Modelling menstruation in animals that do not naturally menstruate is a challenge but not impossible. This review assesses the literature surrounding artificial menstruation in the common laboratory mouse. We noted that different models produce different menstruation-like events; the results highlight the importance of ovarian factors other than progesterone during menstruation. Researchers should select their chosen menstruation model carefully to ensure the model does not have negative impacts on the outcomes. Image created in BioRender, Rogers L (2025).

Genital infection represents a potential factor that could induce detrimental effects on male fertility. It has been suggested that lipopolysaccharide (LPS), a major component of Gram-negative bacteria, could have a negative effect on sperm quality. Our study made an attempt to explore the effect of LPS on human sperms and our data strongly suggest that LPS impairs mitochondrial membrane potential and leads to the activation of some pathways responsible for sperm apoptosis, notably in sperms from infertile men.

The growing interest in camels for racing, milk production and beauty competitions has generated enthusiasm to breed from genetically superior animals by using embryo transfer (ET). One of the major challenges of ET is getting large numbers of recipients synchronized with the donor for the day of transfer. However, it is possible to store embryos at 4°C for 2–3 days and addition of catalase to the cooling medium enhances overall pregnancy rates. This therefore reduces the need for such tight synchronization. Image by JA Skidmore.

Primary follicle in mouse ovarian section with both AMH-positive and AMH-negative granulosa cells.

For blood cancer survivors, a fertility preservation treatment generating eggs in culture by using their own cryopreserved ovarian tissue does not yet exist. This could be due to culture media missing crucial factors that exist in the circulation. We showed that mouse ovarian follicles do indeed grow better in culture supplemented with mouse serum. By identifying that there are additional factors in mouse serum that improve mouse ovarian follicle development, this paves the way to identify these molecules, which would likely be informative for humans.

Cat oocytes exhibit reduced competence when matured in vitro as compared to those matured within the ovarian environment. We sought to optimize a culture media that would increase developmental rates of immature oocytes through the use of an additional preliminary maturation step. While none of the additives chosen improved oocyte competence, we demonstrated the ability to hold oocytes for 24 h without a reduction in competence, an important finding for saving genetic material from endangered felids.

Diagram summarising potential stressors that may affect the sex of mammalian offspring.

This review explores how hormones may influence the sex of mammalian offspring. Researchers examined how natural hormones and hormonal treatments around fertilization and during early pregnancy could affect sex ratios. Although hormonal manipulations offer a potentially sustainable way to influence offspring sex, they remain less reliable than currently used methods such as sperm sorting or embryo selection.

Illustrated summary of sperm isolation techniques and their potential to improve equine fertility outcomes

Assisted reproductive technologies like artificial insemination help address equine infertility, but selecting high-quality sperm beforehand can further boost fertility rates. Traditional methods like centrifugation may damage sperm DNA, whereas newer techniques – microfluidics (using tiny fluid channels to filter healthy sperm) and electrophoresis (sorting sperm by electric charge) – offer gentler alternatives. Innovations like VetMotl™ and Felix™ enhance sperm selection, improving pregnancy outcomes. While cost of these devices remains a challenge, ongoing research could make these advancements more accessible for equine breeding. Illustration by Ashlee Medica.

A diagram showing the effect of high-fat diet on spermatogenesis in mice.

Obesity is a major health problem that can affect many parts of the body, including the reproductive system. This study examined how a high-fat diet can affect proteins potentially responsible for sperm production in mice. It was found that this diet led to changes in proteins called DNA methyltransferases, which can affect how other genes function through a process known as epigenetics. This suggests that obesity may contribute to male infertility by altering the epigenetic processes involved in sperm development. Image by authors using Biorender.com.

Diagram depicting known and potential roles of CCN proteins in ovarian function.

Infertility in women has been associated with increased ovarian fibrosis with age, and failure to ovulate an egg in conditions such as polycystic ovarian disease. Fibrosis can be increased by certain growth factors, such as the CCN proteins, which may also be involved in inflammatory processes leading to ovulation. This review summarized the known effects of CCN proteins in ovarian function, and proposes a role in ovulation. Image made in BioRender.

Sketch of light micrographs of non-gravid endometrium (left) and gravid endometrium (right).

Wallabies require rapid embryonic development as they give birth after a short pregnancy, immediately followed by ovulation. We analyzed and quantified differences between the gravid and the non-gravid uterus, which included a greater blood vessel area and increased surface area in the gravid endometrium and investigated the features ensuring the most efficient embryo-maternal exchange, such as polyploidy of trophoblast cells. However, these adaptations seem to be self-limiting making birth at the designated time inevitable. Image by Marie Muenzenberger.

Historically, melatonin has been seen as a pineal hormone that plays one essential role – the synchronisation of reproductive and other brain-controlled functions with changes in photoperiod. Often driven by the detection of melatonin receptors in non-brain tissues, it has become clear that melatonin plays a much wider variety of roles in the function of the testis, sperm, ovary, follicles, oocyte, embryo, placenta, fetus and mammary gland. This Collection presents this broader view of melatonin biology, and how the new concepts can be applied to livestock production.
