The aim of this study was to analyze the effects of mid-cycle administration of Ulipristal acetate (UPA) on gene expression in endometrial biopsies taken during the receptive phase of the cycle. Fourteen healthy menstruating women were studied during 14 control non-treated and 12 treated cycles with a single dose of 30 mg UPA when follicle diameter reached 20 mm. Ovulation in both treated and control cycles was confirmed by serial determinations of serum LH, progesterone and vaginal ultrasound. An endometrial biopsy at day LH+7, in each cycle, was taken for RNA microarray and qPCR analysis or prepared for histological and immunohistochemistry studies...

Nonclassic congenital adrenal hyperplasia (NCAH) is an autosomal-recessive disorder caused by 21-hydroxylase deficiency and manifests as hirsutism and oligomenorrhea due to excess adrenal androgen and progesterone. We report a case of a woman with NCAH who showed continuous high serum progesterone levels in the follicular phase associated with impaired folliculogenesis. NCAH was diagnosed based on high 17-hydroxyprogesterone levels after rapid adrenocorticotropic hormone loading, and three heterozygous missense mutations in CYP21A2, encoding 21-hydroxylase, were identified...

The ultrasonographic measurement of cervical length with a cutoff of 15mm is currently the best method to identify a group of asymptomatic women in the general population at risk of spontaneous preterm birth, especially among asymptomatic patients with a singleton pregnancy with no history of preterm birth. Cerclage and 17 alpha-hydroxyprogesterone caproate (17OHP-C) are ineffective to reduce the risk of preterm birth among asymptomatic patients with a short cervix in midtrimester. However, vaginal progesterone (200-mg capsules of micronized progesterone or gel containing 90mg progesterone) has been demonstrated effective in 2 large randomized trials to reduce the risk of preterm birth and possibly the composite morbidity and perinatal mortality associated among asymptomatic women with a short cervix in the general population screened by ultrasound of the cervix in midtrimester...

BACKGROUND: Preterm birth is the primary cause of infant death worldwide. A short cervix in the second trimester of pregnancy is a risk factor for preterm birth. In specific patient cohorts, vaginal progesterone reduces this risk. Using 16S rRNA gene sequencing, we undertook a prospective study in women at risk of preterm birth (n = 161) to assess (1) the relationship between vaginal microbiota and cervical length in the second trimester and preterm birth risk and (2) the impact of vaginal progesterone on vaginal bacterial communities in women with a short cervix...

In France, 60,000 neonates are born preterm every year (7.4%), half of them after the spontaneous onset of labor. Among preventable risk factors of spontaneous prematurity, only cessation of smoking is associated with decreased prematurity (level of evidence [LE]1). It is therefore recommended (Grade A). Routine screening and treatment of vaginal bacteriosis is not recommended in the general population (Grade A). The only population for which vaginal progesterone is recommended is that comprising asymptomatic women with singleton pregnancies, no history of preterm delivery, and a short cervix at 16-24 weeks of gestation (Grade B)...

BACKGROUND: In Canada, the majority of HIV-positive pregnant women receive combination antiretroviral therapy that includes a ritonavir-boosted protease inhibitor to prevent mother-to-child HIV transmission. However, protease inhibitor-based combination antiretroviral therapy has been associated with increased rates of preterm, low birth weight, and small for gestational age births. Our previous experimental findings demonstrate that protease inhibitor use during pregnancy is associated with decreased progesterone levels that correlate with fetal growth, and that progesterone supplementation can improve protease inhibitor-induced fetal growth restriction...

ETHNOPHARMACOLOGICAL RELEVANCE: Saraca asoca (Roxb.) de Wilde, Ashok, is a popular traditional plant used for gynecological disorders. In India, the juice of Ashok flowers is traditionally consumed as a tonic by women in case of uterine disorders. But despite the use, its estrogenic potency is not yet evaluated and thus lacks the scientific recognition and acclaim. AIM OF THE STUDY: This study is designed to investigate the estrogenic potential of standardized ethanolic extract of Saraca asoca flowers (SAF) using ovariectomized (OVX) female albino Wistar rat model...

BACKGROUND: Clinically, once a woman has been identified as being at risk of spontaneous preterm birth (sPTB) due to a short cervical length, a decision regarding prophylactic treatment must be made. Three interventions have the potential to improve outcomes: cervical cerclage (stitch), vaginal progesterone and cervical pessary. Each has been shown to have similar benefit in reduction of sPTB, but there have been no randomised control trials (RCTs) to compare them. METHODS: This open label multi-centre UK RCT trial, will evaluate whether the three interventions are equally efficacious to prevent premature birth in women who develop a short cervix (<25 mm on transvaginal ultrasound)...

BACKGROUND: Preterm birth (PTB) is the leading cause of perinatal morbidity and mortality worldwide, and its prevention is an important health-care priority. The cervical incompetence is a well-known risk factor for PTB and its incidence is about 0.1-2.0%, while there is no ideal optimum treatment recommended currently. The cervical incompetence causes about 15% of habitual abortion in 16-28 weeks. This study aimed to evaluate the effectiveness and safety of cervical cerclage and vaginal progesterone in the treatment of cervical incompetence with/without PTB history...

Endometriosis is characterized by frequent recurrences of symptoms and lesions even after extirpative surgery. Because medical therapies control but do not cure the disease, long periods of pharmacologic management may be needed until pregnancy desire or, sometimes, physiologic menopause. Hormonal drugs suppress ovulation and menstruation and have similar beneficial effects against pain. However, only estrogen-progestins and progestins have safety/tolerability/cost profiles that allow long-term use. These compounds induce atrophy of eutopic and ectopic endometrium, have antiinflammatory and proapoptotic properties, and can be delivered via different modalities, including oral, transdermal, subcutaneous, intramuscular, vaginal, and intrauterine routes...

: Ultrasound measurement of cervical length in the general population enables the identification of women at risk for spontaneous preterm delivery. Vaginal progesterone is effective in reducing the risk of preterm delivery in this population. This screening associated with treatment by vaginal progesterone is cost-effective. Universal screening of cervical length can therefore be considered justified. Nonetheless, this screening will not appreciably reduce the preterm birth prevalence: in France or UK, where the preterm delivery rate is around 7...
