Male fertility can be impaired by a multitude of factors. In addition to environmental and life style factors, such as stress, noise, smoking and overweight, diverse diseases can also have a negative effect on the ability to father a child and the hormone balance, particularly the testosterone level. In many diseases the currently available data do not go beyond observations of limited fertility. In this article the focus is on diseases in the treatment field of dermatology. Special attention is paid to chronic inflammatory and autoimmune skin diseases. Data from recent years show that the excessive inflammatory reaction that these diseases have in common, most probably also has an influence on fertility and interacts with the testosterone concentration in serum. In addition, the impact of hereditary skin diseases on male fertility is discussed, which can have a direct influence on the ability to father a child due to disruption of the hypothalamus-pituitary-gonad axis.

Objective: Several male factors have been reported to play a role in recurrent pregnancy loss (RPL). The aim of this study is to explore the relationship between semen parameters, sperm DNA fragmentation index (DFI) and RPL.
Method: A total of 1485 participants were recruited from a university hospital between April 2020 and August 2022.

Introduction: Pre-implantation testing (PGT) is often suggested by healthcare professionals (HCP) to parents of children with congenital adrenal hyperplasia (CAH) considering subsequent children. Despite this, some families choose to conceive naturally without genetic testing and intervention. The aims of this study were to explore fertility choices of couples with a child with CAH and the decision making process and perceptions behind these choices, and to explore the families' lived experiences with CAH and the couples' subsequent fertility journey.

Background: Over the past few decades, China has experienced significant demographic and epidemiological changes. The sharp decline in fertility and mortality rates has accelerated population aging, contributing to an increase in the prevalence of chronic diseases. The nutritional condition during early life is associated with the onset of chronic illnesses later in adulthood.

Reproductive senescence is common across taxa and females often show a predictable decline in fecundity after maturity. Attending to these age-dependent cues could help males make optimal mate choice decisions. Here, we examined reproductive senescence and male mate choice in the androdioecious mangrove rivulus (), where self-fertilizing hermaphrodites exist with rare males.

In vertebrates, glucocorticoids can be upregulated in response to both psychosocial and energetic stressors, making it difficult to identify the cause of elevated glucocorticoid concentrations when both types of stressors are present. This problem has been particularly challenging in studies of social dominance rank in wild animals. In contrast to glucocorticoids, thyroid hormone concentrations are largely unaffected by psychosocial stressors and therefore offer a better estimate of energetic challenges.
