipulations used herein altered this relationship. These findings suggest that SGA impairs spatial cognition after surgical menopause, and that surgical menopause with or without progestin administration disrupts relationships between a growth factor critical to neuroplasticity.

Mood disorders and hormonal status across women's life: a narrative review

Depressive disorders and anxiety states represent one of the most frequent psychiatric pathologies occurring transiently in vulnerable women throughout their life, from puberty to menopause. It is now known that sex hormones play a key role on the nervous system, interfering with neuronal plasticity and enhancing the processes of learning, memory, cognition, and mood. Numerous mechanisms are at the base of these processes, displaying interactions between estrogen and serotoninergic, dopaminergic, and GABAergic receptors at the central level. Therefore, given the sexual steroids fluctuations throughout the entire female lifespan, and considering the role played by sex hormones at the central level, it is not surprising to observe the onset of mood or neurodegenerative disorders over time. This is especially true for women in hormonal transition phase, such as puberty, postpartum and the menopausal transition. Moreover, all these conditions are characterized by hormone withdrawal, imbalance, or modifications due to menopausal hormone therapies or contraceptives which could prompt to a deterioration of mood and cognition impairment or to an improvement in the quality of life. More studies are needed to better understand the hormone-related effects on the nervous system, and the underlying pathways involved in transitional or chronic mood disorders, to promote new patient-specific therapeutic strategies more effective than the current ones and tailored according to the individual need and women's life period.

What is there to know about the effects of progestins on the human brain and cognition?

Progestins are an important component of hormonal contraceptives (HCs) and hormone replacement therapies (HRTs). Despite an increasing number of studies elucidating the effects of HCs and HRTs, little is known about the effects of different types of progestins included in these medications on the brain. Animal studies suggest that various progestins interact differently with sex steroid, mineralocorticoid and glucocorticoid receptors and have specific modulatory effects on neurotransmitter systems and on the expression of neuropeptides, suggesting differential impacts on cognition and behavior. This review focuses on the currently available knowledge from human behavioral and neuroimaging studies pooled with evidence from animal research regarding the effects of progestins on the brain. The reviewed information is highly relevant for improving women's mental health and making informed choices regarding specific types of contraception or treatment.

The Allopregnanolone Response to Acute Stress in Females: Preclinical and Clinical Studies

The neuroactive steroid allopregnanolone ((3α,5α)-3-hydroxypregnan-20-one or 3α,5α-THP) plays a key role in the response to stress, by normalizing hypothalamic-pituitary-adrenal (HPA) axis function to restore homeostasis. Most studies have been conducted on male rats, and little is known about the allopregnanolone response to stress in females, despite that women are more susceptible than men to develop emotional and stress-related disorders. Here, we provide an overview of animal and human studies examining the allopregnanolone responses to acute stress in females in the context of stress-related neuropsychiatric diseases and under the different conditions that characterize the female lifespan associated with the reproductive function. The blunted allopregnanolone response to acute stress, often observed in female rats and women, may represent one of the mechanisms that contribute to the increased vulnerability to stress and affective disorders in women under the different hormonal fluctuations that occur throughout their lifespan. These studies highlight the importance of targeting neuroactive steroids as a therapeutic approach for stress-related disorders in women.

Chronic treatment with hormonal contraceptives alters hippocampal BDNF and histone H3 post-translational modifications but not learning and memory in female rats

Hormonal contraceptives prevent ovulation with subsequent reduction in endogenous levels of estradiol, progesterone and its neuroactive metabolite allopregnanolone. These neurosteroids modulate several brain functions, including neuronal plasticity, cognition and memory. We hypothesized that hormonal contraceptives might affect synaptic plasticity, learning and memory, as a consequence of suppressed endogenous hormones levels. Female rats were orally treated with a combination of ethinyl estradiol (EE, 0.020 mg) and levonorgestrel (LNG, 0.060 mg) once daily for four weeks. Decreased hippocampal brain-derived neurotrophic factor (BDNF) levels and altered histone H3 post-translational modifications (PTMs) were observed 14 days after discontinuation from chronic EE-LNG treatment. These effects were not accompanied by alterations in long-term plasticity at glutamatergic synapses, recognition memory in the novel object and novel place location tests, or spatial learning, memory, and behavioral flexibility in the Morris water maze test. Thus, decreased BDNF content does not affect synaptic plasticity and cognitive performance; rather it might be relevant for the occurrence of certain psychiatric symptoms, reported by some women using hormonal contraceptives. These results provide the first evidence of hippocampal epigenetic changes induced by hormonal contraceptives and complement previous studies on the neurobiological actions of hormonal contraceptives; the finding that effects of chronic EE-LNG treatment on BDNF content and histone PTMs are observed 14 days after drug discontinuation warrants further investigation to better understand the implications of such long-term consequences for women's health.

How hormonal contraceptives shape brain and behavior: A review of preclinical studies

Steroid hormones influence different aspects of brain function, including development, neurogenesis, neuronal excitability, and plasticity, thus affecting emotional states, cognition, sociality, and reward. In women, their levels fluctuate across the lifespan and through the reproductive stages but are also altered by exogenous administration of hormonal contraceptives (HC). HC are widely used by women throughout their fertile life both for contraceptive and therapeutic benefits. However, awareness of their effects on brain function and behavior is still poorly appreciated, despite the emerging evidence of their action at the level of the central nervous system. Here, we summarize results obtained in preclinical studies, mostly conducted in intact female rodents, aimed at investigating the neurobiological effects of HC. HC can alter neuroactive hormones, neurotransmitters, neuropeptides, as well as emotional states, cognition, social and sexual behaviors. Animal studies provide insights into the neurobiological effects of HC with the aim to improve women's health and well-being.

Evaluating the Cognitive Impacts of Drospirenone, a Spironolactone-Derived Progestin, Independently and in Combination With Ethinyl Estradiol in Ovariectomized Adult Rats

Oral contraceptives and hormone therapies require a progestogen component to prevent ovulation, curtail uterine hyperplasia, and reduce gynecological cancer risk. Diverse classes of synthetic progestogens, called progestins, are used as natural progesterone alternatives due to progesterone’s low oral bioavailability. Progesterone and several synthetic analogs can negatively impact cognition and reverse some neuroprotective estrogen effects. Here, we investigate drospirenone, a spironolactone-derived progestin, which has unique pharmacological properties compared to other clinically-available progestins and natural progesterone, for its impact on spatial memory, anxiety-like behavior, and brain regions crucial to these cognitive tasks. Experiment 1 assessed three drospirenone doses in young adult, ovariectomized rats, and found that a moderate drospirenone dose benefited spatial memory. Experiment 2 investigated this moderate drospirenone dose with and without concomitant ethinyl estradiol (EE) treatment, the most common synthetic estrogen in oral contraceptives. Results demonstrate that the addition of EE to drospirenone administration reversed the beneficial working memory effects of drospirenone. The hippocampus, entorhinal cortex, and perirhinal cortex were then probed for proteins known to elicit estrogen- and progestin- mediated effects on learning and memory, including glutamate decarboxylase (GAD)65, GAD67, and insulin-like growth factor receptor protein expression, using western blot. EE increased GAD expression in the perirhinal cortex. Taken together, results underscore the necessity to consider the distinct cognitive and neural impacts of clinically-available synthetic estrogen and progesterone analogs, and why they produce unique cognitive profiles when administered together compared to those observed when each hormone is administered separately.

Premenstrual Syndrome and Premenstrual Dysphoric Disorder as Centrally Based Disorders

Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) encompass a variety of symptoms that occur during the luteal phase of the menstrual cycle and impair daily life activities and relationships. Depending on the type and severity of physical, emotional or behavioral symptoms, women of reproductive age followed for at least two prospective menstrual cycles may receive one of the two diagnoses. PMDD is the most severe form of PMS, predominantly characterized by emotional and behavioral symptoms not due to another psychiatric disorder. PMS and PMDD are common neuro-hormonal gynecological disorders with a multifaceted etiology. Gonadal steroid hormones and their metabolites influence a plethora of biological systems involved in the occurrence of specific symptoms, but there is no doubt that PMS/PMDD are centrally based disorders. A more sensitive neuroendocrine threshold to cyclical variations of estrogens and progesterone under physiological and hormonal therapies is present. Moreover, altered brain sensitivity to allopregnanolone, a metabolite of progesterone produced after ovulation potentiating GABA activity, along with an impairment of opioid and serotoninergic systems, may justify the occurrence of emotional and behavioral symptoms. Even neuro-inflammation expressed via the GABAergic system is under investigation as an etiological factor of PMS/PMDD. Pharmacological management aims to stabilize hormonal fluctuations and to restore the neuroendocrine balance. The rationale of suppressing ovulation supports prescription of combined hormonal contraception (CHC). Its effect on mood is highly variable and depends on biochemical characteristics of exogenous steroids and on type and severity of symptoms. Hormonal regimens reducing the estrogen-free interval or suppressing menstruation seem better choices. Psychoactive agents, such as serotonin reuptake inhibitors (SSRIs), are effective in reducing the symptoms of PMS/PMDD and may be prescribed continuously or only during the luteal phase. Novel therapeutic approaches include inhibition of progesterone receptors in the brain, i.e., with ulipristal acetate, reduced conversion of progesterone with dutasteride, and modulation of the action of allopregnanolone on the brain GABAergic system with sepranolone.

Hormonal Contraception and Depression: Updated Evidence and Implications in Clinical Practice

Hormonal contraceptives are used worldwide by more than 100 million women. Some studies have been published about the possible appearance of depressive symptoms when using hormonal contraceptives, but this link is still a matter of debate. The purpose of this review is to provide an update of the literature on this issue, and to investigate the possible explanations of this problem based on animal and human studies. The main pathway responsible for menstrual cycle-related mood changes is the γ-aminobutyric acid pathway, which is sensitive to changes in the levels of progesterone and of its metabolites, the neurosteroids. In particular, allopregnanolone is a potentiating neurosteroid with anxiolytic and anti-convulsant effects whose levels change during a normal menstrual cycle together with progesterone levels. Progestins have different effects on allopregnanolone, mainly owing to their diverse androgenicity. Moreover, they might affect brain structure and function, even though the meaning of these changes has yet to be clarified. It is important to define the groups of women in which negative mood disorders are more likely to occur. Adolescence is a critical period and this age-specific vulnerability is complex and likely bidirectional. Moreover, women with a history of mood affective disorders or premenstrual dysphoric syndrome are at a higher risk when taking contraceptives. In this review, we aim to provide clinicians with advice on how to approach these difficult situations.

The brain as a target of hormonal contraceptives: Evidence from animal studies

Hormonal contraceptives are frequently prescribed drugs among women, mainly for their reversible contraceptive purposes but also for beneficial effects in some gynecological pathologies. Despite extensive studies aimed at elucidating the physical effects of hormonal contraceptives and ameliorating some unwanted outcomes, little is known yet about the effects of these drugs on brain function and related behavior, which are known to be modulated by endogenous steroid hormones. We describe the current literature on preclinical studies in animals undertaken to investigate effects of hormonal contraceptives on brain function and behavior. These studies suggest that hormonal contraceptives influence neurohormones, neurotransmitters, neuropeptides, and emotional, cognitive, social and sexual behaviors. Animals allow examination of the basic biological mechanisms of these drugs, devoid of the psychological aspect often associated to hormonal contraceptives' use in women. Understanding the neurobiological effects of these drugs may improve women's health and may help women making informed choices on hormonal contraception.

Body composition and psychological improvement in healthy premenopausal women assuming the oral contraceptive containing micronized estradiol (E2) and nomegestrol acetate (NOMAC)

This observational study was conducted in healthy premenopausal women, who presented themselves for contraceptive advice at the outpatient Family Planning Clinics of the Department of Obstetrics and Gynecology of the University of Cagliari, Hospital-University of Cagliari (Italy). After a screening period of three menstrual cycles, 48 women without contraindications to estroprogestin contraceptives (OCs) were included in the study. The primary purposes of the study were to evaluate whether a 12-month-treatment with the combined OC containing micronized estradiol (1.5 mg, E2) plus nomegestrol acetate (2.5 mg, NOMAC) (E2/NOMAC) interfere on anthropometric indices (AI), body composition (BC) and psychological status (PS). In subjects with dysmenorrhea (#36), its intensity was evaluated using the visuo analogic scale (VAS), both before and during the 12-month-treatment with E2/NOMAC. E2/NOMAC did not modify neither AI nor BC in the 40 subjects who concluded the study. The PS and the VAS of dysmenorrhea were significantly (p < 0.0001) improved from the first cycle of treatment and throughout the E2/NOMAC treatment in comparison with basal values. The study suggests that E2/NOMAC is devoid of negative effects on AI and BC, with additional benefits on PS and dysmenorrhea.

Improvement of Low Sexual Desire Due to Antiandrogenic Combined Oral Contraceptives After Switching to an Oral Contraceptive Containing 17β-Estradiol

OBJECTIVES

To investigate the effects of a combined oral contraceptive (COC) containing 17β-estradiol (E2) 1.5 mg and nomegestrol acetate 2.5 mg (NOMAC/E2) on the sexual health of women affected by low sexual desire due to COCs containing ethinylestradiol.

MATERIALS AND METHODS

Eighty-three women (age range 19-32) participated in the study. Sex hormone-binding globulin (SHBG), total testosterone (TT), and free androgen index (FAI) were measured. The Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires were used to assess sexual function and distress, respectively. Hormonal levels were measured and questionnaires were administered before the women switched COC NOMAC/E2 usage (baseline) and at the 3-month (first) and 6-month (second) follow-ups.

RESULTS

SHBG reduction (p < 0.001), TT (p < 0.05), and FAI increases (p < 0.001) were observed during the first and second follow-ups with respect to baseline values. Sexual desire increased from baseline to the first and second follow-ups (p < 0.001). At baseline, the total FSFI score was 22 ± 1.5 and the FSDS score was 16.6 ± 1.3, both indicating sexual dysfunction with sexual distress. At the first follow-up, the total FSFI score and the FSDS score increased toward sexual health values, being 28.3 ± 1.6 and 12.1 ± 1.5, respectively (p < 0.001). At the second follow-up, the FSFI score had risen to 30.6 ± 1.3 (p < 0.001) and the FSDS score had dropped to 8.3 ± 1.4 (p < 0.001).

CONCLUSIONS

COCs containing E2 are an innovation that could help women to not suffer from low sexual desire during hypoandrogenic COC usage.

Combined oral contraceptive use is associated with both improvement and worsening of mood in the different phases of the treatment cycle-A double-blind, placebo-controlled randomized trial

OBJECTIVE

Ever since the introduction of combined oral contraception (COC), one of the major reasons for discontinuing the pill use has been mood-related side effects. Moreover, women who discontinue the pill turn to less effective methods whereby the probability of an unintended conception increases. Approximately 4-10% of COC users complain of depressed mood, irritability or increased anxiety, but drug-related causality has been difficult to prove. Given the lack of randomized controlled trials in this area, we aimed to prospectively estimate the severity of adverse mood in COC users that would be as representative of general users as possible.

METHODS

This investigator-initiated, multi-center, randomized, double-blinded, placebo-controlled study included 202 healthy women. Women were randomized to a COC (1.5mg estradiol and 2.5mg nomegestrolacetate) or placebo for three treatment cycles. Main outcome measure was the Daily Record of Severity of Problems (DRSP), which was filled out daily during one baseline cycle and the final treatment cycle.

RESULTS

Results from 84 women in the COC group and 94 women in the placebo group were analysed. COC use was associated with small, but statistically significant, increases in mean anxiety (0.22; 95% CI: 0.07-0.37, p=0.003), irritability (0.23; 95% CI: 0.07-0.38, p=0.012), and mood swings scores (0.15; 95% CI: 0.00-0.31, p=0.047) during the intermenstrual phase, but a significant premenstrual improvement in depression (-0.33; 95% CI: -0.62 to -0.05, p=0.049). Secondary analyses showed that women with previous adverse hormonal contraceptive experience reported significantly greater mood worsening in the intermenstrual phase in comparison with healthy women, p<0.05. The proportion of women who reported a clinically relevant mood deterioration did not differ between those allocated to COC (24.1%) or placebo (17.0%), p=0.262.

CONCLUSION

COC use is associated with small but statistically significant mood side effects in the intermenstrual phase. These findings are driven by a subgroup of women who clearly suffer from COC-related side effects. However, positive mood effects are noted in the premenstrual phase and the proportion of women with clinically relevant mood worsening did not differ between treatment groups.

The other side of progestins: effects in the brain

Progestins are a broad class of progestational agents widely differing in their chemical structures and pharmacological properties. Despite emerging data suggest that progestins, besides their action as endometrial protection, can also have multiple nonreproductive functions, much remains to be discovered regarding the actions exerted by these molecules in the nervous system. Here, we report the role exerted by different progestins, currently used for contraception or in postmenopausal hormone replacement therapies, in regulating cognitive functions as well as social behavior and mood. We provide evidence that the effects and mechanisms underlying their actions are still confusing due to the use of different estrogens and progestins as well as different doses, duration of exposure, route of administration, baseline hormonal status and age of treated women. We also discuss the emerging issue concerning the relevant increase of these substances in the environment, able to deeply affect aquatic wildlife as well as to exert a possible influence in humans, which may be exposed to these compounds via contaminated drinking water and seafood. Finally, we report literature data showing the neurobiological action of progestins and in particular their importance during neurodegenerative events. This is extremely interesting, since some of the progestins currently used in clinical practice exert neuroprotective and anti-inflammatory effects in the nervous system, opening new promising opportunities for the use of these molecules as therapeutic agents for trauma and neurodegenerative disorders.

Psychological, social, and spiritual effects of contraceptive steroid hormones

Governments and society have accepted and enthusiastically promoted contraception, especially contraceptive steroid hormones, as the means of assuring optimal timing and number of births, an undoubted health benefit, but they seldom advert to their limitations and side effects. This article reviews the literature on the psychological, social, and spiritual impact of contraceptive steroid use. While the widespread use of contraceptive steroid hormones has expanded life style and career choices for many women, their impact on the women's well-being, emotions, social relationships, and spirituality is seldom mentioned by advocates, and negative effects are often downplayed. When mentioned at all, depression and hypoactive sexual desire are usually treated symptomatically rather than discontinuing their most frequent pharmacological cause, the contraceptive. The rising incidence of premarital sex and cohabitation and decreased marriage rates parallel the use of contraceptive steroids as does decreased church attendance and/or reduced acceptance of Church teaching among Catholics. Lay summary: While there is wide, societal acceptance of hormonal contraceptives to space births, their physical side effects are often downplayed and their impact on emotions and life styles are largely unexamined. Coincidental to the use of "the pill" there has been an increase in depression, low sexual desire, "hook-ups," cohabitation, delay of marriage and childbearing, and among Catholics, decreased church attendance and reduced religious practice. Fertility is not a disease. Birth spacing can be achieved by natural means, and the many undesirable effects of contraception avoided.

Decreased allopregnanolone induced by hormonal contraceptives is associated with a reduction in social behavior and sexual motivation in female rats

RATIONALE

Allopregnanolone is a neurosteroid involved in depression, memory, social, and sexual behavior. We have previously demonstrated that treatment with a combination of ethinylestradiol (EE) and levonorgestrel (LNG), two compounds frequently used in hormonal contraception, decreased brain allopregnanolone concentrations. These changes may contribute to some of the emotional and sexual disorders observed in hormonal contraceptive users.

OBJECTIVES

We thus examined whether the reduction in allopregnanolone concentrations induced by long-term EE/LNG administration was associated with altered emotional, learning, social, and sexual behaviors.

METHODS

Rats were orally treated with a combination of EE (0.030 mg) and LNG (0.125 mg) once a day for 4 weeks and were subjected to behavioral tests 24 h after the last administration.

RESULTS

EE/LNG treatment reduced immobility behavior in the forced swim test, without affecting sucrose preference and spatial learning and memory. In the resident-intruder test, EE/LNG-treated rats displayed a decrease in dominant behaviors associated with a reduction in social investigation. In the paced mating test, EE/LNG treated rats showed a reduction in proceptive behaviors, while the lordosis quotient was not affected. Progesterone, but not estradiol, administration to EE/LNG-treated rats increased sexual activity and cerebrocortical allopregnanolone concentrations. Prior administration of finasteride decreased allopregnanolone concentrations and abolished the increase in proceptivity induced by progesterone administration.

CONCLUSIONS

The decrease in brain allopregnanolone concentrations induced by EE/LNG treatment is associated with a reduction in social behavior and sexual motivation in female rats. These results might be relevant to the side effects sometimes exhibited by women taking hormonal contraceptives.

Oral contraceptive use changes brain activity and mood in women with previous negative affect on the pill--a double-blinded, placebo-controlled randomized trial of a levonorgestrel-containing combined oral contraceptive

OBJECTIVE

Most women on combined oral contraceptives (COC) report high levels of satisfaction, but 4-10% complain of adverse mood effects. The aim of this randomized, double-blinded, placebo-controlled trial was to investigate if COC use would induce more pronounced mood symptoms than placebo in women with previous history of COC-induced adverse mood. A second aim was to determine if COC use is associated with changes in brain reactivity in regions previously associated with emotion processing.

METHODS

Thirty-four women with previous experience of mood deterioration during COC use were randomized to one treatment cycle with a levonorgestrel-containing COC or placebo. An emotional face matching task (vs. geometrical shapes) was administered during functional magnetic resonance imaging (fMRI) prior to and during the COC treatment cycle. Throughout the trial, women recorded daily symptom ratings on the Cyclicity Diagnoser (CD) scale.

RESULTS

During the last week of the treatment cycle COC users had higher scores of depressed mood, mood swings, and fatigue than placebo users. COC users also had lower emotion-induced reactivity in the left insula, left middle frontal gyrus, and bilateral inferior frontal gyri as compared to placebo users. In comparison with their pretreatment cycle, the COC group had decreased emotion-induced reactivity in the bilateral inferior frontal gyri, whereas placebo users had decreased reactivity in the right amygdala.

CONCLUSION

COC use in women who previously had experienced emotional side effects resulted in mood deterioration, and COC use was also accompanied by changes in emotional brain reactivity. These findings are of relevance for the understanding of how combined oral contraceptives may influence mood. Placebo-controlled fMRI studies in COC sensitive women could be of relevance for future testing of adverse mood effects in new oral contraceptives.

A comparative efficacy of low-dose combined oral contraceptives containing desogestrel and drospirenone in premenstrual symptoms

Objective. To compare the efficacy of low-dose COC containing desogestrel (DSG) with drospirenone (DRSP) in the changes of premenstrual symptoms. Methods. In an open-label randomized controlled trial, 90 women with premenstrual syndrome who required COC were randomly recruited and allocated equally to receive either 6 cycles of 20 micrograms ethinyl estradiol (EE)/150 micrograms DSG (DSG group) or 20 micrograms EE/3 mg DRSP (DRSP group) in 24/4 extended regimen. Analysis of covariance and repeated analysis of variance were used to determine the difference of mean Women's Health Assessment Questionnaire (WHAQ) scores changes between groups, within group, and in premenstrual, menstrual, and postmenstrual phases. Results. Baseline characteristics and WHAQ scores were comparable. At the ends of the 3rd and the 6th cycles, mean WHAQ scores of all the 3 phases in DRSP group showed significant reduction and were significantly lower than those in DSG group. DSG group showed significant reduction in both premenstrual and menstrual phases after the 6th cycle. Adverse effects were comparable in both groups. In conclusion, low-dose COC containing either DSG or DRSP reduced premenstrual symptoms, but the latter showed greater efficacy and earlier reduction.

Long-term administration with levonorgestrel decreases allopregnanolone levels and alters GABA(A) receptor subunit expression and anxiety-like behavior

Fluctuations in the concentrations of the neuroactive steroid allopregnanolone are thought to influence γ-amino-butyric acid type A (GABA(A)) receptor gene expression and function. Long-term treatment with ethinyl estradiol (EE) plus levonorgestrel (LNG), two of the most widely used steroids in the hormonal contraceptive pill, decreases allopregnanolone levels in rat cerebral cortex and plasma, alters GABA(A) receptor expression and induces anxiety-like behavior. We evaluated which component of the hormonal contraceptive pill is responsible for the aforementioned changes. Female rats were injected subcutaneously (s.c.) with EE (0.030 mg) or LNG (0.125 mg) once a day for 4 weeks. Compared to the respective vehicle-treated control groups, EE decreased cerebral cortical levels of allopregnanolone, progesterone and pregnenolone by 76, 72 and 33%, respectively and hippocampal levels by 52, 56 and 50%, respectively. Likewise, LNG decreased cerebral cortical levels of allopregnanolone, progesterone and pregnenolone by 75, 68 and 33%, respectively, and hippocampal levels by 55, 65 and 60%, respectively. Administration of LNG, but not EE, increased the abundance of the γ2 subunit peptide in cerebral cortex and hippocampus by 38 and 59%, respectively. Further, LNG, but not EE, decreased the time spent and the number of entries into the open arms of the elevated plus maze by 56 and 43%, respectively, an index of anxiety-like behavior. These results suggest that alterations in GABA(A) receptor subunit expression and anxiety-like behavior induced by long-term treatment with combined EE/LNG appear to be caused by LNG. Given that both EE and LNG decrease allopregnanolone levels in a similar manner, these results further suggest that changes in allopregnanolone levels are not associated with GABA(A) receptor expression.

Oral contraceptives containing drospirenone for premenstrual syndrome

BACKGROUND

Premenstrual syndrome (PMS) is a common problem. Premenstrual dysphoric disorder (PMDD) is a severe form of premenstrual syndrome. Combined oral contraceptives, which provide both progestin and estrogen, have been examined for their ability to relieve premenstrual symptoms. An oral contraceptive containing drospirenone and a low estrogen dose has been approved for treating PMDD in women who choose oral contraceptives for contraception.

OBJECTIVES

To review all randomized controlled trials comparing a combined oral contraceptive containing drospirenone to a placebo or another combined oral contraceptive for effect on premenstrual symptoms.

SEARCH METHODS

We searched for studies of drospirenone and premenstrual syndrome in the following databases: Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, and POPLINE (20 Dec 2011); EMBASE, LILACS, PsycINFO, ClinicalTrials.gov, and the International Clinical Trials Registry Platform (ICTRP) of the World Health Organization (02 Mar 2011). We also examined references lists of relevant articles and wrote to known investigators to find other trials.

We included randomized controlled trials in any language that compared a combined oral contraceptive (COC) containing drospirenone with a placebo or with another COC for effect on premenstrual symptoms. The primary outcome included affective and physical premenstrual symptoms that were prospectively recorded. Adverse events related to combined oral contraceptive use were examined.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed study quality. For continuous variables, the mean difference (MD) was computed with 95% confidence interval (CI). For dichotomous outcomes, the Peto odds ratio (OR) with 95% CI was calculated.

MAIN RESULTS

We included five trials with a total of 1920 women. Two placebo-controlled trials of women with PMDD showed less severe premenstrual symptoms after three months with drospirenone 3 mg plus ethinyl estradiol 20 μg than with placebo (MD -7.92; 95% CI -11.16 to -4.67). The drospirenone group had greater mean decreases in impairment of productivity (MD -0.31; 95% CI -0.55 to -0.08), social activities (MD -0.29; 95% CI -0.54 to -0.04), and relationships (MD -0.30; 95% CI -0.54 to -0.06). Side effects more common with the use of the drospirenone COC contraceptive were nausea, intermenstrual bleeding, and breast pain. The respective odds ratios were 3.15 (95% CI 1.90 to 5.22), 4.92 (95% CI 3.03 to 7.96), and 2.67 (95% CI 1.50 to 4.78). Total adverse events related to the study drug were more likely for the drospirenone COC group (OR 2.36; 95% CI 1.62 to 3.44). Three trials studied the effect of drospirenone 3 mg plus ethinyl estradiol 30 μg on less severe symptoms. A placebo-controlled six-month trial had insufficient data for primary outcome analysis. Another six-month study used levonorgestrel 150 µg plus ethinyl estradiol 30 µg for the comparison group but did not provide enough data on premenstrual symptoms. In a two-year trial, the drospirenone COC group had similar premenstrual symptoms to the comparison group given desogestrel 150 µg plus ethinyl estradiol 30 µg (OR 0.87; 95% CI 0.63 to 1.22). The groups were also similar for adverse events related to treatment (OR 1.02; 95% CI 0.78 to 1.33).

AUTHORS' CONCLUSIONS

Drospirenone 3 mg plus ethinyl estradiol 20 μg may help treat premenstrual symptoms in women with severe symptoms, that is, premenstrual dysphoric disorder. The placebo also had a large effect. We do not know whether the combined oral contraceptive works after three cycles, helps women with less severe symptoms, or is better than other oral contraceptives. Larger and longer trials of higher quality are needed to address these issues. Trials should follow CONSORT guidelines.

Beyaz®: An Oral Contraceptive Fortified with Folate

Beyaz® (Bayer Healthcare Pharmaceuticals, Berlin, Germany) consists of 28 film-coated tablets: 24 tablets each containing 3 mg drospirenone plus 20 µg ethinylestradiol (EE) and 451 µg levomefolate calcium followed by four tablets, each containing 451 µg levomefolate calcium. It has the same indications of the parent compound 20 µg EE/3 mg drospirenone in a 24/4-day regimen (i.e., contraception, moderate acne, premenstrual dysforic disorder). In addition, the 24-day regimen with 20 µg EE/3 mg drospirenone/levomefolate calcium assure significant increases in red blood cell and plasma folate levels reaching values indicated to be protective in reducing the risk of neural tube defects. A progressive decrease in folate levels has been observed in women taking a 30 µg EE pill fortified with the same dose of levomefolate calcium upon discontinuation. At 4 and 8 weeks following cessation of the oral contraceptive, red blood cell folate levels >906 nmol/l were measured in 85 and 60% of women respectively. Because of this, the folate-containing pill may aid in reducing the risk of neural tube defects in a pregnancy conceived during use or shortly after the discontinuation of the product.

Oral contraceptives containing drospirenone for premenstrual syndrome

BACKGROUND

Premenstrual syndrome (PMS) is a common problem. Premenstrual dysphoric disorder (PMDD) is a severe form of PMS. Combined oral contraceptives (COCs), which have both progestin and estrogen, have been examined for their ability to relieve premenstrual symptoms. A COC containing drospirenone and low estrogen has been approved for treating PMDD in women who choose COCs for contraception.

OBJECTIVES

To review all randomized controlled trials comparing combined oral contraceptives containing drospirenone versus a placebo or another COC for effect on premenstrual symptoms.

SEARCH STRATEGY

We searched the computerized databases MEDLINE, POPLINE, CENTRAL, EMBASE, LILACS, PsycINFO, and CINAHL for studies of drospirenone and premenstrual syndrome. We also examined references lists of relevant articles, and wrote to known investigators to find other trials.

SELECTION CRITERIA

We included randomized controlled trials in any language that compared a COC containing drospirenone versus a placebo or another COC for effect on premenstrual symptoms. Primary outcome was the prospective recording of premenstrual symptoms (affective and physical). Adverse events related to COC use were examined.

DATA COLLECTION AND ANALYSIS

Two review authors independently abstracted data and assessed study quality.

MAIN RESULTS

We included five trials with a total of 1600 women. Two placebo-controlled trials of women with PMDD showed less severe premenstrual symptoms after three months with drospirenone (plus ethinyl estradiol (EE) 20g) than with the placebo (WMD -7.83; 95% CI -10.91 to -4.75). The drospirenone group had greater decreases in impairment of productivity (WMD -0.42; 95% CI -0.64 to -0.20), social activities (WMD -0.39; 95% CI -0.62 to -0.15), and relationships (WMD -0.38; 95% CI -0.61 to -0.51). Side effects more common with COC use were nausea, intermenstrual bleeding, and breast pain. Little effect was found on less severe symptoms when comparing drospirenone plus more estrogen to another COC. A six-month study showed fewer symptoms with drospirenone, while a two-year trial found the groups to be similar.

AUTHORS' CONCLUSIONS

Drospirenone plus EE 20 mug may help treat premenstrual symptoms in women with PMDD. The placebo also had a large effect. We do not know whether the COC works after three cycles, for women with less severe symptoms, or better than other COCs. Larger and longer trials of higher quality are needed to address these issues. Trials should follow CONSORT reporting guidelines.

The role of sex steroids in catamenial epilepsy and premenstrual dysphoric disorder: implications for diagnosis and treatment

Despite our understanding of hormonal influences on central nervous system (CNS) function, there is still much to learn about the pathogenesis of menstrual cycle-linked disorders. A growing literature suggests that the influence of sex steroids on neurological and psychiatric disorders is in part mediated by an aberrant CNS response to neuroactive steroids. Although sex steroids such as estradiol, progesterone, and the progesterone derivative allopregnanolone (ALLO) influence numerous neurotransmitter systems, it is their potent effect on the brain's primary inhibitory and excitatory neurotransmitters gamma-aminobutyric acid (GABA) and glutamate that links the study of premenstrual dysphoric disorder (PMDD) and catamenial epilepsy (CE). After providing an overview of these menstrual cycle-linked disorders, this article focuses on the preclinical and clinical research investigating the role of estradiol and progesterone (via ALLO) in the etiology of PMDD and CE. Through exploration of the phenomenological and neurobiological overlap between CE and PMDD, we aim to highlight areas for future research and development of treatments for menstrual cycle-linked neuropsychiatric disorders.

Effects of allopregnanolone on sedation in men, and in women on oral contraceptives

Allopregnanolone is a known GABA(A) receptor agonist not previously given to men, or to women using oral contraceptives (OC). The effects of metabolites of sex hormones on the GABA(A) receptor are different between men and women. OC are known to change GABA(A) receptor subunit composition. These factors might play a role in the differential effect of allopregnanolone in men and women, and in women with or without OC. To study the sedative effect of and sensitivity to allopregnanolone in men and in women with OC, nine healthy men (mean age 24.6 years) and nine healthy women on OC (mean age 21.8 years) were given three, increasing, intravenous dosages (0.015, 0.03, and 0.045 mg/kg) of allopregnanolone. Saccadic eye velocity (SEV), subjective ratings, and electroencephalography (EEG) were used to evaluate the response to allopregnanolone. Repeated blood samples for analyses of serum allopregnanolone levels were drawn throughout the study day. Allopregnanolone decreased SEV more in women than in men, and increased subjective ratings of 'sedation'. The results in women on OC are similar to earlier results in women without OC. Subjective ratings of 'contentedness' decreased in men but increased in women. Serum levels of allopregnanolone were more highly increased in men compared to women. Other pharmacokinetic parameters were not different between sexes. On the EEG, beta power increased in men. In conclusion, men and women on OC reacted differently to allopregnanolone.

Drospirenone increases central and peripheral β-endorphin in ovariectomized female rats

OBJECTIVE

Drospirenone is the unique progestin derived from 17-spironolactone used for contraception and hormone therapy. Few data are available concerning the effects of drospirenone on the central nervous system and neuroendocrine milieu. The opioid beta-endorphin and the neurosteroid allopregnanolone are considered markers of neuroendocrine functions, and their synthesis and activity are regulated by gonadal steroids. The aim of the present study was to evaluate the effect of a 2-week oral treatment with drospirenone, estradiol valerate, and combined therapy of drospirenone + estradiol valerate on central and peripheral beta-endorphin and allopregnanolone levels in ovariectomized female rats.

DESIGN

Seven groups of Wistar ovariectomized rats received oral drospirenone (0.1, 0.5, and 1.0 mg/kg per day), estradiol valerate (0.05 mg/kg per day), or drospirenone (0.1, 0.5, and 1.0 mg/kg per day) + estradiol valerate (0.05 mg/kg per day). One group of fertile and one group of ovariectomized rats were used as controls. beta-endorphin levels were measured in frontal and parietal lobes, hippocampus, hypothalamus, anterior and neurointermediate pituitary, and plasma, and allopregnanolone content was assessed in frontal and parietal lobes, hippocampus, hypothalamus, anterior pituitary, adrenal glands, and serum.

RESULTS

Ovariectomy induced a significant decrease in beta-endorphin and allopregnanolone content in all brain areas analyzed and in circulating levels, whereas it increased allopregnanolone content in the adrenal gland. Estradiol valerate replacement increased beta-endorphin and allopregnanolone levels in all brain areas analyzed and in plasma/serum. Drospirenone treatment significantly increased beta-endorphin levels in all brain areas analyzed (with the only exception being the parietal lobe), whereas it produced no effect on allopregnanolone levels. The addition of drospirenone to estradiol valerate did not modify the effects of estradiol valerate on beta-endorphin or allopregnanolone levels. Drospirenone showed an additive and synergistic effect with estradiol in the neurointermediate lobe on beta-endorphin synthesis.

CONCLUSIONS

Drospirenone significantly increases central and circulating beta-endorphin levels and does not seem to interfere with allopregnanolone production.

Comparison of two oral contraceptives containing either drospirenone or cyproterone acetate in the treatment of hirsutism

Combined oral contraceptives (COCs) are considered the first-line treatment for women with hirsutism. They diminish androgen release from the ovary and decrease plasma free testosterone levels by increasing sex hormone-binding globulin (SHBG) concentrations. COCs containing cyproterone acetate (CPA) and drospirenone (DRSP) have been proved effective for the treatment of acne and facial hirsutism. This study prospectively compared the clinical and biochemical efficacy of 3 mg DRSP/30 microg ethinyl estradiol (EE) and 2 mg CPA/35 microg EE combinations in a total of 91 patients with hirsutism. Individuals randomly received a cyclic combination of either DRSP/EE (n=48) or CPA/EE (n=43) for 12 months. Basal serum total testosterone, free testosterone, androstenedione, dehydroepiandrosterone sulfate and SHBG levels, as well as Ferriman-Gallwey scores, were determined before and after treatment. Both COCs achieved a similar effect on clinical hirsutism scores, in addition to serum androgen and SHBG levels, after completion of therapy. The percentage reductions in total hirsutism score (median % (min-max)) during therapy were 0.70 (0-0.58) vs. 0.57 (0.10-1.00) at 6 months (p = 0.028) and 0.80 (0-0.42) vs. 0.81 (0-0.75) at 12 months (p = 0.6) in the DRSP/EE and CPA/EE groups, respectively. In conclusion, the DRSP/EE combination is at least as effective as the CPA/EE combination in improving hirsutism scores.

Positive correlation between anxiety severity and plasma levels of dehydroepiandrosterone sulfate in medication-free patients experiencing a major episode of depression

Although numerous studies have identified a correlation between dehydroepiandrosterone sulfate (DHEAS) levels and anxiety or depression, those findings remain controversial. The purpose of the present study was to determine whether a correlation exists between depression severity and anxiety severity and serum DHEAS concentrations in medication-free patients experiencing a major depressive episode. Twenty-eight medication-free major depressive outpatients (Hamilton Rating Scale for Depression 17 [HAM-D 17] score >or=17) were enrolled consecutively. Plasma DHEAS levels of all subjects were measured. Blood from subjects was drawn at 0900-1100 h Depression severity was assessed with the HAM-D 17 and the Hospital Anxiety and Depression Scale (HADS) depression subscale. Anxiety was assessed using the HADS anxiety subscale. Serum concentrations of DHEAS were measured immediately following the HAM-D 17 and HADS assessments. A significant, positive correlation was identified between HADS anxiety subscale total score and morning serum DHEAS concentration (P = 0.013) after controlling for age, gender and body mass index (BMI). No statistically significant correlations were found between depression ratings and morning serum DHEAS concentrations. This preliminary study provides pilot data indicating that morning serum DHEAS concentrations were positively correlated with HADS anxiety subscale score (anxiety severity) after controlling for age, gender and BMI in medication-free outpatients experiencing a major depressive episode. It is not known if morning serum DHEAS levels would show similar or dissimilar changes in non-depressed subjects. The present result needs subsequent replication.

Oral contraceptives and neuroactive steroids

A deregulation in the peripheral and brain concentrations of neuroactive steroids has been found in certain pathological conditions characterized by emotional or affective disturbances, including major depression and anxiety disorders. In this article we summarize data pertaining to the modulatory effects of oral contraceptive treatment on neuroactive steroids in women and rats. Given that the neuroactive steroids concentrations are reduced by oral contraceptives, together with the evidence that a subset of women taking oral contraceptives experience negative mood symptoms, we propose the use of this pharmacological treatment as a putative model to study the role of neuroactive steroids in the etiopathology of mood disorders. Moreover, since neuroactive steroids are potent modulators of GABA(A) receptor function and plasticity, the treatment with oral contraceptives might also represent a useful experimental model to further investigate the physiological role of these steroids in the modulation of GABAergic transmission.

Observational study on the stability of the psychological status during normal pregnancy and increased blood levels of neuroactive steroids with GABA-A receptor agonist activity

We investigated whether pregnancy could modify psychological symptoms and whether neuroactive steroids which exert an anti-anxiety effect by acting on the gamma-aminobutyric acid (GABA)-A receptors, are modified during pregnancy in young healthy women. Healthy volunteer women in the Department of Obstetrics and Gynecology at Cagliari University participated in the study. They were divided into women with low (group 1, seven subjects) and high (group 2, seven subjects) psychological score by SCL-90 psychometric scale. Age, body mass index and physiological status of pregnancy did not differ between the groups. The subjects were studied before pregnancy during the follicular phase (FP), and the luteal phase (LP) of the menstrual cycle (MC) and four times during pregnancy (at 14th, 22nd, 30th, and 38th week). SCL-90 psychometric scale, circulating levels of progesterone (P4), 3alpha-hydroxy-5alpha-pregnan-20-one (allopregnanolone, AP), 3alpha,21-dihydroxy-5alpha-pregnan-20-one (allotetrahydrodeoxy-corticosterone, THDOC), cortisol and DHEAS were assayed at each visit. The SCL-90 global score and the intensity of psychological symptoms differ between the groups, but within each group they did not change both during MC and during pregnancy. The DHEAS and cortisol levels did not differ between the groups. DHEAS did not change during the study, whereas cortisol levels increased during pregnancy in both groups. Progesterone, AP, and THDOC levels were higher during LP than during FP and further increased during pregnancy, without any difference between the groups. In conclusion, pregnancy does not seem to interfere with the psychological status of healthy women independently of the psychological basal score. Some neuroactive steroids with anxiolytic activity seem to increase during pregnancy depending on placental function. Their increase could represent some kind of protection against maternal anxiety and stress due to concerns about the pregnancy outcome.

Oral contraceptives and mood in women with and without premenstrual dysphoria: a theoretical model

Despite numerous studies on the topic, there is no consensus to date on the effects of oral contraceptives on mood or the mechanism(s) by which they exert these effects. This review article presents a theoretical model to explain the way in which oral contraceptives may affect mood. Specifically, it is argued that progestins exert differential effects on endogenous levels of neurosteroids, thereby altering mood. After providing an overview of the effects of estrogen, progesterone, and progesterone's metabolites on cortical excitability and the role of neurosteroids in depression and premenstrual dysphoria, this article reviews the research that has been conducted on the relationship between oral contraceptives and neurosteroids. Finally, suggestions for future research are made with the dual aim of improving existing studies on the relationship between oral contraceptives and mood and further investigating the possibility that fluctuations in neurosteroid levels are responsible for the effects of oral contraceptives on mood.

Short-term variations in bone remodeling markers of an oral contraception formulation containing 3 mg of drospirenone plus 30 μg of ethinyl estradiol: Observational study in young postadolescent women

The clinical study of treated subjects and nontreated controls was made in healthy eumenorrheic young postadolescent women volunteers in the Department of Obstetrics and Gynaecology at Cagliari University, to investigate whether an oral contraceptive (OC) containing drospirenone (3 mg) plus ethinyl estradiol (30 microg) (DRSP+EE) can affect bone metabolism. Control group (n = 26) and OC group (n = 28) women did not differ in age, body mass index, waist-to-hip ratio and main outcome measures [urinary levels of deoxypyridinoline and pyridinoline, serum levels of osteocalcin, bone specific alkaline phosphatase (bSAP), total testosterone (total-T), sex hormone-binding globulin (SHBG), progesterone and bone mineral density (BMD) at the heel]. The control group was studied at the luteal phase (LP) during both the first and the sixth menstrual cycle; the OC group was studied during the first cycle at the LP, and on days 16-18 of the sixth cycle of DRSP+EE treatment. At the sixth cycle, in the control group, the main outcome measures did not change compared to baseline. In the OC group, deoxypyridinoline, pyridinoline, osteocalcin, bSAP, total-T and progesterone levels were reduced, whereas SHBG levels were increased. The BMD was unchanged compared to baseline. The results suggest that 6-month DRSP+EE treatment decreases bone turnover.
