ABSTRACT

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.

ABSTRACT

BACKGROUND: Hysteroscopy requires accurate collection of unabsorbed distension media to measure patient fluid absorption. We assessed the effectiveness and usability of a novel total capture drape compared with a standard drape during hysteroscopy. METHOD: Simulation trials were followed by an early-phase study to compare fluid-capture efficiency and measures of drape usability during hysteroscopy randomizing the total capture drape compared with a standard drape. EXPERIENCE: Simulation trials indicated complete collection of unabsorbed fluid with the total capture drape and progressive loss of unabsorbed fluid with the standard drape. An early-phase study with 68 women found no statistical difference between groups for the hysteroscopic fluid deficit, but saw fewer cases with lost fluid in the total capture drape compared with the standard drape. Direct observation and focus group data indicated a trend for better capture of unabsorbed fluid with the total capture drape, along with increased usability once surgeons became familiar with correct placement. CONCLUSION: Simulation and early-phase study results are favorable for the total capture drape, demonstrating comparable fluid collection with the standard drape. With repeated use and in-service training, surgeons expressed greater confidence in the accuracy of the hysteroscopic fluid deficit with the total capture drape compared with the standard drape. Design modifications should improve overall usability and fluid-capture efficiency.

ABSTRACT

PURPOSE: Fatty acids have been shown to play an important role in oocyte competence and early implantation of the embryo. Our hypothesis-generating study sought to determine if individual fatty acids expressed as a percentage of total erythrocyte fatty acids are associated with embryo quality and other in vitro fertilization (IVF) outcomes. METHODS: This was a prospective cohort study at an academic fertility center. Sixty women undergoing their first IVF cycle were recruited. Serum measurements of 22 fatty acids were obtained. We calculated each fatty acid as a percentage of total fatty acids, defined as the index for that individual fatty acid. RESULTS: Omega-3 index had no correlation with IVF outcomes. A negative correlation was found between the trans fatty acid index, elaidic acid (EA), and IVF outcomes, including fertilization rate (r = - 0.261, p = 0.04), blastocyst conversion rate (r = - 0.41, p = 0.001), and number of usable blastocysts and embryos (r = - 0.411, p = 0.001). There was no correlation between EA index and number of oocytes retrieved, embryo grade, or clinical pregnancy. No consistent correlations were observed with the additional fatty acids analyzed. CONCLUSIONS: No correlation was observed between omega-3 index and IVF outcomes. Elevated erythrocyte EA index, the major trans fatty acid commonly consumed in hydrogenated oils, margarine, and fried foods, was negatively correlated with number of usable blastocysts and embryos, blastocyst conversion, and fertilization rate. Our findings suggest preliminary evidence that trans fat may be negatively associated with IVF outcomes.

ABSTRACT

PURPOSE: Hematopoietic stem cell transplantation (HSCT) is a cure for sickle cell disease (SCD) but frequently results in permanent sterility. The complications associated with oocyte cryopreservation and risks of future pregnancy are increased in SCD patients. This case report discusses risk reduction strategies and includes a literature review of pregnancy after HSCT. CASE: A 23-year-old woman underwent ovarian stimulation for fertility preservation resulting in cancelation due to acute pain crisis. She underwent a successful oocyte retrieval after exchange transfusion to decrease her hemoglobin S to 30%. This is the second report of a pain crisis in a woman with SCD undergoing oocyte banking. CONCLUSION(S): Women with SCD undergoing fertility preservation may be at increased risk of complications from ovarian stimulation. Risks in pregnancy after HSCT should also be considered before proceeding with fertility preservation.

ABSTRACT

Abnormal uterine bleeding is a common medical condition with several causes. The International Federation of Gynecology and Obstetrics published guidelines in 2011 to develop universally accepted nomenclature and a classification system. In addition, the American College of Obstetrics and Gynecology recently updated recommendations on evaluation of abnormal uterine bleeding and indications for endometrial biopsies. This article reviews both medical and surgical treatments, including meta-analysis reviews of the most effective treatment options.

ABSTRACT

Objective. To determine if sexual intercourse reduces absorption of vaginal progesterone gel in women and to determine if progesterone is absorbed by the male during intercourse. Study Design. Prospective, randomized, cross over, controlled study of 20 reproductive-aged women and their male sexual partners randomized to receive vaginal progesterone gel (Crinone 8% gel, Actavis Inc., USA) or placebo cream. Serum progesterone for both male and female partners were measured 10 hours after intercourse. One week later, subjects were crossed over to receive the opposite formulation. In the third week, women used progesterone gel at night and abstained from intercourse. Results. Serum progesterone was significantly reduced with vaginal progesterone gel + intercourse compared with vaginal progesterone gel + abstinence (P = 0.0075). Men absorbed significant progesterone during intercourse with a female partner using vaginal progesterone gel compared to placebo (P = 0.0008). Conclusion(s). Vaginal progesterone gel is reduced in women after intercourse which may decrease drug efficacy during luteal phase support. Because men absorb low levels of progesterone during intercourse, exposure could cause adverse effects such as decreased libido. This study is registered under Clinical Trial number NCT01959464.

ABSTRACT

OBJECTIVE: To determine whether the period of ejaculatory abstinence (EA) influences the total antioxidant capacity (TAC) of semen or lipid peroxidation (LPO) of sperm membranes. DESIGN: A prospective experimental trial. SETTING: Academic medical center for reproductive endocrinology and infertility. PATIENT(S): Forty men from infertile couples planning intrauterine insemination. INTERVENTION(S): Men provided semen specimens after EA periods of 1 and 4 days. MAIN OUTCOME MEASURE(S): Semen analysis, peroxidase staining, and assays for seminal TAC and sperm membrane LPO, with measures compared between days 1 and 4 within individuals (internal control) using paired t tests. RESULT(S): The shorter period of EA (1 day vs. 4 days) resulted in statistically significant decreases in semen volume (-24%), sperm density (-28%), and total sperm count (-3.2%). There was a statistically significant increase in TAC with the shorter period of EA (1 day) compared with 4 days of EA. No difference was detected in sperm membrane LPO comparing 1 day of EA and 4 days of EA. CONCLUSION(S): Higher seminal TAC obtained after a shorter period of EA could diminish oxidative stress-induced sperm damage by a mechanism independent of LPO. Shorter periods of EA may thus improve sperm quality by protecting from reactive oxygen species damage, even though lower numbers of motile sperm are produced after a shorter period of EA. This would be consistent with prior research indicating improved results after intrauterine insemination under these circumstances.

ABSTRACT

OBJECTIVE: To determine how often women with Ehlers-Danlos syndrome experience obstetric and gynecologic issues both compared with the general population and within the three most common subtypes of Ehlers-Danlos syndrome. METHODS: An anonymous, prospective, online questionnaire in English was posted to the Ehlers-Danlos National Foundation web site (http://ednf.org). RESULTS: Of the 1,769 of those who completed the survey, 1,225 reported a typed diagnosis of Ehlers-Danlos syndrome. Further stratification to the three most common types and reproductive-aged women (n=775) allowed conclusions to be made about differences in rates of obstetric complications and gynecologic dysfunction compared with the general population and between types of Ehlers-Danlos syndrome. Rates of obstetric outcomes for women who reported at least one pregnancy included term pregnancy in 69.7%, preterm birth in 25.2%, spontaneous abortion in 57.2%, and ectopic pregnancy in 5.1%. Infertility was reported by 44.1% of survey respondents. Normal menstrual cycles were reported by only 32.8% with intermenstrual bleeding occurring in 18.6%. Heavy menstrual bleeding was reported by 32.9% survey participants. Gynecologic pain reported included dysmenorrhea by 92.5% and dyspareunia by 77.0%. CONCLUSION: There is a much greater prevalence of obstetric and gynecologic issues reported by women with Ehlers-Danlos syndrome than in the general population. Additionally, rates differed significantly among the three most common types of Ehlers-Danlos syndrome with vascular type having the highest rates of adverse pregnancy outcomes and menstrual abnormalities. Physician providers should be aware of these challenges and should counsel patients with Ehlers-Danlos syndrome about relevant options and risks.

ABSTRACT

OBJECTIVE: To assess whether blood type was associated with diminished ovarian reserve (DOR) (day-3 follicle-stimulating hormone level >10 IU/L), controlling for history of tobacco smoking, body mass index (BMI), history of endometriosis, ovarian surgery, previous pregnancy, and maternal age. DESIGN: Cross-sectional study. SETTING: Academic medical center, Division of Reproductive Endocrinology and Infertility. PATIENT(S): Women undergoing in vitro fertilization (IVF) from 2006-2011 (n = 305). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Presence of DOR in relation to a patient's blood type. RESULT(S): Other investigators have reported an increased risk for DOR in patients with blood type O and a protective effect on ovarian reserve for blood type A. We observed no association between a woman's blood type and DOR. We found an increased risk for DOR in patients aged 35 and older. Obesity (BMI ≥ 30 vs. BMI <25) was associated with lower odds of DOR. CONCLUSION(S): In comparison with blood type A, blood type O is not associated with an increase in DOR. We found no clinical implications for using blood type as a risk factor for DOR.

ABSTRACT

Oncofertility is an exciting new interdisciplinary field that encompasses the obstetrician gynecologist, gynecologic oncologist, reproductive endocrinologist, and primary care physician in a common goal to provide fertility preservation options for cancer patients. Maintaining their fertility is of the upmost importance for many oncology patients diagnosed during their childbearing years. This review addresses the common types of cancers in reproductive-age patients and how the treatment of these cancers may impact reproductive potential. Fertility preservation treatments will also be discussed to assist health care providers in appropriately counseling patients about options after a diagnosis of cancer. The goal of oncofertility is to provide both physicians and patients with the knowledge and resources to make fertility an ongoing opportunity for all patients who desire a future with children.

ABSTRACT

OBJECTIVE: To study the effect of ketorolac, a potent anti-inflammatory medication, on in vitro fertilization (IVF) pregnancy outcomes when used at the time of oocyte retrieval. DESIGN: Retrospective review of 454 patients from 2003-2009. SETTING: Tertiary hospital-affiliated fertility center. PATIENT(S): Consecutive subfertile women undergoing their first IVF cycle. INTERVENTION(S): Ketorolac administration immediately after oocyte retrieval. MAIN OUTCOME MEASURE(S): Pregnancy, implantation, live-birth, and miscarriage rates, and postsurgical visual analog pain score. RESULT(S): Of the 454 patients undergoing their first IVF cycle for all indications, 103 received intravenous ketorolac immediately after oocyte retrieval, based on anesthesiologist preference. Patient and procedural characteristics were similar between both groups. The use of ketorolac had no effect on the rates of implantation, miscarriage, pregnancy, live birth, or multiple pregnancy. The patients receiving ketorolac experienced statistically significantly less pain. CONCLUSION(S): This study suggests ketorolac has no apparent detrimental effect on IVF pregnancy outcomes when administered immediately after oocyte retrieval. Ketorolac appears to be a safe and effective analgesic to use at the time of oocyte retrieval.

ABSTRACT

Given the increases in 5-year cancer survival and recent advances in fertility preserving technologies, an increasing number of women with cancer are presenting for discussion of fertility preserving options. This review will summarize the risk of infertility secondary to cancer treatment, available treatment options for fertility preservation, and techniques to reduce future risks for patients. Concerns that will be addressed include the risk of the medications and procedures, the potential delay in cancer treatment, likelihood of pregnancy complications, as well as the impact of future pregnancy on the recurrence risk of cancer. Recent advances in oocyte cryopreservation and ovarian stimulation protocols will be discussed. Healthcare providers need to be informed of available treatment options including the risks, advantages, and disadvantages of fertility preserving options to properly counsel patients.

ABSTRACT

OBJECTIVE: The objective of the study was to determine the efficacy of a novel "stair-step" clomiphene protocol in women with polycystic ovarian syndrome (PCOS) who do not respond to 50 mg clomiphene. STUDY DESIGN: This was a retrospective analysis at an academic fertility center. The stair-step protocol is performed as follows: 50 mg clomiphene for 5 days, ultrasonography on days 11-14. If unresponsive, immediately begin 100 mg clomiphene for 5 days and repeat ultrasound in 1 week. If still unresponsive, begin 150 mg clomiphene for 5 days and repeat the ultrasound in 1 week. Stair-step cycles were compared with published historical clomiphene outcomes for women who were nonresponsive. RESULTS: The time to ovulation was 32-53 days less with the stair-step protocol compared with a traditional regimen. The dose-dependent ovulation rate was 64% at 100 mg with the stair-step protocol compared with 22% with a traditional regimen. CONCLUSION: It is not necessary to induce menses before increasing clomiphene doses in nonresponsive PCOS patients.

ABSTRACT

OBJECTIVE: To determine if intercourse changed serum estradiol levels in women using vaginal E2 cream or in their male partners. STUDY DESIGN: Prospective, randomized, placebo-controlled, crossover, blinded study of 10 postmenopausal women and their male sexual partners. Subjects were randomized to estradiol or placebo cream and intercourse, then crossed over after 7-14 days. Seven to 14 days later, the woman used vaginal estradiol cream and abstained from intercourse. Serum E2 levels were obtained 10-12 hours after each exposure. RESULTS: Serum E2 levels were higher in 8 of 10 men after intercourse with vaginal estradiol cream, and this resulted in a small but significant (p = 0.03) increase in the estradiol levels as compared to placebo. Paradoxically, intercourse resulted in markedly lower estradiol levels in women as compared to abstinence (p = 0.004). CONCLUSION: Men absorb vaginal estradiol during intercourse, whereas intercourse reduces estradiol absorption in women. Although serum estradiol levels were only mildly elevated in men, it is possible that long-term exposure could cause feminizing changes. In women, estradiol levels were markedly reduced by intercourse.

ABSTRACT

The ultimate goal is to develop a safe vaginal ultrasound-directed myolysis needle to treat uterine myomas. The specific preclinical study objective was to determine the optimal power to coagulate myomas in hysterectomy specimens with a prototype needle in a prospective preclinical study with an echogenic insulated needle electrode. In phase I of the study, myolysis was performed with ultrasound guidance at various powers and times. In phase II, a 20-W coagulating current was applied at defined distances from the serosa and surface temperatures measured. Myolysis with 10 to 20 W applied 5 to 10 seconds was optimal, because tissue popping occurred at 30 W or more when the needle was 5 mm or less from the serosa. The serosal temperature was never elevated above physiological ranges at any distance at this setting. Ultrasound-directed transvaginal myolysis may provide another option for women with uterine myomas if it is proven safe and effective in future clinical studies. On the basis of the observations in these preclinical studies, myolysis with 20 W for 10 seconds should be a safe parameter for clinical research, because there is no increased serosal temperature at these settings.

ABSTRACT

OBJECTIVE: To present a case of selective arterial embolization for the treatment of placenta increta in a patient with subsequent pregnancy. DESIGN: Case report and literature review. SETTING: Community-based hospital. PATIENT(S): A 31-year-old G2P1 woman with placenta increta presenting with delayed postpartum hemorrhage. INTERVENTION(S): Selective uterine artery embolization. MAIN OUTCOME MEASURE(S): Cessation of uterine hemorrhage, future pregnancy. RESULT(S): The patient's uterine bleeding immediately resolved. She subsequently delivered a healthy neonate at term without recurrence of abnormal placentation. CONCLUSION(S): Arterial embolization is effective for treating placenta increta in women who wish to preserve fertility. A review of the literature demonstrates a 76.9% success rate and an 11% complication rate.

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the effects of 2 different call schedules on post-call cognitive function and satisfaction. STUDY DESIGN: This is a prospective observational pilot study of 20 third-year medical students. A computerized cognitive function test was administered to students with call every fourth night or a week of 12-hour "night float" shifts. Questionnaires were completed to assess satisfaction on different call schedules. RESULTS: There was no significant difference in cognitive functioning scores for students on either call schedule. Responses on questionnaires indicate that night float allows students to feel more alert for clinical duties (P = .03). CONCLUSION: There is no significant impact of sleep deprivation on cognitive scores; however, night float allows students to feel subjectively more alert for clinical duties.

ABSTRACT

A retrospective cohort study was performed to evaluate IVF clinical pregnancy rates and livebirth rates between patients receiving progesterone supplementation through the first trimester of pregnancy (first trimester protocol) at 12 weeks vs. discontinuation after a positive beta-hCG test 2 weeks after retrieval (luteal protocol) at 4 weeks of pregnancy. A similar rate of clinical pregnancies occurred at 7 weeks (81.8% luteal protocol vs. 85.8% first trimester protocol; P=.49) and for livebirth rates (76.8% luteal protocol vs. 75.0% first trimester protocol; P=.80), but a trend toward a higher rate of pregnancy loss after 7 weeks in the first trimester protocol group occurred (15.5% vs. 4.4%; P=.06), indicating that first trimester progesterone supplementation may support early pregnancy through 7 weeks by delaying miscarriage but does not improve livebirth rates.
