Summary: Deer species in the Neotropical region are experiencing population declines and decreased genetic diversity due to rapid habitat loss and human activities. Assisted reproductive technology (ART) shows promise in advancing wildlife conservation efforts and maintaining genetic diversity in deer. Techniques such as in vitro embryo production (IVP) and proteomics are being utilized to better understand and address reproductive challenges facing Neotropical deer.

Summary: This nationwide cohort study examined the outcomes of assisted reproductive technology treatments in women using donor or partner sperm in Denmark from 2007 to 2017. The study found that the use of donor sperm was associated with higher odds of live birth after IUI treatments in women with male partners (aOR 1.48), single women (aOR 1.20), and women with female partners (aOR 1.46). However, there was no significant difference in live birth rates between women using donor and partner sperm after IVF treatments. The study highlights the importance of healthcare professionals attending to the individual needs and fertility issues of women seeking fertility treatments.

Summary: This prospective cohort study compared the neurodevelopmental outcomes of 12-month-old infants born through assisted reproductive technology (ART) and natural conception. The study found no significant differences in gross motor, adaptive behavior, language, and total development quotient scores between the ART and natural conception groups. However, the ART group had slightly higher social behavior development quotient scores, especially in male or singleton infants. These findings provide new information for evaluating the potential benefits and risks of ART.

Summary: This study found that an increased proportion of B. indicus genetics in crossbred cows resulted in reduced estrous response and pregnancy per artificial insemination after estrous synchronization. However, it did not lower the proportion of pregnant cows at the end of the breeding season. The interval from the beginning of the breeding season to pregnancy was extended as the proportion of B. indicus genetics in cows increased.

Summary: The Ovsynch protocol has been proven to increase pregnancy per artificial insemination (P/AI) in lactating dairy cows, compared to cows inseminated after a detected estrus. Implementing timed artificial insemination (TAI) programs has been an important factor in the significant improvement of reproductive performance in lactating dairy cows in the United States over the past 20 years.

Summary: The domestic buffalo, also known as water buffalo, is a globally significant livestock species. It includes two sub-species, the River buffalo and the Swamp buffalo. The River buffalo is a primary source of milk and meat in South Asia and supports high-value food production in Europe and the Americas. The Swamp buffalo is important for draft work and food in Southeast Asia and East Asia. The use of assisted reproduction, such as artificial insemination and embryo technologies, is becoming increasingly important for genetic improvement in buffaloes.

Summary: The primary objective of this randomized controlled experiment was to evaluate the insemination dynamic and reproductive performance of cows managed with a targeted reproductive management program. The study found that a TRM program designed to prioritize artificial insemination based on estrus detection during the voluntary waiting period was an effective strategy for improving reproductive outcomes.

Summary: The report provides data on the utilization, effectiveness, and safety of assisted reproductive technology (ART) globally in 2013, showing an increase in ART cycles and changes in trends such as a rise in the proportion of older women undergoing non-donor ART. Further efforts are needed to improve the quality and consistency of reporting ART data by registries.

Summary: This study examines the associations between different combinations of aerobic and muscle strengthening activity with mortality rates. The findings suggest that balanced levels of aerobic activity and muscle strengthening may reduce the risk of mortality.

Summary: A study using nationwide data from Denmark, Finland, Norway, and Sweden found that women who gave birth after assisted reproductive technologies (ART) did not have an increased risk of cardiovascular disease (CVD) compared to those who conceived without ART during a median follow-up of 11 years. Longer-term studies are needed to further investigate the association between ART and higher risk of CVD.

Summary: Assisted reproductive technology (ART) may affect fetal development through epigenetic mechanisms, leading to widespread differences in DNA methylation and variations in genes related to growth, neurodevelopment, and other health outcomes.

Summary: This study examined 227,297 artificial insemination acts conducted by 35 inseminators over a 4-year period in Turkey. The findings showed that the success rate of inseminators has an impact on conception rates. Inseminators with lower success rates should undergo retraining to prevent costs or losses on the farms.

Summary: This study examines the effects of intra-vaginal progesterone treatment on luteolysis, ovulatory follicle emergence, timing of estrus, and fertility in ewes. The results show that the timing of luteal regression is related to the emergence of ovulatory follicles, which in turn affects the timing of estrus. The relationship between the day of follicle emergence and luteal regression is influenced by treatment and cycling status. The study suggests two strategies to improve artificial insemination success: timed treatment with PGF2a and early treatment with eCG. Evaluation: 6 out of 10.

Summary: Some countries have age limits for donor offspring to access certain information after abolishing donor anonymity. In the UK and the Netherlands, there is a debate on whether to lower or abolish these age limits. This article presents arguments against lowering the age limits as a general rule, questioning the impact on the well-being of donor children, the isolation of the child from their family, and the contradiction with the practice of gamete donation.
