Outcome of intracytoplasmic sperm injection with and without polar body diagnosis of oocytes.

Objective: To compare the reproductive outcome of women undergoing intracytoplasmic sperm injection (ICSI) with or without polar body diagnosis of oocytes.

Design: Nonrandomized retrospective study.

Setting: University-based human genetic institute in collaboration with a private fertility center.

A high oocyte yield for intracytoplasmic sperm injection treatment is associated with an increased chromosome error rate.

Objective: To compare the chromosome error rate among oocytes from stimulated ovaries after retrieval of 1-5 oocytes, 6-10 oocytes, and >10 oocytes.

Design: Retrospective cohort study.

Setting: A university-based human genetic institute in collaboration with a private fertility center.

Sperm selection methods for intracytoplasmic sperm injection (ICSI) in andrological patients.

Purpose: To improve the chances of successful in vitro fertilization, spermatozoa have to be separated from semen before insemination. Therefore, sperm preparation methods are of great importance.

Methods: To obtain sufficient numbers of spermatozoa from patients with cryptozoospermia or severe OAT syndrome, only Minipercoll centrifugation and migration-sedimentation (MS) are practicable methods.

Pregnancy and birth after intracytoplasmic sperm injection with spermatozoa from a patient with tail stump syndrome.

Tail stump syndrome, which may be associated with primary ciliary dyskinesia, is also associated with morphological defects of the flagellum resulting in severe asthenozoospermia. Until recently, these morphological anomalies caused definite male infertility. Today, however, new methods such as micromanipulation techniques provide a rational therapy for this patient group.
