Food intake in rats was restricted so that the energy intake was 80 and 60% that of animals fed ad libitum. Although body weight gain was depressed, none of the other measurements taken (epididymal sperm count, fructolytic activity of spermatozoa, relative weights of the reproductive organs, concentration of fructose in coagulating glands and fertility in relation to females impregnated, conceiving and litter size) was affected.

Background/objectives: Both hyperandrogenism (HA) and vitamin D deficiency (VDD) can separately lead to impaired vascular reactivity and ovulatory dysfunction in fertile females. The aim was to examine the early interactions of these states in a rat model of PCOS.
Methods: Four-week-old adolescent female rats were divided into four groups: vitamin D (VD)-supplemented ( = 12); VD-supplemented and testosterone-treated ( = 12); VDD- ( = 11) and VDD-and-testosterone-treated ( = 11).

Undernutrition has increased worldwide in recent years and it is known that environmental factors to which individuals are exposed in early life can result in metabolic and reproductive changes that remain in adult life. In this context, the litter size expansion is a classic model used to induce undernutrition early in development. Thus, this study aimed to evaluate the effects of neonatal undernutrition induced by the litter size expansion on metabolic and reproductive parameters of female rats.

Stunting resulting from undernutrition is a significant global health challenge, particularly in developing countries, yet its underlying mechanisms and consequences remain inadequately understood. This study utilizes as an in vivo model to investigate the molecular basis of stunting. Due to the conserved nature of signaling pathways between and vertebrates, this organism serves as an effective model for studying growth disorders.

A global decline in male fertility has been reported, and climate change is considered a major cause of this. Climate change refers to long-term shifts in temperatures and weather patterns, and results from greenhouse gas emissions like carbon dioxide and methane that act as a blanket wrapped around the earth, trapping heat and elevating temperatures. Sad to say, the consequences of climatic variation are beyond the dramatic elevated temperature, they include cold stress, increased malnutrition, air pollution, cardiovascular diseases respiratory tract infections, cancer, sexually transmitted infections, mental stress, and heat waves.

Wernicke's encephalopathy, the acute phase of Wernicke-Korsakoff syndrome, is characterised as a triad of altered mental status, ocular signs and ataxia. Our patient presented with hyperemesis gravidarum, which is a rare aetiology of Wernicke's encephalopathy. The patient did not have any oculomotor abnormalities, which are more common and classically described in Wernicke's triad.
