Female fertility is the foundation of the cow-calf industry, impacting both efficiency and profitability. Reproductive failure is the primary reason why beef cows are sold in the U.S. and the cause of an estimated annual gross loss of USD 2.8 billion. In this review, we discuss the status of the genomics, transcriptomics, and systems genomics approaches currently applied to female fertility and the tools available to cow-calf producers to maximize genetic progress. We highlight the opportunities and limitations associated with using genomic and transcriptomic approaches to discover genes and regulatory mechanisms related to beef fertility. Considering the complex nature of fertility, significant advances in precision breeding will rely on holistic, multidisciplinary approaches to further advance our ability to understand, predict, and improve reproductive performance. While these technologies have advanced our knowledge, the next step is to translate research findings from bench to on-farm applications.

Department of Agricultural and Environmental Sciences, University of Milan, via Celoria 2, 20133, Milan, Italy.
OsMAIL1 encodes for a rice protein of the Plant Mobile Domain (PMD) family and is strongly upregulated during floral induction in response to the presence of the florigens Heading date 3a (Hd3a) and RICE FLOWERING LOCUS T1 (RFT1). Although OsMAIL1 expression depends on the florigens, osmail1 null mutants do not show delay in flowering time, rather OsMAIL1 participates in ensuring successful reproduction. Indeed, when day temperatures reach 35 °C (7 °C higher than standard greenhouse conditions), osmail1 mutants show increased sterility due to abnormal pistil development with about half of the plants developing three styles topped by stigmas.

The anti-Müllerian hormone (AMH) is a granulosa cell-derived hormone that has been associated with female fertility and reflects the population of growing follicles. This study aimed to evaluate the average concentration of AMH in Lipizzaner mares, as well as to determine the relationship between AMH concentration and follicle number and size. We also investigated the relationship between the age of mares and their AMH levels.

Objective: To evaluate the impact of infertility and Medically Assisted Procreation (MAP) on female sexuality. Human sexuality presents a multifaceted complexity, shaped by diverse factors and individual intricacies. Infertility and assisted reproductive treatments entail a prolonged and arduous journey, amplifying pre-existing sexual dysfunctions and serving as a rigorous trial of the affected women's sexuality and the resilience of couples.

The circadian clock regulates physiological and biochemical processes in nearly every species. Sexual and reproductive behaviors are two processes controlled by the circadian timing system. Evidence supporting the importance of proper clock function on fertility comes from several lines of work demonstrating that misalignment of biological rhythms or disrupted function of the body's master clock, such as occurs from repeated shift work or chronic jet lag, negatively impacts reproduction by interfering with both male and female fertility.

The Ogura cytoplasmic male sterility (CMS) line of has gained significant attention for its use in harnessing heterosis. It remains unaffected by temperature and environment and is thorough and stable. The Ogura cytoplasmic restorer line of is derived from the distant hybridization of and , but it carried a large number of radish fragments into , because there is no homologous allele of the restorer gene in , transferring it becomes challenging.
