Non-random chromosome positioning in mammalian sperm nuclei, with migration of the sex chromosomes during late spermatogenesis. [PDF]
, 2005 Chromosomes are highly organized and compartmentalized in cell nuclei. The analysis of their position is a powerful way to monitor genome organization in different cell types and states.

Automated Sperm Immobilization for Intracytoplasmic Sperm Injection [PDF]
IEEE Transactions on Biomedical Engineering, 2011 Sperm immobilization is a requisite step in intracytoplasmic sperm injection (ICSI). Conventionally, sperm immobilization is performed manually, which entails long training hours and stringent skills. Manual sperm immobilization also has the limitation of low success rates and poor reproducibility due to human fatigue and skill variations across ...

Robotic ICSI (Intracytoplasmic Sperm Injection) [PDF]
IEEE Transactions on Biomedical Engineering, 2011 This paper is the first report of robotic intracytoplasmic sperm injection (ICSI). ICSI is a clinical procedure performed worldwide in fertility clinics, requiring pick-up of a single sperm and insertion of it into an oocyte (i.e., egg cell). Since its invention 20 years ago, ICSI has been conducted manually by a handful of highly skilled embryologists;

Intracytoplasmic sperm injection (ICSI) [PDF]
Human Reproduction, 2000 IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF.

Sperm retrieval techniques in azoospermic patients: PESA, MESA, TESA, TESE and MICROTESE [PDF]
Einstein (São Paulo), 2009 Azoospermia is defined as the absence of mature spermatozoa in semen analysis after centrifugation. The causes of azoospermia may be related to spermatogenesis defects and classified as non-obstructive azoospermia, or to the obstruction of the efferent ...

Intracytoplasmic sperm injection in Scandinavia [PDF]
Human Reproduction, 1996 Several Scandinavian clinics are now practising intracytoplasmic sperm injection (ICSI), and our data largely resemble that published from the Brussels group (Van Steirteghem et ai., 1993). In recent meetings, Scandinavian workers have come to some mutual decisions: (i) not more than two embryos will be replaced; (ii) recombinant follicle stimulating ...
