RESUMO
Background: The serum P concentrations are suggested to have an impact on pregnancy outcome. However there is no consensus about the optimal progesterone cut-off during the luteal phase. Few studies evaluated the effectiveness of a "rescue protocol" for low serum P concentrations and most of these studies used vaginal progesterone administration. There is paucity of data on the effectiveness of rescue protocol using intramuscular progesterone (IM-P) in frozen-thawed embryo transfer (FET). Methods: This study is a retrospective cohort study included 637 single or double blastocyst FETs with artificially prepared endometrium receiving 100 mg IM progesterone (P) after incremental estrogen treatment. Serum P concentrations were evaluated using blood samples obtained 117-119 hours after the first IM-P administration and 21 ± 2 hours after the last IM-P administration. Patients with serum P concentrations <20.6 ng/ml on the ET day were administrated 400 mg vaginal progesterone for rescue. Results: Demographic and cycle characteristics were similar between patients receiving rescue vaginal P (embryo transfer (ET)-day P concentration < 20.6 ng/ml) and patients who did not need rescue vaginal P (ET-day P concentration ≥ 20.6 ng/ml). Clinical pregnancy, miscarriage, and live birth rates were similar between two groups: 52.9%(45/85) vs 59.6%(326/552), p=0.287; 11.1%(5/45) vs 14.1%(46/326), p=0.583; and 47.1%(40/85) vs 50.7%(280/552), p=0.526, respectively. Logistic regression analysis revealed that the female age (p = 0.008, OR=0.942, 95% CI = 0.902-0.984) and embryo quality (ref: good quality for moderate: p=0.02, OR=0.469, 95% CI =0.269-0.760; for poor: p=0.013, OR= 0.269, 95% CI = 0.092-0.757) were independent variables for live birth. Following rescue protocol implementation, ET-day P concentration was not a significant predictor of live birth. Conclusions: Rescue vaginal P administration for low ET day serum P concentrations following IM-P yields comparable live birth rates.

This study aimed to determine whether the use of vaginal Endometrin plus intramuscular progesterone on every third day (VIM) in programmed frozen embryo transfer (FET) is associated with lower pregnancy and live birth rates compared to daily intramuscular progesterone (IM). FET data from a single program were collected between November 2018 and December 2021. A total of 903 FETs were analyzed, including 504 FETs in the IM group, and 399 FETs in the VIM group. Inclusion criteria were women undergoing FETs with either 50 mg daily IM progesterone only (control) or 200 mg Endometrin twice daily plus 50 mg IM progesterone on every third day, with the transfer of a single day 5 or 6 frozen embryo. There were no significant differences in patient age at time of FETs, BMI, endometrial thickness, blastocyst quality, or infertility diagnosis between the groups. The VIM had significantly lower positive hCG and clinical pregnancy rates compared to the IM (60.2% vs 72.0% and 40.6% vs 56.7%, respectively, P = 0.0002 and P < 0.0001). The live birth rate was 36.1% in the VIM, compared to 49.4% in the IM (P < 0.0001). These findings also remained significant when excluding FETs with donor egg (35.9% vs 50.1%, P < 0.0001). This study demonstrated that VIM in FET cycles yields significantly lower pregnancy and live birth rates compared to IM along. IM progesterone alone may be preferable to combined Endometrin and IM progesterone in patients undergoing programmed frozen embryo transfers.
RESUMO
Progesterone hypersensitivity (PH) is a rare hypersensitivity reaction to either endogenous or exogenous progesterone. There are around 200 reported cases of progesterone hypersensitivity in the medical literature. We present the case of a 31-year-old female who presented with cyclical urticaria and angioedema after exogenous progesterone exposure. Her symptoms would begin a few days before her menstrual cycle began and resolve after menstruation. She only had partial recovery of her symptoms with antihistamines, steroids, montelukast, and omalizumab. She needed treatment with oral contraceptives and had a resolution of symptoms, but subsequently developed a recurrence again. Given the rarity of this condition, the diagnosis is often delayed. This diagnosis should be considered for women of reproductive age who present with cyclic hypersensitivity or allergic symptoms.
RESUMO
Objective: To compare the ongoing pregnancy rates (OPRs) for subcutaneous progesterone (SC-P) to intramuscular progesterone (IM-P) in hormone replacement therapy used in frozen embryo transfer (FET) cycles. Design: Prospective nonrandomized cohort study. Setting: Private fertility clinic. Patients: The study enrolled 224 patients scheduled for hormone replacement therapy (HRT)-FET cycles with SC-P (n = 133) or IM-P (n = 91). The route of P administration was decided according to the patient's preference and accessibility to the hospital. In the first FET cycle of a freeze-all cycle using single blastocyst transfers, a woman aged ≤35 was included. Main Outcomes: Ongoing pregnancy (OP). Results: The demographic, cycle, and embryologic characteristics were similar between groups. The clinical pregnancy rates (86/133[64.7%] vs. 57/91[62.6%]); miscarriage rates (21/86 [24.4%] vs. 10/57 [17.5%]), and OPR (65/133 [48.9%] vs. 47/91 [51.6%]) were comparable between the SC-P and IM-P groups. Binary logistic regression for OP as the dependent factor revealed that blastocyst morphology was found to be a significant independent prognosticator (for poor quality embryos adjusted odds ratio, 0.11; 95% confidence interval, 0.029-0.427) and progesterone route (SC-P vs. IM-P) was an insignificant prognosticator (adjusted odds ratio, 0.694; 95% confidence interval, 0.354-1.358). Conclusions: The OPR for SC-P administration was similar to that for IM-P in HRT-FET cycles. The effect of ET-day P levels may vary regarding the administration route. Randomized controlled trials comparing different P administration routes are needed, and large-scale prospective trials are warranted to evaluate the ET-day P levels on pregnancy outcome.
RESUMO
PURPOSE: The purpose of this study was to identify if switching from intramuscular (IM) to vaginal progesterone compared to staying on IM progesterone after a positive pregnancy test following embryo transfer (ET) is associated with miscarriage risk. METHODS: A retrospective cohort study was performed in a private university-affiliated fertility clinic and included women aged 18-50 years with a positive pregnancy test following ET. The two groups studied were: women who stayed on IM progesterone following a positive pregnancy test and those who switched to vaginal progesterone after a positive test. The main outcome measured was risk of miscarriage < 24 weeks gestation as a proportion of non-biochemical pregnancies. RESULTS: 1988 women were included in the analysis. Among the baseline characteristics, the presence of prior miscarriages as well as prior failed ETs, and frozen cycles (vs fresh) as type of transfer were associated with IM progesterone use (p values ≤ 0.01). As per miscarriage risk < 24 weeks, 22.4% (274/1221) of patients in the IM progesterone group experienced a miscarriage compared with 20.7% (159/767) in the vaginal progesterone group (OR 0.90; 95% CI 0.73-1.13). A multivariable logistic regression model revealed an adjusted OR (aOR) of 0.97 (95% CI 0.77-1.22). CONCLUSION: This study suggests that switching from IM to vaginal progesterone after a positive pregnancy test following an ET is not associated with miscarriage risk. Considering that IM progesterone imposes substantial discomfort, this study offers reassurance and some flexibility in treatment protocols. Further prospective studies are necessary to corroborate the results of this study.

Objective: The need of luteal support after FET is no longer to be proven. Different routes of progesterone administration are available with interindividual differences in metabolization and serum progesterone levels, the latter being highly correlated with pregnancy and delivery rates. The administration of 2 different routes of progestogen significantly improves success rates in FET. The aim of the current study was to investigate the added value to combine intramuscular administration of progesterone to dydrogesterone in fresh embryo transfer. Methods: This is a retrospective study from prospectively collected data. Patient, aged between 18 and 43 years old, had received a fresh blastocyst transfer between January 2021 and June 2021. In the first group, all patients received only oral dydrogesterone 10mg, three times a day, beginning the evening of oocyte retrieval. In the second group, patients received, in addition to dydrogesterone, a weekly intramuscular injection of progesterone started the day of embryo transfer. Primary endpoint was ongoing pregnancy rate. Results: 171 fresh single blastocyst transfers have been performed during this period. 82 patients were included in "dydrogesterone only" and 89 patients in "dydrogesterone + IM". Our two groups were comparable except for body mass index. After adjustment on BMI, our two groups were comparable regarding implantation rate, early pregnancy rate (46.1 versus 54.9, OR 1.44 [0.78; 2.67], p=0.25) miscarriage rate, ongoing pregnancy rate (30.3 versus 43.9, OR 1.85 [0.97; 3.53] p= 0.06). Conclusion: Using systematically long acting intramuscular progesterone injection in addition to oral dydrogesterone as luteal phase support seems to have no significant impact on IVF outcomes when a single fresh blastocyst transfer is performed.

OBJECTIVE: To compare pregnancy outcomes in patients undergoing artificial reproductive treatment (ART) and fresh embryo transfer (ET) who received twice-daily vaginal progesterone capsule (Cyclogest) alone verses twice daily vaginal progesterone capsule (Cyclogest) plus weekly intramuscular Hydroxyprogesterone Capronate (Proluton depot) for luteal phase support. METHODS: A retrospective cohort study that included 1162 patients who completed fresh ART/ET cycle from January 2015 to April 2018. Vaginal Cyclogest 400 mg twice daily was given to 985 patients following oocytes retrieval; whereas 177 patients received weekly intramuscular Proluton depot 250 mg in addition to twice-daily Cyclogest. The primary outcome was live birth rate. The secondary outcomes included biochemical pregnancy rate, clinical pregnancy, biochemical, and early and late pregnancy loss. RESULTS: There was no difference between the twice-daily vaginal progesterone and the addition of weekly intramuscular progesterone injections to the twice-daily vaginal progesterone regarding a positive pregnancy test (40.5% and 46.9%, respectively, p=0.112). There was no statistical difference in live birth rates between the groups (24% for group one, 26% for group two, p=0.582). CONCLUSIONS: The administration of weekly intramuscular progesterone in addition to twice-daily vaginal progesterone capsule for luteal phase support post ART cycle does not result in higher live birth rate.

BACKGROUND: It remains under subject of debate regarding the optimal route of luteal support for hormone replacement therapy- frozen embryo transfer (HRT-FET) cycles. We compared efficacy of vaginal progesterone gel combined with oral dydrogesterone and intramuscular progesterone for HRT-FET lutein support. METHODS: This is a retrospective observational study. After matching for propensity score of getting vaginal + oral treatment, a total of 208 FET cycles in the vaginal progesterone combined with oral dydrogesterone and 624 cycles in the intramuscular progesterone group were enrolled. Pregnancy outcomes and neonatal outcomes including chemical pregnancy rate, clinical pregnancy rate, implantation rate, spontaneous abortion rate, live birth rate, gestational weeks, pre-term delivery, birth weight, and congenital anomalies rate were compared. RESULTS: No significant differences were observed in patient characteristics such as age, duration of infertility, type of infertility, or hormone level after matching. Chemical pregnancy rate (68.3 % versus 70.5 %), clinical pregnancy rate (64.9 % versus 64.4 %), implantation rate (52.3 % versus 50.2 %), spontaneous abortion rate (21.5 % versus 18.4 %), and live birth rate (49.0 % versus 51.3 %) were similar in both group without statistically significant difference. No significant differences in neonatal outcomes were observed between the two groups. CONCLUSION: We observed similar pregnancy outcomes in both vaginal progesterone gel combined with oral dydrogesterone and intramuscular progesterone protocol. Vaginal progesterone gel combined with oral dydrogesterone can be substituted for intramuscular progesterone given that vaginal plus oral use has good safety and is more convenient and may be associated with less side effect caused by intramuscular injection.

AIM: This study was performed to evaluate the effects of vaginal versus intramuscular progesterone supplementations on the mood, quality of life, and metabolic changes in pregnant women with the history of previous preterm birth. METHODS: This study was conducted as a prospective, randomized, open label, clinical trial evaluated 100 pregnant women who referred for prenatal visit, with 16-17 weeks of gestation from September 2014 through October 2015. The mothers were then randomly allocated into two groups: the vaginal progesterone group to receive 400 mg cyclogest vaginal suppositories (Actavis, UK limited, England) once daily, and the intramuscular progesterone group to receive weekly intramuscular injections of 250 mg of 17-hydroxyprogesterone caproate (17-HPC) (Bayer Schering Pharma, Germany), starting from the 16th to the 35th weeks of pregnancy. Demographics, medical and obstetrical history, sleeping disturbances, alteration in sexual desire, nausea/vomiting, serum levels of fasting blood sugar (FBS), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were evaluated, first and 8 weeks later. RESULTS: About 11 (11.2%) screened positive for psychosocial disorders; 25 (25.5%) had sleep disturbance, 11 (11.2%) had alteration in sexual desire, and 29 (29.6%) had nausea/vomiting upon enrollment. After 2 months of receiving daily vaginal progesterone, there was a significant increase in the GHQ-28 score (p < .001), and rates of positive screening for psychosocial disorders (p = .001) in this group. No statistically significant differences were observed in the HDL levels (p = .06), LDL levels (p = .15), rates of impaired FBS (p = .08), nausea/vomiting (p = .2), sexual desire alteration (p = .56), and sleep disturbance (p = 1) in the participants who were randomized to this group. CONCLUSION: Our results indicated that psychosocial disorders increased significantly at 24th week gestational age after 2 months of progesterone consumption in both groups which could show psychological impact of progesterone regardless of the route of consumption. This calls for higher psychological attention in these women.

OBJECTIVE: Cryopreservation of embryos for future transfer attempts has noticeably increased in the last decade, especially due to the technological developments in in vitro fertlization (IVF) laboratories. In parallel, different progesterone (P) replacement regimens preceding artificially prepared frozen embryo transfer (AC-FET) attempts, especially with respect to the route of application and dosing scheme, have been widely argued so far. We aimed to provide more information about the efficacy profile of novel subcutaneous aqueous progesterone (SP) in AC-FET cycles. MATERIALS AND METHODS: This retrospective, single-centre cohort study included a total of 507 AC-FET cycles performed between June 2018 and April 2020. Three hundred forty-nine (68.8%) patients received 50 mg of intramuscular progesterone as once daily, 158 (31.2%) patients received 25 mg of SP as twice daily. Only, the first and single blastocyst transfers from the same cohort were accepted. The inclusion criteria were as follows: females aged <37 years, body mass index ≥18 kg/m2 and ≤35 kg/m2, sperm concentration ≥5x106/mL. Pre-implantation genetic testing cycles were not included. The primary outcome was the live birth rate (LBR). RESULTS: The number of previous IVF attempts, type of infertility, peak estradiol (E2) levels, the total number of retrieved oocytes, mature oocytes, and the number of 2PN was significantly different between the groups. Positive pregnancy (p=0.474) and clinical pregnancy rates (p=0.979), LBR (p=0.404), and missed abortion rates (p=0.144) were comparable between the groups. The total number of oocytes [adjusted odds ratios (AOR)=1.024, 95% confidence interval (CI): 1.002-1.047; p=0.03)], endometrial thickness (AOR=1.121, 95% CI: 1.003-1.253; p=0.044), and cryopreservation day 5/6 (AOR=0.421, 95% CI: 0.226-0.788; p=0.007) achieved statistical significance following binary logistic regression analysis. However, P administration type did not achieve statistical significance (p=0.731). CONCLUSION: As a novel option, SP has comparable efficacy in pregnancy outcomes and may be accepted as an alternative for luteal phase support in AC-FET cycles.
RESUMO
BACKGROUND: The optimal route of progesterone administration for luteal support in cryopreserved embryo transfer (CET) has been the subject of much debate. While most published research has pertained to day 3 transfers, recent data on blastocyst CET has suggested that intramuscular progesterone (IMP) is superior to twice daily vaginal Endometrin suppositories for luteal phase support, resulting in significantly higher ongoing pregnancy rates. This study aimed to determine whether IMP is similarly superior to 8% Crinone vaginal gel for luteal phase support following blastocyst CET. METHODS: Autologous and donor oocyte blastocyst cryopreserved single embryo transfer (SET) cycles from January 2014-January 2019 utilizing either 50 mg IMP daily or 90 mg 8% Crinone gel twice daily for luteal support were included. The primary outcome was live birth. Secondary outcomes included biochemical pregnancy, spontaneous abortion, and clinical pregnancy. All analyses were adjusted a priori for oocyte age. Log-binomial regression analysis was performed with differences in outcomes reported as relative risk (RR) with 95% confidence intervals (CI). RESULTS: A total of 1710 cycles were included, of which 1594 utilized IMP and 116 utilized 8% Crinone gel. Demographic and cycles characteristics were similar between the two groups. Compared to cycles utilizing IMP, cycles utilizing Crinone gel resulted in similar rates of live birth (RR 0.91; 95% CI 0.73-1.13), biochemical pregnancy (RR 1.12, 95% CI 0.65-1.92), spontaneous abortion (RR 1.41, 95% CI 0.90-2.20), and clinical pregnancy (RR 1.00, 95% CI 0.86-1.17). CONCLUSIONS: Compared to cryopreserved blastocyst SET cycles utilizing IMP for luteal support, cycles utilizing 8% Crinone gel resulted in similar likelihood of live birth.
RESUMO
BACKGROUND: Preterm birth causes an increased risk for perinatal morbidity and mortality. OBJECTIVE: To determine whether mid-trimester 17-alpha-hydroxyprogesterone caproate (17-OHPC) reduces the risk of recurrent preterm birth and adverse perinatal outcomes. SEARCH STRATEGY: Systematic search to identify relevant studies published in different languages, registered after 2000, using appropriate MeSH terms. SELECTION CRITERIA: Inclusion criteria were women between 16 and 26+6 weeks of pregnancy with history of preterm delivery in any pregnancy randomized to either 17-OHPC or placebo/no treatment. DATA COLLECTION AND ANALYSIS: The number of preterm births and adverse outcomes in the 17-OHPC and placebo arms over the total number of patients in each randomized group were used to calculate the risk ratio (RR) by random-effects models using the Mantel-Haenszel method. Between-study heterogeneity was assessed using tau2 , χ2 (Cochrane Q), and I2 statistics. MAIN RESULTS: Four studies were included. There was a 29% (RR 0.71; 95% CI, 0.53-0.96; P=0.001), 26% (RR 0.74; 95% CI, 0.58-0.96; P=0.021), and 40% (RR 0.60; 95% CI, 0.42-0.85; P=0.004) reduction in recurrent preterm birth at <37, <35, and <32 weeks, respectively, in the 17-OHPC group compared with placebo. The reduction in neonatal death was 68% (RR 0.32; 95% CI, 0.15-0.66; P=0.002). CONCLUSIONS: 17-OHPC could reduce the risk of recurrent preterm birth at <37, <35, and <28 weeks and neonatal death. PROSPERO: CDR42017082190.

RESEARCH QUESTION: To determine whether adding intramuscular to vaginal administration of progesterone reduces miscarriage rates compared with those of vaginal administration alone for luteal phase support in women receiving oocyte donation and to determine the best time to introduce intramuscular progesterone. DESIGN: Retrospective analysis of miscarriage rates in women receiving oocyte donation. Recipients underwent endometrial preparation by hormone replacement treatment. Vaginal progesterone alone or associated with intramuscular progesterone was used for luteal support. RESULTS: This study analysed 186 oocyte donation cycles from January 2016 to May 2018 with embryo transfer on Day 2 or 3 and vaginal progesterone administration: 106 embryo transfer cycles with vaginal progesterone alone, 29 with weekly intramuscular progesterone added once the human chorionic gonadotrophin (HCG) assay was positive, and 51 with weekly intramuscular progesterone added the evening of embryo transfer. The rates of positive HCG assays, biochemical pregnancies and clinical pregnancies did not differ between the treatment groups. The miscarriage rate was significantly lower when intramuscular progesterone began the evening of embryo transfer than with vaginal administration alone (16.7% versus 47.0%, respectively; Pâ¯=â¯0.049 after Bonferroni correction). The live birth rate was higher when intramuscular progesterone began the evening of embryo transfer than with vaginal administration alone (37.3% versus 16.0%, respectively; Pâ¯=â¯0.009 after Bonferroni correction). CONCLUSIONS: Adding intramuscular to vaginal progesterone administration appears to decrease the miscarriage rate and increase the live birth rate in oocyte donations. The initiation of intramuscular progesterone is most beneficial when it is introduced the evening of embryo transfer.

PURPOSE: To compare outcomes between daily intramuscular progesterone (IMP) and daily vaginal progesterone (VP) gel plus weekly intramuscular hydroxyprogesterone caproate (IMHPC) for luteal phase support (LPS) in single, autologous euploid frozen-thawed blastocyst transfers (FBTs) following artificial endometrial preparation (EP). METHODS: The retrospective cohort study included 767 single, autologous FBTs from 731 patients between January 2015 and March 2018. LPS was performed either with IMP (100 mg/day) or with VP gel (90 mg, twice daily) plus IMHPC (250 mg/week). Oral estrogen was prescribed in combination of both regimes. Oral estrogen was discontinued following the visualization of fetal cardiac activity on ultrasound and progesterone at 10 weeks of gestation. The primary outcome was live birth rate. The secondary outcomes included implantation, clinical pregnancy, and multiple pregnancy rates. RESULTS: Patient characteristics did not differ in LPS regimes. Of 767 FBTs, 608 had IMP (100 mg/day) for LPS and 159 had VP gel (90 mg, twice daily) plus IMHPC (250 mg/week) for LPS. The live birth rate was 51.8% and 50.3%, respectively (p = 0.737, OR 0.94, 95%CI 0.66-1.33). The implantation rate was 62.7% and 64.2%, respectively (p = 0.730, OR 1.06, 95%CI 0.74-1.53). The clinical pregnancy rates were also similar in both groups (59.5% vs. 61.6%, respectively, p = 0.631, OR 1.09, 95%CI 0.76-1.56). CONCLUSIONS: We did not observe significant differences in the rates of live birth, implantation, and clinical pregnancy between daily IMP and daily VP gel plus weekly IMHPC for LPS in single, autologous euploid FBTs after artificial EP.

BACKGROUND: Luteal support is a key to patients undergoing in vitro fertilization and embryo transfer (IVF-ET) with gonadotropin-releasing hormone (GnRH)-antagonist protocol. This study aimed to compare the effect between vaginal progesterone (VP) and intramuscular progesterone (IMP) with GnRH-antagonist protocol after IVF-ET. METHODS: A total of 1760 patients (18 years ≤ age ≤35 years) undergoing IVF-ET with GnRH-antagonist protocol were studied retrospectively between September 2014 and August 2015 in Peking University Third Hospital. In the patients, 1341 patients received VP (VP group) and 419 patients received IMP (IMP group) as luteal support. We compared clinical outcomes between these two groups. The primary objective of the study was the live birth rate. Measurement data between the two groups were conducted using independent samples t-test. The variables in line with non-normal distribution were expressed as median (p25 and p75) and were compared using nonparametric Mann-Whitney U-test. RESULTS: Live birth rate in VP group was 38.55%, significantly higher than that in the IMP group, which was 30.79% (χ2 = 8.287, P = 0.004). The clinical intrauterine pregnancy rate and implantation rate in VP group were also significantly higher than those in the IMP group (clinical intrauterine pregnancy rate 47.35% vs. 41.29%, χ2 = 4.727, P = 0.030; implantation rate 30.99% vs. 25.26%, χ2 = 14.546, P < 0.001). Any statistically significant differences in ectopic pregnancy and abortion rates between two groups were not observed. CONCLUSION: : Luteal support with VP had better clinical outcomes for young women undergoing IVF-ET with GnRH-antagonist protocol.

OBJECTIVE: To evaluate outcomes among pregnancies with cerclage as compared to cerclage and adjunctive progesterone. METHODS: A retrospective cohort study was performed from 1 October 2011-30 June 2015 including women with a singleton gestation with vaginal cerclage. Exclusion criteria included multiple gestations, simultaneous 17-alpha hydroxyprogesterone caproate (17-OHPC) and vaginal progesterone (vag-p) use, and patients lost to follow-up. Primary outcome was prevention of preterm birth less than 35 (PTB <35) weeks gestational age (GA). RESULTS: One hundred thirty-six patients met inclusion criteria; 73 women had cerclage only, 53 had cerclage and 17-OHPC, 10 had cerclage and vag-p. GA at cerclage placement was similar across groups (p = 0.068). There was a difference in prevention of PTB <35 weeks GA among groups (p = 0.035) with a trend toward earlier delivery among patients with cerclage and vag-p. Rates of PTB <35 weeks in the cerclage (29%) and cerclage and 17-OHPC groups (34%) were similar (p = 0.533). The odds ratio for risk of PTB <35 weeks among women with cerclage and vag-p as compared to all other patients was 5.21 (95%CI: 1.3-21.2). CONCLUSION: The combination of cerclage with intramuscular progesterone resulted in similar PTB prevention as compared to cerclage alone. There may be an association between cerclage, vaginal progesterone and higher rates of PTB which may be attributed to characteristics of the group rather than the therapies studied.
