Much of the planet is swimming in discarded plastic, which is harming animal and possibly human health. Once at sea, sunlight, wind, and wave action break down plastic waste into small particles: the microplastics (MPs). Currently, particular attention has been drawn to their effects on aquatic environments but the health risks, especially in mammals, are poorly known. These non-biodegradable materials can act as a vector for environmental pollutants, can be ingested by humans in food and water, and can enter and accumulate in human tissues with a possible risk for heath. Recent studies revealed the deleterious effects of MPs exposure in male reproduction and sperm quality, making them a potential hazard to reproductive success. This manuscript summarizes the main changes in sperm quality along the lifespan and the upcoming studies on the effects of MPs in male fertility in mammals.

To investigate the fertility status, pregnancy outcomes, and disease activity during and after pregnancy in patients with juvenile idiopathic arthritis (JIA) currently being followed up at an adult rheumatology clinic. This study included 141 adult patients diagnosed with according to the International League of Associations for Rheumatology criteria, who are now monitored at an adult rheumatology clinic. Data on demographics, disease characteristics, medication history, fertility status, and pregnancy outcomes were collected through medical records and patient interviews.

The production of spermatozoa, a process known as spermatogenesis, is primarily controlled by follicle-stimulating hormone (FSH) and luteinizing hormone (LH)-driven testosterone. LH acts on the Leydig cells, stimulating steroid production, predominantly testosterone, and activating critical inter-related spermatogenesis regulatory pathways. Despite evidence that exogenous gonadotropins containing LH activity can effectively restore spermatogenesis in males with hypogonadotropic hypogonadism, the use of these drugs to treat other forms of male infertility is the subject of an ongoing debate.

The study of the mechanism of oligoasthenospermia, which is a major cause of male infertility, has been the focus of research in the field of male reproduction. TAp73, a member of the p53 family of oncogenes, is endowed with tumor-suppressing activity due to its structural and functional homology with p53. It has been found that TAp73, plays a key role in spermatogenesis and maintaining male reproduction.

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.

: Male infertility is influenced by physiological factors like age, as well as lifestyle factors, including physical activity. However, the specific impact of sport activity on semen parameters, and thus on male fertility, remains unclear. Specifically, the aim of this systematic review is to evaluate how an intense regime of training may affect sperm parameters in professional and non-profession athletes.
