Assisted reproductive techniques in latin america: the latin american registry, 2017

Conclusions: The number of initiated cycles slowly increases. Frozen embryo transfers, blastocyst transfers and SET are also increasing. Our data shows that especially in young women and oocyte recipients, when there is more than one blastocyst for transfer, elective SET should be the rule.

Purpose of review An update on the latest advances in fertility preservation for transgender women, with an emphasis on the attitudes, access, and techniques. Recent findings With recent warming in perception toward transgendered individuals, fertility preservation services are becoming increasingly available. Although new multidisciplinary transgender clinics are appearing in North America, a 2018 report shows a referral rate for fertility preservation of only 13.5%. Despite interest in child rearing, uptake of fertility preservation is still low as patients are transitioning at increasingly younger ages. Sperm cryop...

Abstract The use of intracytoplasmic sperm injection (ICSI) has been a major breakthrough in the treatment of male infertility. Even patients with non-obstructive azoospermia (NOA) may benefit from the ICSI technique to father a child as long as spermatogenesis is present. There are several techniques to recover testicular sperm in patients with NOA. However, retrieval of spermatozoa is unfortunately still only successful in a subset of patients with NOA, and the most superior sperm retrieval method is still under debate. A more recent technique, microdissection testicular sperm extraction (MD-TESE) with an operat...

rua J Abstract Assisted reproductive technologies involving the use of spermatozoa and eggs for in vitro fertilization (IVF) have come as the solution for many infertile couples to become parents. However, in some cases, the use of ejaculated spermatozoa delivers poor IVF performance. Some studies have suggested the use of testicular spermatozoa in severe male infertility cases, but no guidelines regarding their utilization are currently available. In the present study, we found the mRNA protamine 1/protamine 2 (P1/P2) ratio to be a valuable biomarker of poor sperm function that could be used as a diagnostic key f...

Both 2-D and 3-D transvaginal ultrasonography are effective imaging modalities for assessment of ovarian reserve. Our aim was to compare both modalities in assessment of ovarian reserve of women undergoing in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI). Fifty women were scheduled according to their menstrual cycle to be examined by both 2-D and 3-D transvaginal ultrasonography. We found that the average time for computerized analysis of the 3-D ultrasound data was significantly shorter than that for analysis of the 2-D ultrasound data, for both total antral follicle count and ovarian volume.

AbstractWith the increased rate of stable remission after gonadotoxic cancer treatment, new methods of fertility preservation are required in order to provide the best possible care for oncological patients. Here, we report an original case of euploid blastocyst cryopreservation after in vitro maturation of ovarian tissue oocytes (OTO IVM). Thirty-three oocytes were obtained from the ovarian tissue after ovariectomy in the breast cancer patient. Six out of 12 matured oocytes fertilized successfully and 3 blastocysts were formed. Genetic investigation for mutations associated with this type of malignancy found that the pati...

AbstractPurposeTo compare the efficacy of mild ovarian stimulation protocol and conventional controlled ovarian stimulation (COS) protocol for poor ovarian response (POR) patients undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI).MethodsThis single-center prospective randomized controlled trial conducted from September 2013 to September 2015, including 191 patients who met the Bologna criteria of POR. Ninety-seven patients allocated to the mild ovarian stimulation group (MS group) were stimulated according to the letrozole/antagonist protocol, while 94 patients in the controlled ovarian stimul...

Abstract This paper is a retrospective analysis of the sole transfer of monopronucleated zygotes (1PN) embryos both in in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) to determine the value of transferring embryos formed from 1PN. In fresh cycles, 1PN cleavage-stage embryos (1PN cleavage fresh) were transferred. In frozen-thawed cycles, 1PN blastocyst-stage embryos (1PN blast frozen) were transferred. We used comparison groups: for fresh cycles, 2PN cleavage-stage embryos (2PN cleavage fresh) were transferred; and for frozen-thawed cycles, 2PN blastocyst-stage embryos (2PN blast frozen) we...

Morphology is the traditional method of selecting embryos for transfer and sperm for intracytoplasmic sperm injection. However, this approach has its limitations. Use of other embryo selection methods, such as time-lapse morphokinetic imaging and preimplantation genetic testing for aneuploidy, as well as diagnostic and selection techniques for sperm including sperm deoxyribonucleic acid fragmentation index and intracytoplasmic morphologic sperm injection, have been used with varying degrees of success.
