From Sterility to Fertility

Selection for Self-fertility and Self-fertility in Alfalfa as a Tool for Breeding Strategy Assessment

Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Cultivar development in alfalfa relies on heterosis, that has been mainly exploited by intercrossing selected clones from diverse gemplasm sources; an alternative way was proposed, based on developing double cross cultivars obtained by crossing clones selected for self-sterility, propagated by somatic seed. A differen...

Access to fertility services by transgender persons: an Ethics Committee opinion.

This statement explores the ethical considerations surrounding the provision of fertility services to transgender individuals and concludes that denial of access to fertility services is not justified.

Fertility preservation and reproduction in cancer patients.

Cancer treatment often results in reduced fertility. Cancer patients should be informed of options for fertility preservation and future reproduction prior to cancer treatment. Reproduction in the context of cancer raises a number of ethical issues related to both patient and offspring welfare.

Inability of mature oocytes to create functional haploid genomes from somatic cell nuclei.

Informing offspring of their conception by gamete donation.

The Ethics Committee supports disclosure from parents to offspring about the use of donor gametes in their conception. The merits of further disclosure are discussed, and suggestions are made for policies for programs and sperm banks.

A novel mouse chromosome 17 hybrid sterility locus: implications for the origin of t haplotypes.

The effects of heterospecific combinations of mouse chromosome 17 on male fertility and transmission ratio were investigated through a series of breeding studies. Animals were bred to carry complete chromosome 17 homologs, or portions thereof, from three different sources-Mus domesticus, Mus spretus and t haplotypes. These chromosome 17 combinations were analyzed for fertility within the contex...
