Aims to highlight the changes occurred in the evolution of the fertility phenomenon in Romania, focusing on developments in the general fertility rate, total fertility rate, number of live births, and on the construction of specific indicators to reveal the source of demographic change. Several theories on the factors that may cause fertility decline it were outlined, underlining the presence of these factors during fertility dynamics in our country. After 1990, population decline may be explained by a close inter-relationship between economic theories (worsening economic conditions lead to decreased fertility) and the second demographic transition (postponement of births, fertility change model).

The Burro de Miranda is an endangered donkey breed. The dynamics of the immune system of the donkey's reproductive tract are essential to manage the fertility of these animals for the improvement and survival of the species. In mares, high numbers of immune cells infiltrating the endometrium promote endometrosis, which is still to be confirmed in jennies.

Ovarian aging significantly impacts female fertility, with mitochondrial dysfunction emerging as a key factor. This study investigated the effects of recombinant follicle-stimulating hormone (FSH) and luteinizing hormone (LH) on mitochondrial function and metabolism in aging female reproductive cells. Human granulosa cells (HGL5) were treated with FSH/LH or not.

The most severe form of male infertility is idiopathic non-obstructive azoospermia (NOA), a complete sperm absence in the ejaculate. We performed exome sequencing in the Croatian infertile brothers with NOA and found a variant in DMRT1 (Doublesex and mab-3 related transcription factor 1) gene that was further assessed by the EMSA assay and molecular dynamic simulations. We additionally screened for DMRT1 mutations in 1940 infertile men diagnosed with spermatogenic failure, 644 normozoospermic controls, and 105 females with primary ovarian insufficiency (POI) recruited to the GEnetics of Male INfertility Initiative (GEMINI) or Estonian Andrology (ESTAND) cohorts.

Over the years, the study of adult sex ratio is a topic that has gained attention for its impact on reproductive outcomes and aging across various insect species. However, there is still limited research focused on insects reared for food and feed production. To address this gap, this study aimed to evaluate the impact of different adult sex ratios on the reproductive dynamics and longevity of the superworm, Zophobas morio (F.

During copulation male insects transfer sperm and seminal fluids, including accessory gland proteins (Acps) to females, produced in the accessory glands (AGs). These Acps influence female behavior and physiology, inhibiting sexual receptivity, promoting ovulation and/or oviposition. The theory of ejaculate allocation postulates that production is costly; therefore, males strategically allocate ejaculates based on perception of sperm competition and quality and availability of females.
