Gonadotropin-releasing hormone agonist trigger increases the number of oocytes and embryos available for cryopreservation in cancer patients undergoing ovarian stimulation for fertility preservation.

OBJECTIVE: To compare the oocyte and embryo yield associated with GnRH-agonist triggers vs. hCG triggers in cancer patients undergoing controlled ovarian stimulation (COS) for fertilization preservation. DESIGN: Retrospective cohort study. SETTING: Academic center. PATIENT(S): Cancer patients undergoing COS with letrozole and gonadotropins or gonadotropin-only protocols for oocyte or embryo cryopreservation. INTERVENTION(S): Gonadotropin-releasing hormone agonist or hCG trigger. MAIN OUTCOME MEASURE(S): Number of metaphase II (MII) oocytes or two-pronuclei (2PN) embryos available for cryopreservation were primary outcomes. Separate multivariate linear regression models were used to assess the effect of trigger type on the primary outcomes, after controlling for confounders of interest. RESULT(S): A total of 341 patients were included, 99 (29.0%) in the GnRH-agonist group and 242 (71%) in the hCG group. There was no difference in the baseline demographics of patients receiving GnRH-agonist or hCG triggers. Within the letrozole and gonadotropins group (n = 269), the number (mean ± SD, 11.8 ± 5.8 vs. 9.9 ± 6.0) and percentage of MII oocytes (89.6% vs. 73.0%) available for cryopreservation was higher with GnRH-agonist triggers compared with hCG triggers. Similar results were noted with GnRH-agonist triggers in the gonadotropin-only group (n = 72) (i.e., a higher number [13.3 ± 7.9 vs. 9.3 ± 6.0] and percentage of MII oocytes [85.7% vs. 72.8%] available for cryopreservation). Multivariate linear regression demonstrated approximately three more MII oocytes and 2PN embryos available for cryopreservation in the GnRH-agonist trigger group, irrespective of cancer and COS protocol type. CONCLUSION(S): Utilization of a GnRH-agonist trigger increases the number of MII oocytes and 2PN embryos available for cryopreservation in cancer patients undergoing COS for fertility preservation.

Random Start Ovarian Stimulation for Oocyte or Embryo Cryopreservation in Women Desiring Fertility Preservation Prior to Gonadotoxic Cancer Therapy.

BACKGROUND: Women of reproductive age diagnosed with cancer are often interested in preserving gametes or reproductive tissue that would allow for future genetic parenthood. Preservation of fertility is often accomplished in young cancer patients via ovarian stimulation followed by oocyte or embryo cryopreservation. Conventional stimulation protocols, however, require 2-4 weeks to complete ovarian stimulation, oocyte retrieval and possible fertilization. Such a strategy may not be feasible in patients requiring urgent cancer treatment. Recent studies have highlighted that random start ovarian stimulation can be initiated irrespective of the phase of the menstrual cycle and is an attractive alternative to conventional ovarian stimulation. The primary aim of the current review is to discuss the feasibility and success of random start ovarian stimulation for oocyte or embryo cryopreservation in women desiring fertility preservation prior to gonadotoxic cancer therapy. METHOD: We performed a systematic review of medical literature published between January 2000 to June 2017 reporting the utility of random start ovarian stimulation for fertility preservation. Search terms included "fertility preservation," "cancer," "ovarian stimulation," "random-start ovarian stimulation," "embryo cryopreservation, and" "oocyte cryopreservation." Publications were included in this review only if patients underwent random start ovarian stimulation prior to cancer therapy. RESULTS: Nineteen publications were identified and perused by the authors. Most publications described the utility of random start ovarian stimulation in the setting of breast cancer. Radom-start stimulation was associated with a reduced time interval between ovarian stimulation initiation and oocyte or embryo cryopreservation. The yield of mature oocytes and their developmental potential into embryos was comparable between conventional and random-start protocols, albeit with higher gonadotropin doses in the latter. CONCLUSION: The current review suggests that random start ovarian stimulation can shorten the interval between ovarian stimulation and oocyte retrieval, with the yield of oocytes and embryos being comparable to conventional stimulation protocols. Thus, random start ovarian stimulation may serve as a better option for fertility preservation in patients requiring urgent cancer treatment.

Combined GnRH-agonist and human chorionic gonadotropin trigger improves ICSI cycle outcomes in patients with history of poor fertilization.

PURPOSE: The purpose of this study was to investigate the utility of a combined GnRH-agonist (GnRH-a) and human chorionic gonadotropin (hCG) trigger in improving ICSI cycle outcomes in patients with poor fertilization history after standard hCG trigger in prior ICSI cycles. METHODS: Retrospective cohort study. Patients with a fertilization rate of <20% in at least two prior ICSI cycles who subsequently underwent another ICSI cycle with hCG trigger were compared to those who underwent another ICSI cycle with a combined GnRH-a and hCG trigger. Oocyte maturity, fertilization, clinical pregnancy, and live birth rates were compared. A multiple linear regression model was used to explore the association between combined GnRH-a and hCG trigger (vs hCG trigger alone) and fertilization rate. RESULTS: A total of 427 patients with mean age of 37.3 ± 1.94 years and mean baseline fertilization rate of 17.9 ± 2.03% were included, of which 318 (74.5%) and 109 (25.5%) patients underwent a subsequent ICSI cycle with hCG and combined GnRH-a and hCG trigger, respectively. The baseline parameters of the male and female partner were similar. The mean fertilization rate in the combined trigger group was 16.4% (95% CI: 7.58-25.2%) higher than the hCG trigger group, even after adjustment for confounders. Patients in the combined trigger group had higher oocyte maturity (82.1 vs 69.8%), higher clinical pregnancy (27.5 vs 5.67%), and higher live birth rates (20.2 vs 3.46%) compared to the hCG trigger group. CONCLUSIONS: Combined GnRH-a and hCG trigger in ICSI cycles increase oocyte maturity, fertilization, clinical pregnancy, and live birth rates in patients with a history of poor fertilization after standard hCG trigger alone.

Temporal trends in minimally invasive myomectomy before and after the US Food and Drug Administration recommendation against electric morcellation.

OBJECTIVE: To investigate the temporal trends in minimally invasive myomectomy at one reproductive medicine center before and after the US Food and Drug Administration (FDA) recommendation against electric morcellation. METHODS: A retrospective chart review was undertaken of patients undergoing minimally invasive myomectomy between April 1, 2012, and April 30, 2016, at a center in New York. Temporal trends in laparoscopic myomectomy (LM), robot-assisted laparoscopic myomectomy (RAM), and laparoscopically assisted myomectomy (LAM), and intraoperative and postoperative outcomes before and after the April 2014 recommendation were compared. RESULTS: Minimally invasive myomectomy was performed in 73 patients. No difference was noted in the rates of minimally invasive myomectomy 2 years before (35/74 [47.3%]) and after (38/79 [48.1%]) the FDA's recommendation. The ratio of abdominal to minimally invasive myomectomy remained relatively constant before (68/59=1.15) and during the study period (80/73=1.10). There was a significant decrease in LM and RAM and a corresponding rise in LAM immediately after the recommendation (P<0.001). CONCLUSION: The rates of minimally invasive myomectomy before and after the FDA's recommendation did not differ, indicating that technical modifications to laparoscopic technique can allow surgeons to offer minimally invasive myomectomy to patients with symptomatic leiomyomas.

Ovarian Response and in Vitro Fertilization Outcomes After Salpingectomy: Does Salpingectomy Indication Matter?

STUDY OBJECTIVE: To investigate whether the ovarian response and pregnancy outcomes of patients undergoing in vitro fertilization (IVF) after salpingectomy are affected by the underlying indication for salpingectomy. DESIGN: Retrospective cohort study (Canadian Task Force classification II-3). SETTING: University-affiliated fertility center. PATIENTS: All patients age <37 years undergoing IVF within 12 months of laparoscopic salpingectomy. The underlying indication for laparoscopic salpingectomy in the study cohort was tubal ectopic pregnancy, unilateral or bilateral hydrosalpinx, or other reason (hematosalpinx or pyosalpinx), as confirmed by histopathology. INTERVENTIONS: IVF and embryo transfer (ET). MEASUREMENTS AND MAIN RESULTS: Surgical characteristics, demographics, ovarian stimulation parameters, total oocytes retrieved, fertilization rates, implantation rates, and clinical pregnancy rates were compared among the salpingectomy groups. Age- and time-matched patients undergoing their first IVF-ET cycle for male factor infertility, with no previous history of laparoscopy, served as controls. RESULTS: Of the 996 patients who underwent a laparoscopic procedure during the study period, 136 patients underwent unilateral salpingectomy for the following indications: 39 for ectopic pregnancy, 81 for unilateral hydrosalpinx, and 16 for other indications. Among these 136 patients, 29 in the ectopic pregnancy group, 75 in the unilateral hydrosalpinx group, and 10 in the "other" group underwent subsequent IVF-ET. Thirty-one patients underwent both bilateral salpingectomy and subsequent IVF-ET. There was no difference in the antral follicle counts before and after salpingectomy in all groups. There was a statistically significant difference in the mean duration of ovarian stimulation in the salpingectomy groups: ectopic pregnancy, 10.9 ± 2.15 days; unilateral hydrosalpinx, 9.56 ± 1.95 days; bilateral hydrosalpinx, 9.51 ± 2.01 days; "other", 9.89 ± 2.20 days; control, 9.76 ± 1.99 days. Similar trends were noted for total gonadotropins administered when comparing the ectopic pregnancy group (3375.9 ± 931.0 IU) with the remaining groups (unilateral hydrosalpinx, 2841.3 ± 1160.9 IU; bilateral hydrosalpinx, 2519.3 ± 1004.7 IU; "other", 2808.6 ± 990.1 IU; control, 2726.1 ± 1129.8 IU). There were no significant differences in the total number of oocytes retrieved, fertilization rate, implantation rate, or clinical pregnancy rate in the salpingectomy groups compared with controls. CONCLUSION: Although our findings indicate that patients undergoing IVF after salpingectomy for an ectopic pregnancy have a statistically significantly longer duration of stimulation and require higher gonadotropin doses compared with patients undergoing IVF after salpingectomy for other indications, these differences are of limited clinical significance, given that the total number of oocytes retrieved, implantation rate, and clinical pregnancy rate among the different salpingectomy groups are comparable to those in controls.

Abdominal ectopic pregnancy with undetectable serum ß-human chorionic gonadotropin 9 days following blastocyst transfer.

With the availability of the highly sensitive ß-human chorionic gonadotropin (ß-hCG) assays, all pregnancies, including ectopic pregnancies (EP), are expected to have detectable serum ß-hCG at 4 weeks' gestation or 9 days following blastocyst transfer. To our knowledge, this is the first report of a woman who underwent in vitro fertilization, had undetectable serum ß-hCG 9 days after blastocyst transfer, and was then diagnosed with a ruptured abdominal EP and intra-abdominal bleeding 19 days later. This case highlights that the rise in serum ß-hCG might be delayed in abdominal EP compared to intrauterine pregnancy. This delay should raise the suspicion for EP, thus meriting close monitoring. Moreover, in the absence of menstruation, an undetectable serum ß-hCG 9 days post-blastocyst transfer should prompt ß-hCG measurement in 2-3 days to avoid the misdiagnosis of an EP.

Adjuvant gonadotrophin-releasing hormone agonist trigger with human chorionic gonadotrophin to enhance ooplasmic maturity.

This study investigates whether an adjuvant gonadotrophin-releasing hormone agonist (GnRHa) trigger with human chorionic gonadotrophin (HCG) improves fresh intracytoplasmic sperm injection (ICSI) cycle outcomes in patients with poor fertilization history after standard HCG trigger alone. This study compared 156 patients with <40% fertilization rate in a prior ICSI cycle with standard HCG trigger who underwent another ICSI cycle with a combined 2 mg GnRHa and 1500 IU HCG ovulatory trigger. There was no difference in the baseline demographics, ovarian stimulation outcomes or sperm parameters of the groups. More mature oocytes were retrieved in the combined trigger group compared with the HCG trigger group: 12 (9-14) versus 10 (7-12); P = 0.01. The fertilization rate in the combined trigger group (59.2%) was higher than the HCG group (35.3%); P = 0.01. The odds of clinical pregnancy and live birth were 1.8 and 1.7 times higher, respectively, when comparing the former group to the latter; P = 0.03. The results suggest that combined GnRHa and HCG trigger in ICSI cycles is a reasonable approach to increase oocyte maturity, specifically ooplasmic maturity, thereby increasing fertilization and improving ICSI cycle outcomes in patients with a history of poor fertilization after standard HCG trigger alone.

Does the time interval between hysteroscopic polypectomy and start of in vitro fertilization affect outcomes?

OBJECTIVE: To investigate whether the time interval between hysteroscopic polypectomy and the start of IVF-ET cycles affect IVF cycle outcomes. DESIGN: Retrospective cohort. SETTING: Academic center. PATIENT(S): All patients diagnosed with endometrial polyps undergoing hysteroscopic polypectomy before fresh IVF-ET. INTERVENTION(S): Hysteroscopic polypectomy. MAIN OUTCOME MEASURE(S): Patients were divided into three groups based on the time interval between hysteroscopic polypectomy and the start of a fresh IVF-ET cycle. Group 1 consisted of patients who underwent IVF-ET after their next menses, group 2 after two or three menstrual cycles, and group 3 after more than three menstrual cycles. Demographics, baseline IVF characteristics, controlled ovarian stimulation response, and pregnancy outcomes after ET were compared among the groups. RESULT(S): A total of 487 patients met inclusion criteria: 241 in group 1 (49.5%), 172 in group 2 (35.3%), and 74 in group 3 (15.2%). There were no differences in the baseline characteristics of the three groups. Ovarian stimulation outcomes, specifically total stimulation days, total gonadotropins administered, and number of oocytes retrieved, were similar between groups. There were no differences in the mean number of embryos transferred. The overall pregnancy outcomes were similar for groups 1, 2, and 3: implantation rate (42.4%, 41.2%, and 42.1%, respectively), clinical pregnancy rate (48.5%, 48.3%, and 48.6%), spontaneous miscarriage rate (4.56%, 4.65%, and 4.05%), and live birth rate (44.0, 43.6%, and 44.6%). CONCLUSION(S): Because waiting for two or more menstrual cycles after hysteroscopic polypectomy does not necessarily yield superior outcomes, patients can undergo ovarian stimulation after their next menses without affecting IVF-ET outcomes.

Human Papillomavirus Infection, Infertility, and Assisted Reproductive Outcomes.

The human papillomavirus (HPV) is a sexually transmitted infection common among men and women across all geographic and socioeconomic subgroups worldwide. Recent evidence suggests that HPV infection may affect fertility and alter the efficacy of assisted reproductive technologies. In men, HPV infection can affect sperm parameters, specifically motility. HPV-infected sperm can transmit viral DNA to oocytes, which may be expressed in the developing blastocyst. HPV can increase trophoblastic apoptosis and reduce the endometrial implantation of trophoblastic cells, thus increasing the theoretical risk of miscarriage. Vertical transmission of HPV during pregnancy may be involved in the pathophysiology of preterm rupture of membranes and spontaneous preterm birth. In patients undergoing intrauterine insemination for idiopathic infertility, HPV infection confers a lower pregnancy rate. In contrast, the evidence regarding any detrimental impact of HPV infection on IVF outcomes is inconclusive. It has been suggested that vaccination could potentially counter HPV-related sperm impairment, trophoblastic apoptosis, and spontaneous miscarriages; however, these conclusions are based on in vitro studies rather than large-scale epidemiological studies. Improvement in the understanding of HPV sperm infection mechanisms and HPV transmission into the oocyte and developing blastocyst may help explain idiopathic causes of infertility and miscarriage.

Surgical Management of Endometrial Polyps in Infertile Women: A Comprehensive Review.

Endometrial polyps are benign localized lesions of the endometrium, which are commonly seen in women of reproductive age. Observational studies have suggested a detrimental effect of endometrial polyps on fertility. The natural course of endometrial polyps remains unclear. Expectant management of small and asymptomatic polyps is reasonable in many cases. However, surgical resection of endometrial polyps is recommended in infertile patients prior to treatment in order to increase natural conception or assisted reproductive pregnancy rates. There is mixed evidence regarding the resection of newly diagnosed endometrial polyps during ovarian stimulation to improve the outcomes of fresh in vitro fertilization cycles. Hysteroscopy polypectomy remains the gold standard for surgical treatment. Evidence regarding the cost and efficacy of different methods for hysteroscopic resection of endometrial polyps in the office and outpatient surgical settings has begun to emerge.

Impact of newly diagnosed endometrial polyps during controlled ovarian hyperstimulation on in vitro fertilization outcomes.

STUDY OBJECTIVE: To investigate the impact of newly diagnosed endometrial polyps during controlled ovarian hyperstimulation (COH) on the outcomes of fresh in vitro fertilization (IVF)-embryo transfer (ET) cycles. DESIGN: A retrospective cohort study (Canadian Task Force classification II-3). SETTING: An academic center. PATIENTS: All patients initiating IVF cycles at the Ronald O. Perelman and Claudia Cohen Center for Reproductive Medicine during a 1-year period. Patients were stratified into 2 groups based on the presence or absence of newly diagnosed endometrial polyps during COH. INTERVENTIONS: IVF with fresh ET. MEASUREMENTS AND MAIN RESULTS: Two thousand nine hundred ninety-three patients were identified: 60 in the polyp group and 2933 in the nonpolyp group. The overall positive pregnancy, clinical pregnancy, spontaneous miscarriage, and live birth rates were similar between the groups. The biochemical pregnancy rate was 18.3% in the polyp group compared with 9.6% in the nonpolyp group (p = .01). This represented a 2-fold increased odds of biochemical pregnancy in the polyp group (odds ratio = 2.12; 95% confidence interval, 1.09-4.12) compared with the nonpolyp group. CONCLUSION: Newly diagnosed endometrial polyps during COH is associated with an increased biochemical pregnancy rate but ultimately does not adversely impact clinical pregnancy or live birth rates after fresh IVF-ET.

The role of laparoscopy in the treatment of early ovarian carcinoma.

Laparoscopic management of early ovarian cancer (EOC) has constituted a controversial issue since it was first described. Recent data reinforced the arguments supporting the use of laparoscopy in the management of EOC. Advances in laparoscopy have enabled surgeons to meet the International Federation of Gynecology and Obstetrics' criteria for staging of EOC. Although most study results are encouraging, the sample size is still too small to be able to draw definite conclusions. Frequently cited concerns such as accuracy of staging, intraabdominal tumor rupture and port site metastasis should not be used as arguments against laparoscopic management of EOC. Clinical evidence is clearly in favor of a larger role for laparoscopy in the management of EOC. This should encourage studies with larger sample sizes to confirm the validity of laparoscopic management of EOC.
