RESUMEN

Data collection regarding the effects of COVID-19 on reproduction is ongoing. This study examined the effect of COVID-19 on IVF cycle parameters and early pregnancy outcomes. It included two arms: the first compared non-exposed cycles to post-SARS-CoV-2 IVF cycles. Sperm parameters were also compared. The second, prospective arm compared pregnancy outcomes among IVF patients who contracted COVID-19 during early pregnancy to those who did not. None of the patients were vaccinated against SARS-CoV-2. The first arm included 60 treatment cycles of women with confirmed COVID-19, compared to 60 non-exposed cycles (either the same patient before exposure or matched non-exposed patients). The outcomes of the treatment cycles did not differ significantly between exposed and non-exposed groups, including number of oocytes, endometrial thickness, fertilization rate and number of top-quality embryos. In 11 cycles, the male partner had also recently recovered: sperm concentration was lower post-exposure: 6.27 million/mL vs. 16.5 pre-exposure (p = 0.008). In 189 patients with IVF-achieved pregnancies, pregnancy loss and hospital admissions did not differ between exposed and non-exposed groups. IVF treatment outcomes and the rate of early pregnancy loss appears to be unaffected by SARS-CoV-2 disease, despite a minor decline in sperm concentration among recent recoverees.

RESUMEN

BACKGROUND: Given the complexity of infertility diagnoses and treatments and the convenience of the internet for finding health-related information, people undergoing infertility treatments often use Web-based resources to obtain infertility information and support. However, little is known about the types of information and support resources infertility patients search for on the internet and whether these resources meet their needs. OBJECTIVE: The aims of this study were to (1) examine what individual factors, namely, demographic characteristics and distress, are associated with searching the internet for different types of infertility-related information and support resources and (2) determine whether Web-based resources meet the needs of patients. METHODS: Men and women seeking infertility care responded to a survey assessing use of Web-based resources for accessing infertility-related information and support. The survey further assessed satisfaction with Web-based resources as well as perceived stress and depressive symptomatology. RESULTS: A total of 567 participants, including 254 men and 313 women, completed the survey. Most participants (490/558, 87.8%) had searched the internet for infertility information and support. Searchers were more likely to be women (P<.001), highly educated (P=.04), long-term patients (P=.03), and more distressed (P=.04). Causes of infertility, treatment options, and scientific literature about infertility were the three most frequently searched topics, whereas ways to discuss treatment with family and friends as well as surrogacy and ways to find peer support were the three least searched topics. Of those who searched the internet, 70.9% (346/488) indicated that their needs were met by Web-based information, whereas 29.1% (142/488) said that their needs were not met. Having unmet needs was related to greater levels of perceived stress (P=.005) and depressive symptomatology (P=.03). CONCLUSIONS: This study provides evidence for the important role of the internet in accessing infertility information and support and for the ability of Web-based resources to meet patients' needs. However, although distressed patients reported particularly high rates of searching, their needs were not always met, suggesting that they may benefit from alternative sources of information and support or guidance from health care providers when searching the internet.

RESUMEN

Prenatal genetic testing is not generally applicable to the very early stages of pregnancy (prior to week 8 gestation), a time period that is crucial to pregnant couples with high risk for transmission of genetic disease to their fetus. Therefore, we developed a new ultra-sensitive targeted next generation sequencing method for noninvasive haplotype-based paternal allele exclusion testing of the cystic fibrosis-associated gene, CFTR. This new method was compared to a conventional library prep and sequencing analysis method and all test results were validated by amniotic fluid testing at later stages of pregnancy. Out of 7 enrolled couples, who provided at least two blood samples (at least one week apart) for noninvasive CFTR testing, a result was obtained for 6 fetuses. Using the new hypersensitive method, all six couples (100%) received a correct diagnosis for the paternal allele as opposed to 3/6 (50%) when tested with the conventional strategy. Among 4 couples who provided just one early pregnancy blood draw for analysis, diagnosis was possible in one fetus, but only using the ultra-sensitive method. Thus, we describe a novel noninvasive CFTR screening method which demonstrates unprecedented fetal allele typing accuracy in the earliest stages of pregnancy.

RESUMEN

The optimal time to perform cryopreserved embryo transfer (CET) after a failed oocyte retrieval-embryo transfer (OR-ET) cycle is unknown. Similar clinical pregnancy rates were recently reported in immediate and delayed CET, performed after failed fresh OR-ET, in cycles with the gonadotrophin-releasing hormone (GnRH) antagonist protocol. This study compared outcomes of CET performed adjacently (<50 days, n = 67) and non-adjacently (≥50 to 120 days, n = 62) to the last OR-day of cycles with the GnRH agonist down-regulation protocol. Additional inclusion criteria were patients' age 20-38 years, the transfer of only 1-2 cryopreserved embryos, one treatment cycle per patient and artificial preparation for CET. Significantly higher implantation, clinical pregnancy and live birth rates were found in the non-adjacent group than in the adjacent group: 30.5% versus 11.3% (P = 0.001), 41.9% versus 17.9% (P = 0.003) and 32.3% versus 13.4% (P = 0.01), respectively. These results support the postponement of CET after a failed OR-ET for at least one menstrual cycle, when a preceding long GnRH-agonist protocol is used.

RESUMEN

Chromosomal abnormalities, sperm DNA damage, zona hardening, inadequate culture conditions, and suboptimal embryo development all play a significant role in the etiology of recurrent implantation failure. Evidence suggests that preimplantation genetic screening does not increase implantation or live birth rates. Comparative genomic hybridization array and analysis of single nucleotide polymorphisms could enable a more comprehensive screening of chromosomes. Assisted hatching may help to overcome zona hardening in selected cases. Optimal culture conditions and blastocyst transfer could contribute toward improving implantation and pregnancy rates. Novel embryo assessment and selection procedures, such as time-lapse imaging and metabolomics, may help in better evaluation of embryo quality and viability and help in selecting embryos with the highest implantation potential. The safety and efficacy of emerging treatment modalities should be evaluated in prospective randomized clinical trials before being applied in routine clinical practice.

RESUMEN

OBJECTIVE: To report a new fertility alternative for women with Turner syndrome, who are rendered infertile, by having their mothers freeze their own oocytes for the purpose of donating to their daughters when they are adults. DESIGN: Case report. SETTING: Academic teaching hospital. PATIENT(S): A 33-year-old healthy mother of three children; and her second child, a 6-year-old daughter recently diagnosed with Turner syndrome. INTERVENTION(S): Mother-to-daughter oocyte donation combined with oocyte vitrification. MAIN OUTCOME MEASURE(S): Number of cryopreserved oocytes. RESULT(S): After three cycles of ovarian stimulation, 30 oocytes were cryopreserved for the daughter's possible future use. CONCLUSION(S): The treatment option presented here opens the door for the banking of a mother's oocytes as a possible donation to a young daughter with a medical condition that leads to infertility, for her possible future use.

RESUMEN

OBJECTIVE: To compare rates of pregnancy loss after oocyte maturation in vitro (IVM), after IVF, and after intracytoplasmic sperm injection (ICSI). DESIGN: Retrospective comparative study. SETTING: University tertiary-care center for infertility. PATIENT(S): Women undergoing assisted reproductive technology in a single center. INTERVENTION(S): Oocyte maturation in vitro, IVF, or ICSI, as indicated. MAIN OUTCOME MEASURE(S): Biochemical pregnancy, clinical miscarriage, ectopic pregnancy, and late fetal loss. RESULT(S): There were 1,581 positive pregnancy tests (120 IVM, 849 IVF, and 612 ICSI). The biochemical pregnancy loss rate did not statistically significantly differ among the groups: 17.5% (21/120) after IVM, 17.0% (144/849) after IVF, and 18.0% (110/612) after ICSI. The clinical miscarriage rate after IVM was 25.3% (25/99), which was statistically significantly different compared with 15.7% (111/705) after IVF and 12.6% (63/502) after ICSI. However, the clinical miscarriage rates in women with polycystic ovary syndrome were statistically similar, at 24.5% (24/98) after IVM and 22.2% (18/81) after IVF. The ectopic pregnancy rates also were statistically similar: 1.0% (1/99) after IVM, 2.3% (16/705) after IVF, and 1.8% (9/502) after ICSI. The late fetal loss rates were similar as well: 1.0% (1/99) after IVM, 2.7% (19/705) after IVF, and 2.9% (14/502) after ICSI. There were no chromosomal abnormalities in the IVM group. CONCLUSION(S): There is a higher rate of clinical miscarriage after IVM when compared with IVF and ICSI. This appears to be related to polycystic ovary syndrome rather than to the IVM procedure.
