PESA Some men find it hard to produce sperm in the ejaculate. This condition is called Azoospermia. This can be either due to problems in sperm production itself or due to obstruction to the flow of semen during ejaculation. Reproductive tract obstruction can be acquired – as a result of infection, trauma, iatrogenic injury which…

MACS SPERM

MACS SPERM MACS (Magnetic Activated Cell Sorting) is an immunomagnetic technique allowing the selection of those spermatozoa that do not show signs of cell damage or death (called apoptosis), and therefore maintain their entire DNA intact. Seminal quality is a crucial factor when it comes to achieving a pregnancy, since it affects both fertilization and…

IMSI

IMSI Intra-cytoplasmic Morphologically Selected Sperm Injection (IMSI) is a real-time method where sperms are selected before the microinjection takes place. This is done using an inverted microscope that is able to provide a much greater magnifying power (around 6,600 times) than those that are normally used in reproductive laboratories (400 times) to carry out the…

Blastocyst Culture

Blastocyst Culture In the IVF laboratory, after the egg retrieval procedure, fertilization is carried out by IVF (In-vitro fertilization) or by ICSI (intra-cytoplasmic sperm injection) and the resulting embryos are placed in an incubator for further development. The stages of development are as follows: The day of egg retrieval is considered as Day 0 (IVF…
