TL;DR: Overweight and obesity were associated with an increased prevalence of azoospermia or oligozoospermia, and whether weight normalization could improve sperm parameters should be evaluated further.
Journal ArticleDOI
Obesity leads to higher risk of sperm DNA damage in infertile patients
Charlotte Dupont,Céline Faure,Nathalie Sermondade,Marouane Boubaya,Florence Eustache,Patrice Clément,Pascal Briot,Isabelle Berthaut,Vincent Levy,Isabelle Cedrin-Durnerin,Brigitte Benzacken,Pascale Chavatte-Palmer,Rachel Levy +12 more
TL;DR: Using the terminal uridine nick-end labelling (TUNEL) assay, an increased rate of sperm DNA damage in obese men is observed, and the relationship between sperm DNA integrity and BMI is explored.
Journal ArticleDOI
Effects of cryopreservation on the meiotic spindle of human oocytes.
Jacqueline Mandelbaum,O. Anastasiou,Rachel Levy,J.F. Guérin,V. de Larouzière,Jean-Marie Antoine +5 more
TL;DR: Fundamental studies in humans, showing good preservation of cell structures after freeze-thaw procedures opened the way to new successful clinical trials with embryos derived from cryopreserved mature oocytes, demonstrating at least the feasibility of this technique.
Journal ArticleDOI
Sperm parameters and male fertility after bariatric surgery: three case series.
Nathalie Sermondade,Nathalie Massin,Florence Boitrelle,Jérôme Pfeffer,Florence Eustache,Christophe Sifer,Sébastien Czernichow,Rachel Levy +7 more
TL;DR: Intacytoplasmic sperm injection with fresh spermatozoa after male bariatric surgery can be successful, as demonstrated here, where clinical pregnancies were obtained for two out of the three couples and the alterations of spermatogenesis were reversible 2 years after the surgical procedure.
Journal ArticleDOI
Obesity and Increased Risk for Oligozoospermia and Azoospermia
TL;DR: In this article, the level of evidence on the association between body mass index (BMI) and sperm count through a systematic review and meta-analysis was updated. But, the relationship between BMI and sperm parameters remains controversial.
