  • The success of clinical IVF was initially compromised by sub-optimal culture conditions, resulting in impaired embryo development (1–6) and a subsequent loss of viability. However, research during the past 10–15 years has resulted in the development of more physiological and effective culture media capable of maintaining the viability of the developing embryo (7–10). This in turn has resulted in an increase in implantation rates and a decrease in the number of pregnancies lost. Furthermore, more suitable culture conditions produce embryos more able to survive cryopreservation (11). ...

  • Since its first description by Steptoe and Edward, IVF gained popularity among both doctors and patients. There is many studies on assisted reproduction and they cover most of the related technical, laboratory as well as clinical aspects. To write a book on assisted reproduction nowadays seems very difficult due to a wide plethora of related papers and well-illustrated books. This small-sized book aims at refinement of some already known points of practical importance in infertility management particularly ART.

  • We have previously reported a mouseRnf33⁄Trim60gene that is temporally expressed in the pre-implantation embryo. TheRnf33structural gene is com-posed of a short noncoding exon 1 and an intronless coding exon 2. In the present work,Rnf33was shown to be expressed in the mouse testis and in the testicular cell lines TM3 and TM4.

  • Surrogacy is an agreement in which a woman becomes pregnant and gives birth to a child for someone else. Surrogacy can be paid or unpaid, and often involves a legal contract in which the surrogate gives up parental rights to the child she births. If the surrogate’s own eggs are used through alternative insemination or IVF, she is known as the “genetic surrogate.” If embryos are created using another woman’s eggs and implanted in the surrogate, she is known as the “gestational surrogate” and has no genetic tie to the child. Hiring a surrogate in the US can...
