Successful pregnancy with intracytoplasmic sperm injection after bacterial contamination of embryo culture in in vitro fertilization: a case report.

Background: Bacterial infection of embryo culture medium is rare but may be detrimental. The main source of embryo culture contamination is semen. Assisted reproduction centers currently lack consensus regarding the methods for preventing and managing embryo culture infection.

The importance of cytoplasmic strings during early human embryonic development.

During human fertilisation (IVF) treatments, embryologists attempt to select the most viable embryos for embryo transfer (ET). Previously, embryos were evaluated based on light microscopic morphological parameters. However, this is currently accomplished by morphokinetic analysis of time-lapse recordings.

Intracytoplasmic sperm injection does not improve the outcome of IVF treatments in patients with advanced maternal age or low oocyte number: A randomized controlled trial.

Introduction: Intracytoplasmic sperm injection (ICSI) was introduced to achieve fertilization in cases of severe male factor infertility. However, ICSI is often used in cases of non-male factor infertility, such as advanced maternal age or low oocyte number, but the clinical benefit of the method in these indications has not been proven.

Material And Methods: A prospective randomized study was conducted in a university clinic between 2018 and 2020.

[Is bacteriological screening of semen samples before in vitro fertilization treatment justified?].

The number of couples seeking assisted reproductive technologies is increasing worldwide. The question of whether routine bacteriological screening of semen is necessary during the investigation and treatment of infertility is controversial. The semen sample often contains bacteria even if the hygiene rules for collection are followed.
