Rules for menopausal hormone therapy

The metamorphosis from perceived cardiovascular protection to perceived cardiovascular risk, a perception largely led by the Women’s Health Initiative study, has shifted the clinician’s risk/benefit decision-making away from prescribing menopausal hormone therapy (MHT) for menopausal symptoms. A more nuanced view of the literature and the greater availability of different modes of delivery and formulations of MHT should give the clinician the knowledge and confidence to prescribe appropriate MHT for the greater benefit of midlife health and cardiovascular safety.

The frog Aubria subsigillata is an edible species that is highly valued in the human diet in Benin. However, a strong rarefaction of the species due to its uncontrolled exploitation is observed in the wild. The 0.2 IU/g of Ovulin hormone administered intrafemorally enabled collection of gametes at 13 h in males and 27 h in females, and 172 eggs of 1 mg were incubated after 167 h. A. subsigillata reproduction goes through five phases: (1) selection of mature broodstock; (2) hormonal injection; (3) gamete collection; (4) in vitro fertilisation; and (5) incubation.

RD23132Clustering of spermatozoa examined through flow cytometry provides more information than the conventional assessment: a resilience to osmotic stress example

Superior identification of sperm subpopulations via cluster analysis with flow cytometry than with typical dot plots.

Evaluation of sperm quality in farm animals and humans is crucial to predict reproductive efficiency, yet conventional tests are not sufficient to predict fertility. Clustering sperm using individual data from flow cytometry analysis provides more information than typical dot plots, which could better predict sperm fertility and cryotolerance. Herein, combining cluster analysis with flow cytometry led to the identification of five sperm subpopulations with differences in cell volume and membrane integrity, whereas typical dot plots just allowed for the identification of three.

Illustration of differing seminal quality of rams associated with season and variants of the melatonin receptor gene.

Some variants of the melatonin receptor gene affect seasonal reproduction in sheep, but it is not clear how they affect males and their spermatozoa. This study explores the impact of two genetic variants of the melatonin receptor gene on ram seminal quality throughout the year. Results revealed that there is a detrimental effect on seminal quality, more pronounced during the reproductive season, depending on the variant carried, which highlights the potential of genotyping for optimal sire selection in breeding programs.

Impacts of melatonin on heat-stressed pregnant rabbits.

Melatonin administration (1 mg/kg body weight) during the first half of pregnancy of heat-stressed rabbits improved heat-tolerance capacity, sex hormone production, and fetal viability. These positive effects were subsequently associated with improved conception rate and kindling rate. Image by authors.

Chemical structure of Poly and per-fluoroalkyl substances and their impact on reproduction in humans and animals.

Poly- and perfluoroalkyl substances (PFAS) are widespread environmental contaminants that can accumulate in body tissues and cause adverse health outcomes. This article combines the perspectives of chemists, soil scientists, reproductive biologists, and health policy researchers, to summarise the issue of PFAS contamination and its specific impact on the reproductive health of all animals. It also highlights the important role scientists have to play in educating the public and policy makers on the complexity of the planetary health issues surrounding PFAS.

Diagram depicting effect of high-fat diet fed to pregnant rats on Sertoli cell function in offspring.

In rats, we tested whether a high-fat diet fed to mothers during pregnancy and lactation would affect Sertoli cell function in their adult offspring. Changes in transcription factors and proteins that control proliferation and apoptosis in germ cells suggest that the high-fat diet alters the balance between cell proliferation and apoptosis, potentially reducing sperm production.

High-magnification images of porcine oviductal extracellular vesicles adhering to spermatozoa.

We examined the tiny structures called extracellular vesicles that come from the fluid in pig uterus in order to understand how these vesicles change during the reproductive cycle of female pigs. Those from the late stages of the cycle seemed to have a strong connection with sperm and a possible key role in fertility. These vesicles regulate sperm function and interaction with oocytes, and they could potentially be used in fertility treatments to improve the chances of successful fertilisation.

Diagram showing potential alterations in the sperm parameters of obese men.

This review focuses on the potential impact of male obesity on sperm quality and function – a long-debated topic. The adverse effects of obesity on sperm parameters can significantly impair male and couple fertility, resulting in an increased necessity for fertility assistance among obese men. Furthermore, although more definitive research is needed, these individuals often experience poorer outcomes in assisted reproductive technologies. Image by João Ramalho-Santos.

Canine ovarian tissue during pro-oestrus, stained for aromatase.

In clinical practice, contraception in female dogs is traditionally achieved by surgical gonadectomy. As this method is discouraged by new animal welfare legislation in some parts of the world and is also related to several side effects, alternative possibilities for contraception are needed. Here, we report the distribution of aromatase in the canine ovary during different stages of the oestrous cycle. In-depth knowledge of oestrogen synthesis in the female dog is mandatory for targeted inhibition of oestradiol, possibly by the use of aromatase inhibitors. Photograph by M. P. Kowalewski.

Single Layer Centrifugation for different volumes of semen

Antimicrobial resistance is a global problem of monumental proportions, requiring radical action to stem its progress. One of the questionable uses of antibiotics is in semen doses used for artificial insemination, which may be contrary to current recommendations to restrict antibiotics for therapeutic purposes. This review describes some of the problems arising from antibiotic use in semen extenders and suggests some alternatives. Photographs by Jane M. Morrell.

Cross-section of an anuran sperm showing the position of mitochondria

The term ‘mitochondrial vesicle’ was first used in 2003 in a description of anuran sperm and persists to this day in the literature on assisted reproductive technologies (ART) for amphibians. In the present paper, we argue that the term ‘mitochondrial vesicle’ is inappropriate because the widely accepted definition of a ‘vesicle’ refers to an integral structure with an enclosing lipid bilayer/membrane.

Peripubertal ewe oviduct model of reduced fertilisation and poor embryo survival.

Declining fertility is an issue in multiple mammalian species, with around 15% of couples experiencing infertility. Differential expression of genes involved in inflammation, linked with altered steroid signalling in the oviduct, was observed in peripubertal ewes, a model of poor fertility. Ensuring that the oviductal environment does not become hostile to fertilisation and early embryo development may provide a novel approach to improve fertility, particularly in conditions associated with chronic low-grade inflammation.

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.

In 2018, Reproduction, Fertility and Development celebrated 30 years of publication and we recognised this milestone with this Collection of papers. Papers were selected based on hard data (citations and downloads) but we also chose papers that reflect other criteria: landmarks in important aspects of reproductive biology; recognition of an influential individual; showcasing the breadth of the journal’s output (species studied; the stages in the process of reproduction); balance between biology and technology; and the international nature of contributors to the journal.
