The viability of deep-frozen aggregated mouse embryos.
Since the first successful aggregation of mouse embryos was reported by TARKowsKi,ii) many studies on chimera production have been carried out.S'6'7) Chimeras produced by the aggregation of early embryos have been widely used in experimental investigations of mammalian embryolegy and developmental genetics.4'9) Chimeric experimental animals have also been used to study some problems of human ge...
متن کاملO-23: Transfer of Blastocysts Derived from Frozen Thawed Cleavage Stage Embryos Improved Ongoing Pregnancy
Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...
متن کاملHuman pregnancy after transfer of intact frozen-thawed embryos.
Since the birth of the first baby as a result of in vitro fertilisation (IVF) in 1978, many clinics around the world have achieved pregnancies and births for their patients by using IVF and gamete intrafallopian transfer procedures. With the storage of excess embryos, multiple laparoscopies can be avoided; this has favoured the development of better cryopreservation techniques. In our clinic 8-...
متن کاملNonsurgical deep uterine transfer of vitrified, in vivo-derived, porcine embryos is as effective as the default surgical approach
Surgical procedures are prevalent in porcine embryo transfer (ET) programs, where the use of vitrified embryos is quasi non-existent. This study compared the effectiveness of surgical vs nonsurgical deep uterine (NsDU) ET using vitrified, in vivo-derived embryos (morulae and blastocysts) on the reproductive performance and welfare of the recipients. The recipient sows (n=122) were randomly assi...
متن کاملThe biopolitics of frozen embryos.
The unresolved debate about frozen embryos has left open the discussion on "what to do with them". There are only three ways to deal with frozen embryos: 1) to leave them frozen indefinitely; 2) to defrost and discard them and 3) to use them for research. In this paper, we suggest that the application of current scientific knowledge, instead of inappropriately referring to ethical principles or...
