Although numerous articles have shown intracytoplasmic sperm injection and in vitro fertilization to be correlated with increased risk of disease, a few works have been published on the risks associated with artificial insemination. Meanwhile, questions about the possible causes underlying these correlations have remained in the background. The main objective of this work is not to review the risks associated with artificial insemination, but rather to describe how developmental processes may be affected by these techniques. Thus, we offer a theoretical framework for understanding the possible causes that underlie the correlation between low-complexity or milder techniques and offspring health outcomes.

Background: The safety and effectiveness of short-term insemination remain a subject of controversy. This study aims to investigate the impact of short-term insemination on both embryo quality and pregnancy outcomes and whether it is necessary to apply short-term insemination to all patients underwent in vitro fertilization (IVF).
Methods: A retrospective analysis was conducted on 3,496 patients from two centers over the period January 2016 to December 2022.

Graphene oxide (GO) has been extensively studied for its diverse biomedical applications, including drug delivery, imaging, and tissue engineering. Silymarin, as a flavonoid complex derived from the milk thistle plant, has recently shown potential health benefits, particularly concerning reproductive health. This study aims to evaluate the effects of GO and silymarin supplementation, both individually and in combination, on the characteristics of frozen-thawed ram sperm.

The objectives of this study were: (i) to evaluate the associations between postpartum health disorders, relative increase in walking activity (RIWA) and expression of behavioral estrus intensity captured by pedometers; (ii) to assess associations between RIWA and pregnancy in cows submitted to timed artificial insemination (TAI). Lactating dairy cows (n = 881) were enrolled in the study. Cows were submitted to a 5d TAI protocol with insertion of a progesterone device.

Sperm motility is the prime functional attribute for semen quality and fertility of the bull. However, the bull's age directly affects the semen quality, and the bull's fertility and productive life decline with age. Even though research on age has been conducted in the past, it is still unclear how old a bull should be maintained at artificial insemination centers.

Artificial insemination (AI), as an efficient assisted reproduction technology, can help the livestock industry to improve livestock and poultry breeds, optimize production performance and improve reproductive efficiency. AI technology has been widely used in pig production in China, but boar fertility affects the effectiveness of AI, and more and more studies have shown that there are significant differences in the fertility of boars with similar semen quality indicators. Therefore, this study aimed to identify biomarker molecules that indicate the level of boar fertility, which is important for improving the efficiency of AI.
