Euploidy rates of embryos in young patients with good and low prognosis according to the POSEIDON criteria.

RESEARCH QUESTION: Does an association exist between ovarian reserve, ovarian response and embryonic euploidy in female patients under age 35 years? DESIGN: This was a retrospective analysis of intracytoplasmic sperm injection and preimplantation genetic testing for aneuploidies cycles among patients enrolled at Bahceci Fulya IVF Center between January 2016 and August 2019. A total of 133 patients in POSEIDON group 1 (suboptimal responder; female age <35 years, antral follicle count [AFC] ≥5, number of oocytes retrieved <10) (group A), 133 patients in POSEIDON group 3 (expected low responder; female age <35 years, AFC <5) (group B) and 323 in the non-low-prognosis group (female age <35 years, AFC ≥5 and number of oocytes retrieved >9) (group C) were included. RESULTS: There was no significant difference in euploidy rate per embryo among the three groups (61.7% [145/235] for group A versus 53.5% [68/127] for group B versus 62% [625/1008] for group C; P = 0.13). The cancellation rate in cycles without a euploid blastocyst was significantly lower in group C than groups A and B (8.4% versus 12.8% and 16.5%; P = 0.034). Multivariate regression analysis indicated that the ovarian response group did not significantly affect the probability of obtaining a euploid embryo. Trophectoderm score 'C' (odds ratio 0.520, P = 0.007) and inner cell mass score 'C' (odds ratio 0.480, P < 0.001) were associated with a decreased probability of obtaining a euploid embryo. CONCLUSIONS: These results confirm that POSEIDON group 1 and group 3 and non-low-prognosis patients have different probabilities of euploid embryos being obtained per cycle. However, euploidy rates per embryo are not affected by the patient's ovarian reserve and response.

The impact of patient, embryo, and translocation characteristics on the ploidy status of young couples undergoing preimplantation genetic testing for structural rearrangements (PGT-SR) by next generation sequencing (NGS).

PURPOSE: To evaluate the factors that affect the incidence of euploid balanced embryos and interchromosomal effect (ICE) in carriers of different structural rearrangements. METHODS: This retrospective study includes 95 couples with reciprocal translocations (RecT) and 36 couples with Robertsonian translocations (RobT) undergoing Preimplantation Genetic Testing for Structural Rearrangements (PGT-SR) between March 2016 and July 2019. Next-generation sequencing (NGS) was the technique used coupled with trophectoderm (TE) biopsy. Only cases with females under 38 years were included. A total of 532 blastocysts were evaluated. RESULTS: The euploidy rate was similar in RobT when compared with RecT carriers [57/156 (36.5%) vs. 112/376 (29.8%), p = 0.127]. The pure ICE rate was significantly higher in RobT carriers [48/156 (30.8%) vs. 53/376 (14.1%), p < 0.001] than it was in RecT carriers. Female age was the independent factor for the probability of obtaining a euploid embryo in RecT and RobT carriers, and increasing female age decreases the probability of obtaining a euploid embryo. In RecT carriers, no significant differences were observed in euploidy rates, pure ICE, or combined ICE according to the length of the translocated fragment and the chromosome group. However, total ICE was significantly lower when there was a breakpoint in the short chromosome arm together with a breakpoint in the long arm [(44/158 (27.8%) for pq or qp, 51/155 (32.9%) for pp and 30/63 (47.6%) for qq; p = 0.02]. CONCLUSION: The incidence of euploid/balanced blastocysts was similar in both types of translocations. However, there was a significant increase in pure ICE in RobT compared to RecT carriers. In RecT carriers, the presence of the breakpoints in the long arm of the chromosomes involved in the rearrangement resulted in a higher total ICE.

Subcutaneous progesterone administration provides a similar ongoing pregnancy rate compared with intramuscular progesterone administration in hormone replacement therapy frozen embryo transfer cycles.

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.

Ovarian stimulation in women with high and low body mass index: GnRH agonist versus GnRH antagonist.

This study evaluated women with a high body mass index (BMI) (>40 kg/m(2)) and low BMI (<18 kg/m(2)) undergoing assisted reproduction treatment and determined whether the type of gonadotrophin-releasing hormone (GnRH) analogue used has an impact on cycle parameters and outcome. The study analysed 65 women with high BMI and 118 with low BMI. In the former group, polycystic ovarian syndrome was significantly more prevalent in the agonist long protocol (ALP) group (P=0.01) and gonadotrophin consumption was lower, peak oestradiol concentrations and total number of oocytes retrieved were higher in the ALP group compared with the antagonist (ANT) group. Implantation rate (IR), pregnancy rate (PR) per embryo transfer and early pregnancy loss rate (EPLR) were similar in both stimulation groups, with overall rates of 21.6%, 55.4% and 44.4%, respectively. In women with low BMI, peak oestradiol concentrations, total oocytes retrieved, mature oocytes and transferred embryos were higher in the ALP group compared with ANT group. IR, PR/embryo transfer and EPLR were similar in both groups, with overall rates of 24.3%, 52.5% and 16.1%, respectively. In all patients, no difference was found between ALP and ANT protocols concerning treatment outcome. Contrary to the reasonable EPLR observed in women with low BMI, the high rate found in women with high BMI is remarkable.

A genetic survey of 1935 Turkish men with severe male factor infertility.

Male factor infertility is the sole reason in approximately 25% of couples who suffer from infertility. Genetic factors such as numerical and structural chromosomal abnormalities and microdeletions of the Y chromosome might be the cause of poor semen parameters. The results of karyotype analyses and Y-chromosome microdeletions of 1935 patients with severe male factor infertility, which is the largest series from Turkey, were assessed retrospectively. The frequency of cytogenetic abnormalities among 1214 patients with non-obstructive azoospermia (NOA) and 721 patients with severe oligoasthenoteratozoospermia (OAT) were 16.40 and 5.83% respectively. The overall incidence of Y-chromosome microdeletion was 7.70%. The incidence of Y chromosome microdeletion in patients with NOA and OAT was 9.51 and 1.86% respectively. The abnormality rate increased with the severity of infertility. Some patients (n = 22) were carriers of both chromosomal abnormalities and Y-chromosome microdeletions. Results suggest the need for genetic screening and proper genetic counselling before initiation of assisted reproduction treatment.

Assisted reproductive technique outcome in testicular sperm extraction-intracytoplasmic sperm injection cycles with poor female response: a report on 8 years' experience.

OBJECTIVE: To evaluate the outcome in couples composed of azoospermia and a poor responder female undergoing assisted reproductive techniques (ARTs). STUDY DESIGN: A retrospective study was performed involving 97 men suffering from nonobstructive azoospermia (NOA) whose partners had a poor response to ovarian stimulation. Poor response was defined as retrieval of fewer than 5 oocytes. Main outcome measures were implantation rate (IR), clinical pregnancy rate per embryo transfer (CPR/ET) and early pregnancy loss rate (EPLR). RESULTS: Overall IR, CPR/ET and EPLR were found to be 16%, 23% and 15%, respectively, which were significantly lower than those in NOA men with normoresponder partners except EPLR (25%, 52% and 24%, respectively). When the results were further stratified according to number of oocytes retrieved and body mass index, no significant difference was observed between the groups. However, when the results were analyzed according to the woman's age, a significantly lower CPR/ ET was found in poor responder women aged > or = 38 years (11% vs. 33%; p = 0.03). CONCLUSION: Although success of ART is suggested to be high once motil spermatozoa are found in testicular sperm extraction in NOA cases, poor response to ovarian stimulation might be considered as one of the strongest determinants of the outcome.

In vitro fertilization in normoresponder patients with endometriomas: comparison with basal simple ovarian cysts.

OBJECTIVE: To investigate whether the space-occupying effect of an endometrioma, rather than endometriosis itself, affects results in in vitro fertilization (IVF) using women with simple ovarian cysts as the control group. METHODS: 85 normoresponder patients with endometriomas of 10-50 mm who underwent IVF treatment directly without initial removal were compared with 83 normoresponder patients with simple ovarian cysts of 10-35 mm detected at the beginning of stimulation and initiated treatment without aspiration. RESULTS: Gonadotropin consumption was higher in the endometrioma group (3,013 vs. 2,451 IU; p = 0.001), although significantly fewer numbers of oocytes were retrieved (13.9 vs. 16.4; p = 0.03). However, oocyte maturation rates were similar. The transferred grade I embryos ratio was evaluated and found to be better in the cyst group (79.7 vs. 70.7%; p = 0.03). Consequently, the implantation rate was found to be significantly higher in the cyst group (28 vs. 19%; p = 0.02), although pregnancy and ongoing pregnancy rates were similar. CONCLUSION: The presence of an endometriotic cyst during the IVF cycle was demonstrated to be associated with a lower embryo quality and implantation rate, although pregnancy success was unaffected. This adverse effect is suggested to be the result of the disease itself, not the presence of a cystic mass.

Short tandem repeats haplotyping of the HLA region in preimplantation HLA matching.

Recently, preimplantation genetic diagnosis (PGD) has been considered for several indications beyond its original purpose, not only to test embryos for genetic disease but also to select embryos for a nondisease trait, such as specific human leukocyte antigen (HLA) genotypes, related to immune compatibility with an existing affected child in need of a haematopoetic stem cell (HSC) transplant. We have optimized an indirect single-cell HLA typing protocol based on a multiplex fluorescent polymerase chain reaction (PCR) of short tandem repeat (STR) markers scattered throughout the HLA complex. The assay was clinically applied in 60 cycles from 45 couples. A conclusive HLA-matching diagnosis was achieved in 483/530 (91.1%) of the embryos tested. In total, 74 (15.3%) embryos revealed an HLA match with the affected siblings, 55 (11.4%) of which resulted unaffected and 46 (9.5%) have been transferred to the patients. Nine pregnancies were achieved, five healthy HLA-matched children have already been delivered and cord blood HSCs, were transplanted to three affected siblings, resulting in a successful haematopoietic reconstruction.

The efficiency of progesterone vaginal gel versus intramuscular progesterone for luteal phase supplementation in gonadotropin-releasing hormone antagonist cycles: a prospective clinical trial.

We compared the efficiency of progesterone vaginal gel (PVG) with intramuscular progesterone (IMP) supplementation for luteal phase support after in vitro fertilization and embryo transfer in gonadotropin-releasing hormone (GnRH) antagonist cycles. The treatment outcomes were similar for PVG and IMP for luteal support in GnRH-antagonist protocols. With its ease of use, high tolerability by patients, and fewer side effects, PVG can be a successful alternative to IMP.

A prospective, randomized, controlled study to compare two doses of recombinant human chorionic gonadotropin in serum and follicular fluid in woman with high body mass index.

This prospective, randomized, controlled study compares the efficiency of 250 microg or 500 microg of recombinant hCG in serum and follicular fluid (FF) levels and pregnancy rates (PR) in women with high body mass index (BMI) (>or=26 kg/m(2)) undergoing assisted reproduction treatment (ART). Treatment outcomes are similar between the two groups.

Serum oestradiol and beta-HCG measurements after day 3 or 5 embryo transfers in interpreting pregnancy outcome.

The aim of this study was to assess the clinical value of serum oestradiol concentration 8 days after embryo transfer (D8E2) and beta-human chorionic gonadotrophin (HCG-beta) concentration 12 days after embryo transfer (D12HCG-beta) in the prediction of pregnancy and the outcome of pregnancy following assisted reproduction, taking into account the day of transfer, which was either day 3 (D3) or day 5 (D5). The objective was to improve patient counselling by giving quantitative and reliable predictive information instead of non-specific uncertainties. A total of 2035 embryo transfer cycles performed between January 2003 and June 2005 were analysed retrospectively. Biochemical pregnancy, ectopic pregnancy and first-trimester abortions were classified as non-viable pregnancies; pregnancies beyond 12 weeks gestation were classified as ongoing pregnancies (OP). Significantly higher D8E2 and D12HCG-beta were obtained in D5 transfers compared with D3 transfers with regard to pregnancy and OP (P

Young patients with diminished ovarian reserve undergoing assisted reproductive treatments: a preliminary report.

Young assisted-reproduction patients with diminished ovarian reserve (DOR) are one of the most challenging issues for IVF specialists. A retrospective study of 70 assisted reproduction patients younger than 35 years with DOR determined based on antral follicle count was conducted, investigating: (i) correlation of day 3 FSH measurement with antral follicle count; and (ii) cycle outcome of young DOR patients compared with 53 young assisted reproduction patients with normal ovarian reserve (NR). DOR was considered as antral follicle count of <6 per ovary. Day 3 FSH in the DOR group was significantly higher than in the NR group (8.3 and 6.6 mIU/ml respectively; P < 0.05). Implantation rates between the groups were similar (15% in DOR and 18% in NR). Pregnancy rate was 35.8% in the DOR group, significantly lower than that of the NR group, which was 54.7% (P = 0.028). Although the pregnancy rate was significantly lower in the DOR group compared with the NR group, the statistically insignificant difference in implantation rates demonstrated that the problem in young DOR patients was mainly the number of retrieved oocytes. Therefore, such couples should be informed that lower oocyte numbers will result in statistically lower, but still encouraging, pregnancy rates. Basal FSH should also be measured during evaluation as an adjunct to antral follicle count.
