Objective: To compare the clinical outcomes, including pregnancy rate, live birth rate, and miscarriage rate between vaginal progesterone Cyclogest suppository and Crinone vaginal progesterone gel as LPS in frozen-thawed embryo transfer in Intra-Cytoplasmic Sperm Injection (ICSI) cycles.

Methods: In this comparative retrospective chart review, 283 women who had frozen-thawed embryo transfer were assessed. The patients were divided into two groups based on the route of progesterone administration used as LPS.

Impact of blastocyst biopsy for preimplantation genetic testing on maternal and neonatal outcomes following single frozen embryo transfer cycles.

BMC Pregnancy Childbirth

January 2025

Assisted Reproduction Center, Northwest Women's and Children's Hospital, No. 73 Houzai Gate, Xincheng District, Xi'an, 710003, Shaanxi province, People's Republic of China.

Background: Up to now, a number of studies have explored the influence of blastocyst biopsy on maternal and neonatal outcomes, and the results have been somewhat inconsistent. Therefore, the aim of this study was to investigate whether blastocyst biopsy is associated with an elevated risk of hypertensive disorders of pregnancy (HDP) and other adverse perinatal outcomes during frozen embryo transfer (FET) cycles in singleton live births resulting from intracytoplasmic sperm injection (ICSI) in women aged ≤ 35 years.

Methods: A total of 1,008 women were involved in this study from January 2020 to June 2022, who underwent ICSI cycles and received single FET, leading to the birth of a live singleton newborn.

Correlation among blastocoel fluid DNA level, apoptotic genes expression and preimplantation aneuploidy.

Reprod Fertil

January 2025

M Bazrgar, Department of Genetics, Reproductive Biomedicine Research Center, Royan Institute for Reproductive Biomedicine, ACECR, Tehran, Iran., Tehran, Iran (the Islamic Republic of).

It is believed that aneuploid embryos release cell-free DNA (cfDNA) into the blastocyst cavity during the self-correction process through the apoptotic mechanism. This study aimed to develop less invasive methods for predicting ploidy status by investigating how ploidy status affects blastocoel fluid DNA (BF-DNA) levels and apoptotic gene expression as indicators of embryo viability. Human blastocysts were classified into three groups; Survivable Embryo (SE), Fatal Single and double Aneuploidy (FSDA), and Multiple Aneuploidy (MA) using array comparative genomic hybridization (array-CGH) by trophectoderm (TE) biopsy.

Effects of vaginal microbiota on fertilization outcomes in women with different infertility causes.

Microbiol Spectr

January 2025

School of Public Health, the Key Laboratory of Environmental Pollution Monitoring and Disease Control, Ministry of Education, Guizhou Medical University, Guiyang, Guizhou, China.

Unlabelled: Backed by advancements in technologies like microbial sequencing, many studies indicate that the vaginal microbiome is a key marker of female reproductive health. However, further studies are still needed to investigate the correlation between vaginal microbiota (VMB) and outcomes of assisted reproductive technology (ART). Therefore, this study compared the VMB of two types of infertile women undergoing fertilization (IVF) with normal control women during the implantation window period and investigated the effects of VMB characteristics on IVF outcomes.

Background: Endometrioma, a common manifestation of endometriosis, often indicates the severity of the disease. In vitro fertilization and embryo transfer (ET) are key therapeutic strategies for infertility associated with endometriosis. However, the optimal type of ET (frozen or fresh) and its impact on pregnancy success rates remain debated, with limited studies available.
