In two fruit fly species, in vivo observations of competing sperm reveal how differences in sperm size, female behavior and reproductive architecture promote retention of same-species sperm. Sexual selection continues after mating and may play an important role in speciation.

The objective of this review is to evaluate the contributions of Artificial Intelligence (AI) to Assisted Reproductive Technologies (ART), focusing on its role in enhancing the processes and outcomes of fertility treatments. This study analyzed 48 relevant articles to assess the impact of AI on various aspects of ART, including treatment efficacy, process optimization, and outcome prediction. The effectiveness of different machine learning paradigms-supervised, unsupervised, and reinforcement learning-in improving ART-related procedures was particularly examined.

During fertilization, a series of reactions between the eggs and spermatozoa proceed predominantly in a species-specific manner. The molecules mediating these species-specific reactions remain unknown except in a few organisms. In this study, we focused on two species belonging to the phylum Nemertea, and , and explored molecules involved in species-specific interactions between gametes.

In male animals, spermatogonia in testes differentiate into sperm, one of the most diverse cell types across species. Despite the evolutionary retention of key genes essential for spermatogenesis, the extent of their conservation remains unclear. To explore the genetic basis of spermatogenesis under strong selective pressure, we compare single-cell RNA sequencing (scRNA-seq) datasets from the testes of humans, mice, and fruit flies.

Complexity and reproductive plasticity are very well-known characteristics of anurans. The group is being continuously explored taxonomically and phylogenetically, which leads to a great potential diversity not yet uncovered. This is particularly evident due to the lack of investigation regarding species-specific traits, even the ones well distributed in the lineages as polyandry.

The evolution of green plants from aquatic to terrestrial environments is thought to have been facilitated by the acquisition of gametangia, specialized multicellular organs housing gametes. Antheridia and archegonia, responsible for producing and protecting sperm and egg cells, undergo formative cell divisions to produce a cell to differentiate into germ cell lineages and the other cell to give rise to surrounding structures. However, the genes governing this process remain unidentified.
