The present study, investigated some reproductive and fertility parameters in some wild populations, originating from the North Tunisia (4 populations of Medicago ciliaris and 3 populations of Medicago intertexta). Previous finding revealed that these species are genetically distinct and easily recognized by the number of flowers per inflorescence and pod dimensions. However, biometrical traits...

PURPOSE Many adolescent and young adult (AYA) cancer survivors place great importance on fertility. This study explored AYAs' discussions of fertility in the context of discussing their survivorship experiences. METHODS Secondary analyses of a qualitative study of young adult survivors of adolescent cancers ("AYA survivors") was performed using semistructured individual interviews and focus g...

The evaluation of any couple with infertility for any reason, including known post-vasectomy obstructive azoospermia, involves simultaneous evaluation of the female for her fertility potential with male evaluation. The goal of vasectomy reversal is to allow a couple to have a healthy child. In this overview, we will clarify that sperm retrieval with IVF is the most effective means for a couple ...

Little information exists about boar sperm chromatin quality and fertility within a commercial setting. The objective of this report is to provide information about boar sperm chromatin integrity and its relationship to fertility. The sperm chromatin structure assay (SCSA) was used retrospectively to characterize sperm from 18 sexually mature boars having fertility information. Boar fertility w...

Developmental environments are crucial for shaping our life course. Elements of the early social and biological environments have been consistently associated with reproduction in humans. To date, a strong focus has been on the relationship between early stress, earlier menarche and first child birth in women. These associations, found predominately in high-income countries, have been usefully ...

Recently presented evidence for nation states suggests that the long-standing negative relationship between socioeconomic development and fertility tends to turn positive at high levels of development. This article introduces the sub-national regional dimension to this debate. It focuses on Europe, which comprises a number of highly developed countries with comparatively high fertility rates. I...

BACKGROUND Many children treated for cancer are at risk of infertility, but for girls and prepubertal boys, all fertility preservation techniques remain experimental. We have assessed UK practice relating to information provision about the effects of cancer treatment on fertility and options for fertility preservation. METHODS Paediatric oncologists prospectively completed a data form for eac...

While the goal of African pastoralists is health and longevity of herd and household, some of their management strategies appear to counter this long-term goal. Pastoralists in the far north region of Cameroon, for example, do not always remove chronically sick animals from their herds, even though chronic diseases, such as brucellosis, are contagious and have the potential to cause fertility p...

While demography has made many valuable contributions to the analysis of contemporary demographic reversals, the discipline seems as far as ever from explaining the dynamics of fertility change. Commentaries on “populations” routinely link fertility control and small families with progress, modernity, and western values; in “traditional” societies, fertility regulation is left to chance, God, a...

Elder women suffer from low or loss of fertility because of decreasing oocyte quality as maternal aging. As energy resource, mitochondria play pivotal roles in oocyte development, determining oocyte quality. With advanced maternal age, increased dysfunctions emerge in oocyte mitochondria, which decrease oocyte quality and its developmental potential. Mitochondria supplement as a possible strate...
