BACKGROUND Poor sperm quality can negatively affect embryonic development and IVF outcome. This study is aimed at investigating the influence of various lifestyle factors on semen quality according to MSOME (motile sperm organelle morphology examination) criteria. METHODS 1683 male patients undergoing assisted reproductive technologies (ART) in our clinic were surveyed about their age, BMI (b...

background: sperm vitrification is a technique of ice and cryoprotectant free cryopreservation by direct plunging of sperm suspension into liquid nitrogen (ln2). the aim of this study was to investigate the influence of cryoprotectant free-vitrification on human sperm fine structure by msome technology and the fertility potential by zona binding assay (zba). methods: 20 normo-ejaculates were pr...

We here report a successful pregnancy and healthy childbirth obtained in a case of total globozoospermia after intracytoplasmic morphologically selected sperm injection (IMSI) without assisted oocyte activation (AOA). Two semen analyses showed 100% globozoospermia on classic spermocytogram. Motile sperm organelle morphology examination (MSOME) analysis at ×10,000 magnification confirmed the rou...

BACKGROUND This study aimed to investigate the influence of age on sperm quality, as analysed by motile sperm organelle morphology examination (MSOME). METHODS Semen samples were collected from 975 men undergoing evaluation or treatment for infertility. Sperm cells were evaluated at 8400× magnification using an inverted microscope equipped with Nomarski (differential interference contrast) op...

Motile sperm organelle morphology examination (MSOME) involves the use of differential interference contrast microscopy (also called Nomarski contrast) at high magnification (at least 6300x) to improve the observation of live human spermatozoa. In fact, this technique evidences sperm head vacuoles that are not necessarily seen at lower magnifications - particularly if the vacuoles are small (i....
