The search for assisted reproduction techniques applied to the conservation and even the genetic improvement of wild species is becoming increasingly common. Regarding conservation of male gametes from wild animals, although current advances are focused on cryopreservation, the development of protocols for sperm refrigeration seems to be underrated, despite its various advantages and applications. Therefore, this review aims to highlight the importance of short-term conservation of sperm from wild mammals, report the development of state-of-the-art refrigeration protocols for both ejaculated and epididymal sperm, and evaluate the challenges and prospects of their application.

Traditional engagement with local governments often relies on financial and human resources from international or local partners, leading to direct implementation by organizations, which can hinder sustainability. While some organizations include sustainability indicators, few focus on transferring technical and financial ownership to governments. The Challenge Initiative (TCI) uses a phased coaching model-lead, assist, observe, and monitor-to build local government capacity for scaling family planning (FP) and adolescent and youth sexual and reproductive health (AYSRH) programs.

Pregnancy-associated changes in melanocytic nevi (MN), apart from size increase on the trunk, remain a topic of debate. We conducted the first prospective study to investigate dermoscopic changes in MN comparing pregnant with non-pregnant women on all body parts using a market-approved convolutional neural network (CNN). We included 25 pregnant and 25 non-pregnant women from Basel, Switzerland, who underwent standard skin cancer screenings and whose MN > 2 mm were digitally recorded and analysed by a CNN.

Background: This study aims to determine the impact of laptop and tablet use on total motile sperm count (TMSC) in men being investigated for assisted reproduction.
Methods: A cross-sectional study was conducted on 156 men attending a fertility clinic in Jamaica. Routine semen analyses were performed and parameters specific to TMSC assessed.

Cervical cancer (CC) is a prevalent gynecological malignancy. Increasing evidence suggests that circular RNAs (circRNAs) play a pivotal role in the pathogenesis of CC. However, the regulatory function of circ_ASH1L in CC remains elusive.

Aim: To evaluate if maternal serum soluble fms-like tyrosine kinase-1(sFlt-1) to placental growth factor (PlGF) ratio levels at term can anticipate the following adverse pregnancy outcomes: small for gestational age neonates; operative delivery for suspected fetal welfare compromise; and neonatal compromise.
Methods: A retrospective analysis of a single hospital database containing antenatal soluble fms-like tyrosine kinase-1 to placental growth factor (sFlt-1/PlGF) ratio results together with associated demographic, clinical and investigative information. Subjects with antenatal sFlt-1/PlGF measurements taken ≥37 weeks' gestation were analyzed.
