Reproductive biomedicine is an exciting, fast-developing field. The main purpose is to help and care about the people with fertility problems and to enable a safe birth of a child. The approaches are different and involve experts of different specializations, from the clinical gynecology and obstetrics, andrology, histopathology, and pediatrics to more basic clinical embryology, reproductive biology, genetics, immunology, microbiology, biochemistry, and others. One of the most specialized and advanced approaches of reproductive medicine is assisted conception in couples with severe fertility disorders. By modern techniques of in vitro fertilization it is possible to treat severe female and male infertility. Many healthy children are born this way worldwide.

The main focus of this special issue will be on the new and established findings with a goal to better understand some new aspects of gametes, embryos, stem cells (including embryonic stem cells), gonads (ovaries, testicles) and other reproductive tissues (e.g., endometrium, oviducts, and placenta), and assisted conception procedures in humans and in the animal models. Special emphasis will be given to different basic aspects of diagnostics and treatment of human infertility. The special issue will be an important international forum for both basic and clinical researchers and has tendency to summarize the most recent and advanced developments, approaches, and ideas in the field. Potential topics include, but are not limited to:

• Reproductive biology (gametes, embryos, stem cells, and gonads and other reproductive tissues)
• Advanced proteomics/secretomics of gametes, embryos, stem cells, and gonads
• Transcriptome/genome/epigenetic studies
• Reproductive endocrinology
• Lab diagnostics of female and male infertility (biochemistry, microbiology, immunology, etc.)
• Assisted reproduction and in vitro fertilization, basics and clinical application
• Cryopreservation of gametes, embryos, and reproductive tissues for fertility preservation (infertility, cancer)
