Abstract
PURPOSE Intrauterine insemination (IUI) is a frequently utilized method of assisted reproduction for patients with mild male factor infertility, anovulation, endometriosis, and unexplained infertility. The purpose of this review is to discuss factors that affect IUI outcomes, including infertility diagnosis, semen parameters, and stimulation regimens. METHODS We reviewed the published literature to evaluate how patient and cycle specific factors affect IUI outcomes, specifically clinical pregnancy rate, live birth rate, spontaneous abortion rate and multiple pregnancy rate. RESULTS Most data support IUI for men with a total motile count > 5 million and post-wash sperm count > 1 million. High sperm DNA fragmentation does not consistently affect pregnancy rates in IUI cycles. Advancing maternal and paternal age negatively impact pregnancy rates. Paternal obesity contributes to infertility while elevated maternal BMI increases medication requirements without impacting pregnancy outcomes. For ovulation induction, letrozole and clomiphene citrate result in similar pregnancy outcomes and are recommended over gonadotropins given increased risk for multiple pregnancies with gonadotropins. Letrozole is preferred for obese women with polycystic ovary syndrome. IUI is most effective for women with ovulatory dysfunction and unexplained infertility, and least effective for women with tubal factor and stage III-IV endometriosis. Outcomes are similar when IUI is performed with ovulation trigger or spontaneous ovulatory surge, and ovulation may be monitored by urine or serum. Most pregnancies occur within the first four IUI cycles, after which in vitro fertilization should be considered. CONCLUSIONS Providers recommending IUI for treatment of infertility should take into account all of these factors when evaluating patients and making treatment recommendations.

Low-Dose Urinary Human Chorionic Gonadotropin Is Effective for Oocyte Maturation in In Vitro Fertilization/ Intracytoplasmic Sperm Injection Cycles Independent of Body Mass Index. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2016; 11:7-14. [PMID: 28367299 PMCID: PMC5215713 DOI: 10.22074/ijfs.2016.5145] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/18/2015] [Accepted: 09/04/2016] [Indexed: 01/21/2023]
Abstract
BACKGROUND Currently, there is no agreement on the optimal urinary derived human chorionic gonadotropin (u-hCG) dose requirement for initiating final oocyte maturation prior to oocyte collection in in vitro fertilization (IVF), but doses that range from 2500- 15000 IU have been used. We intended to determine whether low dose u-hCG was effective for oocyte maturation in IVF/intracytoplasmic sperm injection (ICSI) cycles independent of body mass index (BMI). MATERIALS AND METHODS We retrospectively evaluated a cohort of 295 women who underwent their first IVF/ICSI cycles between January 2003 and December 2010 at the Division of Reproductive Endocrinology and Infertility, Wayne State University, Detroit, MI, USA. Treatment cycles were divided into 3 groups based on BMI (kg/ m2): <25 (n=136), 25- <30 (n=84), and ≥30 (n=75) women. Patients received 5000, 10000 or 15000 IU u-hCG for final maturation prior to oocyte collection. The primary outcome was clinical pregnancy rates (CPRs) and secondary outcome was live birth rates (LBRs). RESULTS Only maternal age negatively impacted (P<0.001) CPR [odds ratio (OR=0.85, confidence interval (CI: 0.79-0.91)] and LBR (OR=0.84, CI: 0.78-0.90). CONCLUSION Administration of lower dose u-hCG was effective for oocyte maturation in IVF and did not affect the CPRs and LBRs irrespective of BMI. Women's BMI need not be taken into consideration in choosing the appropriate dose of u-hCG for final oocyte maturation prior to oocyte collection in IVF. Only maternal age at the time of IVF negatively influenced CPRs and LBRs in this study.

Abstract
CONTEXT Obese women have poorer in vitro fertilization outcomes, but underlying mechanisms remain unclear. OBJECTIVE The objectives of the study were to compare the pharmacokinetics of human chorionic gonadotropin (hCG) and ovarian steroid hormone production, after subcutaneous (s.c.) and intramuscular (i.m.) injection of hCG in obese and normal-weight women. DESIGN AND SETTING This was a randomized, experimental study. PATIENTS OR OTHER PARTICIPANTS Twenty-two women aged 18-42 years with body mass index of 18.5-24.9 (normal) or 30-40 kg/m(2) (obese). INTERVENTIONS Participants received im urinary hCG or s.c. recombinant hCG and returned for a second injection type after a 4-week washout. Intramuscular injections were performed under ultrasound guidance. Blood was taken 0, 0.5, 1, 2, 4, 6, 8, 12, 24, and 36 hours after injection. MAIN OUTCOME MEASURES hCG was measured at each time point; estradiol, progesterone, 17-hydroxyprogesterone (17-OHP), testosterone (T), dehydroepiandrosterone, and SHBG were measured at 0 and 36 hours. RESULTS Twenty-two women completed the study. In both normal-weight and obese women, peak serum concentration (Cmax), area under the curve (AUC), and average hCG concentration were higher after i.m. injection as compared with s.c. injection (all P < .003). Obese women had markedly lower Cmax, AUC, and average hCG concentration after s.c. injection as compared with normal-weight women (P = .02, P = .009, and P = .008, respectively). After i.m. injection, Cmax, AUC, and average concentration were similar for normal-weight and obese women (P = .31, P = .25, and P = .18, respectively). Thirty-six percent of obese women had muscular layers beyond the reach of a standard 1.5 inch needle. hCG caused a significant rise in 17-OHP in both obese and normal-weight women and an increase in T in obese but not normal-weight women (all P < .04). CONCLUSIONS Subcutaneous injection yields lower hCG levels in obese women. Standard-length needles are insufficient to administer i.m. injections in many obese women.

Abstract
OBJECTIVE To evaluate the correlation of preretrieval quantitative serum hCG level with oocyte maturity. DESIGN Retrospective cohort study. SETTING Military assisted reproductive technology (ART) program. PATIENT(S) Fresh autologous ART cycles. INTERVENTION(S) Serum hCG level the day before oocyte retrieval. MAIN OUTCOME MEASURE(S) Linear regression was used to correlate serum hCG levels and oocyte maturity rates. Normal oocyte maturity was defined as ≥75% and the Wilcoxon rank sum test was used to compare serum hCG levels in patients with normal and low oocyte maturity. Threshold analysis was performed to determine hCG levels that could predict oocyte maturity. RESULT(S) A total of 468 ART cycles were analyzed. Serum hCG level was not correlated with hCG dose; however, it was negatively correlated with body mass index (BMI). Serum hCG levels did not differ between patients with oocyte maturity of <75% and ≥75%. Serum hCG levels did not correlate with oocyte maturity rates. Receiver operator characteristic and less than efficiency curves failed to demonstrate thresholds at which hCG could predict oocyte maturity. CONCLUSION(S) Serum hCG levels were not correlated with oocyte maturity. Although a positive hCG was reassuring that mature oocytes would be retrieved for most patients, the specific value was not helpful.

Abstract
BACKGROUND To report on relationships among baseline serum anti-Müllerian hormone (AMH) measurements, blastocyst development and other selected embryology parameters observed in non-donor oocyte IVF cycles. METHODS Pre-treatment AMH was measured in patients undergoing IVF (n = 79) and retrospectively correlated to in vitro embryo development noted during culture. RESULTS Mean (+/- SD) age for study patients in this study group was 36.3 ± 4.0 (range = 28-45) yrs, and mean (+/- SD) terminal serum estradiol during IVF was 5929 +/- 4056 pmol/l. A moderate positive correlation (0.49; 95% CI 0.31 to 0.65) was noted between basal serum AMH and number of MII oocytes retrieved. Similarly, a moderate positive correlation (0.44) was observed between serum AMH and number of early cleavage-stage embryos (95% CI 0.24 to 0.61), suggesting a relationship between serum AMH and embryo development in IVF. Of note, serum AMH levels at baseline were significantly different for patients who did and did not undergo blastocyst transfer (15.6 vs. 10.9 pmol/l; p = 0.029). CONCLUSIONS While serum AMH has found increasing application as a predictor of ovarian reserve for patients prior to IVF, its roles to estimate in vitro embryo morphology and potential to advance to blastocyst stage have not been extensively investigated. These data suggest that baseline serum AMH determinations can help forecast blastocyst developmental during IVF. Serum AMH measured before treatment may assist patients, clinicians and embryologists as scheduling of embryo transfer is outlined. Additional studies are needed to confirm these correlations and to better define the role of baseline serum AMH level in the prediction of blastocyst formation.

Abstract
These data suggest that the physiologic stress associated with two consecutive freeze-thaw processes is likely minor. Dual freeze-thaw of embryos does not appear to adversely impact delivery rate in IVF; a livebirth delivery rate of 35.7% per transfer was observed in our population.

Abstract
Background To describe immune and endocrine responses in severe hymenoptera hypersensitivity requiring venom immunotherapy (VIT) during in vitro fertilization (IVF). Case presentation A 39-year old patient was referred for history of multiple miscarriage and a history of insect sting allergy. Four years earlier, she began subcutaneous injection of 100 mcg mixed vespid hymenoptera venom/venom protein every 5–6 weeks. The patient had one livebirth and three first trimester miscarriages. Allergy treatment was maintained for all pregnancies ending in miscarriage, although allergy therapy was discontinued for the pregnancy that resulted in delivery. At our institution ovulation induction incorporated venom immunotherapy (VIT) during IVF, with a reduced VIT dose when pregnancy was first identified. Serum IgE was monitored with estradiol during ovulation induction and early pregnancy. Response to controlled ovarian hyperstimulation was favorable while VIT was continued, with retrieval of 12 oocytes. Serum RAST (yellow jacket) IgE levels fluctuated in a nonlinear fashion (range 36–54%) during gonadotropin therapy and declined after hCG administration. A healthy female infant was delivered at 35 weeks gestation. The patient experienced no untoward effects from any medications during therapy. Conclusion Our case confirms the safety of VIT in pregnancy, and demonstrates RAST IgE can remain <60% during IVF. With proper monitoring, VIT during IVF can be safe and appropriate for selected patients and does not appear to adversely affect blastocyst implantation, early embryo development or perinatal outcome. Further studies will be needed to develop VIT guidelines specifically applicable to IVF.

Abstract
Human chorionic gonadotropin (hCG) preparations have been widely used as a surrogate for the mid-cycle luteinizing hormone (LH) surge for several decades. The urinary source of hCG preparations was favored for many years because of the easy collection of the starting material. However, the final structure of these urinary-derived preparations appears to be quite different from the natural placenta product. Furthermore, many disadvantages of these commercial preparations have been reported, such as local adverse events and immunologic reactions. The recent advent of recombinant DNA technology has now made recombinant hCG (r-hCG) available. This new product ensures high purity and batch-to-batch consistency. The pharmacokinetic and pharmacodynamic profiles of both urinary and recombinant preparations are quite similar. In clinical practice, several trials have been performed to compare both the efficacy and safety of urinary hCG (u-hCG) and r-hCG preparations. Overall, the reported data show that r-hCG preparations are at least as effective as u-hCG products in reproducing the follicular events surrounding the endogenous LH surge. Moreover, the r-hCG products ensure a better hormonal environment during the luteal phase. Finally, the overall tolerability of r-hCG preparations has been shown to be much better than that of u-hCG preparations. As a consequence, the newly available r-hCG preparations offer the first opportunity for clinicians to treat anovulatory women with a full range of recombinant products.

Abstract
OBJECTIVE To report the first conception and delivery following transfer of thawed human blastocysts maintained in extended in vitro culture with cryopreservation at day 6 and 7. DESIGN Case report. SETTING Major urban infertility referral center. PATIENT(S) A 26-year-old woman with pelvic endometriosis and two prior unsuccessful in vitro fertilization/embryo transfer (IVF-ET) attempts. INTERVENTION(S) The patient underwent controlled ovarian hyperstimulation using a combined FSH + hMG protocol, and 24 oocytes were retrieved. MAIN OUTCOME MEASURE(S) Dizygotic twin delivery after IVF and intracytoplasmic sperm injection (ICSI), assisted embryo hatching, and ultrasound-guided transfer of cryopreserved blastocysts. RESULT(S) After three embryos were subjected to assisted hatching, they were transferred fresh on day 3, but no implantation occurred. All nontransferred embryos (n = 11) were observed during extended in vitro culture and three blastocysts were selected for cryopreservation on day 6 and 7; thaw and transfer occurred the following month and a pregnancy was achieved. Dizygotic twins (female/female) were delivered by cesarean in the early third trimester. CONCLUSION(S) Substantial advancements have been made in the field of embryo cryogenics and in vitro fertilization, but controversy remains regarding the value of freezing late-developing human blastocysts. Here we describe the first reported live births with IVF after extended in vitro culture and cryopreservation at day 6 and 7 after fertilization.

Abstract
BACKGROUND: We present a case of primary infertility related to extreme cervical stenosis, a subset of cervical factor infertility which accounts for approximately 5% of all clinical infertility referrals. CASE PRESENTATION: A 37 year-old nulligravida was successfully treated with ovulation induction via recombinant follicle stimulating hormone (FSH) and direct intraperitoneal insemination (IPI). Anticipating controlled ovarian hyperstimulation with in vitro fertilization/embryo transfer (IVF), the patient underwent hysteroscopy and cervical recanalization, but safe intrauterine access was not possible due to severe proximal cervical stricture. Hysterosalpingogram established bilateral tubal patency and confirmed an irregular cervical contour. Since the cervical canal could not be traversed, neither standard intrauterine insemination nor transcervical embryo transfer could be offered. Prepared spermatozoa were therefore placed intraperitoneally at both tubal fimbria under real-time transvaginal sonographic guidance using a 17 gage single-lumen IVF needle. Supplementary progesterone was administered as 200 mg/d lozenge (troche) plus 200 mg/d rectal suppository, maintained from the day following IPI to the 8th gestational week. A singleton intrauterine pregnancy was achieved after the second ovulation induction attempt. CONCLUSIONS: In this report, we outline the relevance of cervical factor infertility to reproductive medicine practice. Additionally, our andrology evaluation, ovulation induction approach, spermatozoa preparation, and insemination technique in such cases are described.
