Purpose: Prior sperm DNA fragmentation index (DFI) thresholds for diagnosing male infertility and predicting assisted reproduction technology (ART) outcomes fluctuated between 15 and 30%, with no agreed standard. This study aimed to evaluate the impact of the sperm DFI on early embryonic development during ART treatments and establish appropriate DFI cut-off values.

Methods: Retrospectively analyzed 913 couple's ART cycles from 2021 to 2022, encompassing 1,476 IVF and 295 ICSI cycles, following strict criteria.

Background: During mammalian spermatogenesis, the cytoskeleton system plays a significant role in morphological changes. Male infertility such as non-obstructive azoospermia (NOA) might be explained by studies of the cytoskeletal system during spermatogenesis.

Methods: The cytoskeleton, scaffold, and actin-binding genes were analyzed by microarray and bioinformatics (771 spermatogenic cellsgenes and 774 Sertoli cell genes).

Background: Estriol (E3) is a common estrogen responsible for regulating the female reproductive system, but excessive amount can pose health risks to humans and wild life. Therefore, sensitive and accurate detection of estriol level is crucial. A novel competitive ECL immunosensor based on a dual signal amplification strategy of AuNPs@GO@SmMoSe and Gd(MoO) was fabricated for ultrasensitive detection of estriol.

Objective: To study the sexuality of pregnant women after Assisted Reproductive Technology (ART).

Methods: This was a prospective multicenter study based on two questionnaires: the Female Sexual Function Index (FSFI) and the Couple Satisfaction Index 32 (CSI 32). Two groups were compared: pregnancies following ART and spontaneous pregnancies.

Background: Early pregnancy loss (EPL) occurs in 10%-15% of all pregnancies but remains an underrecognized and undertreated condition. In Canada, resources to support individuals and their partners facing EPL remain scarce despite a high burden of psychosocial sequelae. Digital health tools hold the potential to fill important gaps in reproductive healthcare.
