BACKGROUND ICSI is currently the most commonly used assisted reproductive technology,
accounting for 70–80% of the cycles performed. This extensive use, even excessive, is partly …

BACKGROUND In natural conception only a few sperm cells reach the ampulla or the site of
fertilization. This population is a selected group of cells since only motile cells can pass …

Capacitation is a remarkable process whereby spermatozoa prepare themselves for
engagement with the oocyte. Although the existence of this process has been appreciated …

OBJECTIVE: To evaluate the role of hyaluronic acid (HA) for sperm selection before
intracytoplasmic sperm injection (ICSI). DESIGN: Three prospective studies. SETTING …

Assisted reproductive technologies (ARTs) utilize sperm sorting methods to select viable
sperm from the semen samples. Conventional sperm sorting techniques in current use are …

An integrated system combining a magnetically‐driven micromotor and a synthetized protein‐
based hyaluronic acid (HA) microflake is presented for the in situ selection and transport of …

Sperm selection in the female reproductive tract (FRT) is sophisticated. Only about 1,000
sperm out of millions in an ejaculate reach the fallopian tube and thus have a chance of …

Sperm selection is essential to assisted reproductive technology (ART), influencing
treatment outcomes and the health of offspring. The fundamental challenge of sperm …

Background The initial step in the diagnostic investigation of male infertility has been
traditionally based on the conventional seminal profile. However, there are significant …

Natural sperm selection in humans is a rigorous process resulting in the highest quality
sperm reaching, and having an opportunity to fertilize, the oocyte. Relative to other …
