RESUMEN
OBJECTIVE: This study aimed to determine whether or not developmental potential impacts clinical outcomes, when good grade blastocysts from Days 5 and 6 were transferred in frozen embryo transfer (FET) cycles. METHODS: 654 women, including 460 (70.33%) on Day 5 and 194 (29.66%) on Day 6 were analyzed, in which 905 Day-5 and 274 Day-6 blastocysts were transferred. Only grade AA, AB, BA, BB quality and expansion grade between 3-6 (Gardner grading system) blastocysts survived and were included. RESULTS: The implantation rate was higher, 41.9% (379/905) in normal Day-5 compared to delayed Day-6 blastocyst transfers - 36.5% (100/274), but not significant (p=0.1). The clinical pregnancy rate was similar and not significant (p=0.4) in normal Day-5 (32.4%), compared to delayed Day-6 (35%). Miscarriage rates were higher in normal Day-5 (13.3%) compared to delayed Day-6 (6.3%) blastocyst transfers but were not significant (p=0.06). On the other hand, the biochemical pregnancy rate was significantly higher (p=0.001) in the delayed Day-6 blastocysts (16.7%) transfer group compared to patients with normal Day-5 (2.4%) blastocyst transfers. Two patients had ectopic pregnancies from the delayed Day-6 blastocyst transfer group. Live-Birth rates were significantly higher in Day-5 blastocysts compared to Day-6 (p=0.03). CONCLUSIONS: The developmental potential of embryos should not be considered a negative influence on pregnancy outcomes, especially good grade blastocysts vitrified on Days 5 and 6. Fully expanded blastocysts on Day-5 are considered similar in terms of outcomes to delayed Day-6 blastocysts; however, live-birth rates are significantly higher in Day-5 blastocysts.

Survivorship care is a major area of focus in the holistic management of childhood cancer with current knowledge and information almost exclusively from high-income countries. In this review, we summarize the state of scientific knowledge, service delivery, advocacy initiatives, and research efforts in this field in India. Twenty-one single-center studies published until today (20 in the last decade) confirm some of the well-documented issues in childhood cancer survivors and highlight the high prevalence of hepatitis B and hepatitis C infection in our survivors. Heterogeneity in methodology, outcome metrics, and quality precludes drawing further conclusions, and the ongoing multicenter Indian Pediatric Oncology Group study would address this. Besides the usual model of follow-up clinics in hospital settings, innovative models of service delivery led by not-for-profit organizations are being developed. Advocacy initiatives driven by survivors and support groups are also under way. All of these portend a promising future.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) widely known as COVID-19 was first reported in late December 2019, in China. Since then this novel coronavirus has spread throughout the world. Our return to normal life will not take long, for we are in a phase where the COVID-19 curve is stabilizing. ART services must return to operation, since infertility is also a disease and treatment has to start. Before resuming ART treatments, it is very important to consider local and national regulations. Change is mandatory, to set us back to successful ART treatment without compromising on quality, and to minimize the spread of COVID-19 among staff and patients; and for this we need to take measured and vigilant steps.

Occasionally, embryo transfer may be difficult, which is often because of anatomical position of the uterus or cervical stenosis. An alternative technique in such a scenario is the transmyometrial transfer of the embryos with the help of transvaginal ultrasound. Here, we describe the first case of successful embryo transfer through transmyometrial route leading to pregnancy and successful delivery in India.
RESUMEN
CONTEXT: Steady improvement in childhood cancer outcomes has led to a growing number of survivors, many of who develop long-term sequelae. There is limited data about these sequelae (including those related to fertility) on childhood cancer survivors from India. AIMS: We undertook a prospective pilot study on childhood cancer survivors from India to assess their gonadal function and fertility. SUBJECTS AND METHODS: A pediatric oncologist and a reproductive medicine specialist assessed 21 childhood cancer survivors. The risk of infertility was established using disease and treatment variables. Current status of puberty, sexuality, and fertility were assessed using clinical and biochemical parameters. Outcomes were correlated with risk group of infertility. Information was also ascertained on counseling with regards to risk of infertility. RESULTS: The cohort included 21 survivors (71% males) with a median age of 18 years who were off treatment for a median age of 7 years. Ten (48%) survivors were at low risk for infertility, 9 (43%) at medium risk and 2 (9%) at high risk. Gonadal dysfunction was seen in 3 (14%) survivors: 0/10 (0%) low risk, 1/9 (11%) medium risk, and 2/2 (100%) high risk. None of the survivors, who are at high risk or medium risk of infertility, received any counseling before treatment. CONCLUSIONS: This prospective pilot study of a cohort of childhood cancer survivors from India demonstrates a deficiency in the information provided and counseling of patients/families at the time of diagnosis with regards to the risk of infertility. Fertility outcomes of childhood cancer survivors were congruent with recognized risk groups for infertility. Future action points have been identified.
RESUMEN
BACKGROUND: Mature oocytes are prerequisite for achieving the process of in vitro fertilization. Human chorionic gonadotropin (hCG) is the standard trigger used for stimulating ovulation but is associated with ovarian hyperstimulation syndrome (OHSS). Gonadotropin-releasing hormone agonist trigger achieves oocyte maturation and lowers the incidence of OHSS, but it has limitations of higher pregnancy loss rate and miscarriage rates. Coadministration of both hormones is found to improve the pregnancy rates and the number of mature oocytes retrieved. We aimed to assess if the dual trigger is better than the conventional hCG in triggering oocyte maturation. METHODOLOGY: The study included 76 female patients aged 24-43 years who were randomly divided into two groups with 38 patients in each arm. The study included patients with antimullerian hormone (AMH) <4 ng/ml, antral follicle counts (AFCs)/ovary <12. The study excluded high responders-AMH >4 ng/ml and AFC/ovary >12 to avoid OHSS risk with hCG trigger. RESULTS: The study showed statistically insignificant differences between dual group versus hCG group in terms of the number of oocytes retrieved (10.0 ± 5.6 vs. 8.7 ± 5.0; P = 0.2816), the number of mature oocytes recovered (8.4 ± 5.0 vs. 7.2 ± 4.0; P = 0.2588), fertilization rate (5.9 ± 4.2 vs. 5.6 ± 3.3; P = 0.7390), and the number of usable embryos on day 3 (4.0 ± 3.0 vs. 4.0 ± 2.4; P = 0.8991). CONCLUSION: The dual trigger is equivalent to hCG in triggering oocyte maturation.
