Despite the advent of ICSI, cases of total fertilization failure (TFF) often lead to cycle cancellation with limited diagnostic and therapeutic strategies currently available. We report on the case of an infertile couple who failed to conceive after

Efficient integration of functional genes is an essential prerequisite for successful gene delivery such as cell transfection, animal transgenesis, and gene therapy. Gene delivery strategies based on viral vectors are currently the most efficient. Ho

We have developed a method that effectively removes all of the perinuclear materials of a mouse sperm head, including the acrosome, plasma membrane, perinuclear theca, and nuclear envelope. By injection of a single purified sperm head into a metaphas

There are cases in which the 1-day-old unfertilized oocytes after IVF, or in vitro matured oocytes obtained from denuded immature oocytes after ICSI, are used clinically. We investigated the morphological change of metaphase II spindle and chromosoma

We identified a previously uncharacterized gene, spermatid maturation 1 ( Spem1 ), encoding a protein exclusively expressed in the cytoplasm of steps 14–16 elongated spermatids in the mouse testis. This protein contains no known functional domains

Fertilization failure (complete fertilization failure or low fertilization rates) after intracytoplasmic sperm injection (ICSI) can occur in rare cases. In the majority of these cases, the unfertilized oocytes are inactivated. Assisted oocyte activat

Cryopreservation of male germ cells is a strategy to conserve animal species and strains of animals valuable to biomedical research. We tested whether mouse male germ cells could be cryopreserved without cryoprotection by simply freezing epididymides

In mice and humans, a normal offspring can be obtained by injecting a single spermatozoon into an oocyte, the process called intracytoplasmic sperm injection (ICSI). When three or more mouse spermatozoa with intact acrosomes were injected into indivi
