Normal live birth after testicular sperm extraction and intracytoplasmic sperm injection in variant primary ciliary dyskinesia with completely immotile sperm and structurally abnormal sperm tails

We present a case of variant primary ciliary dyskinesia with complete asthenozoospermia and reduced respiratory function. Testicular sperm extraction was used to retrieve improved-quality sperm, and a healthy child was achieved with the use of intracytoplasmic sperm injection.

Fertilization outcome could be regulated by binding of oviductal plasminogen to oocytes and by releasing of plasminogen activators during interplay between gametes

Plasminogen is present in the oviductal fluid. Plasminogen and plasminogen activators are present in oolemma and zona pellucida of matured oocytes. After IVF, the immunoreactivity for plasminogen and its activators in oocytes decreases. Presence of plasminogen in the IVF medium decreases polyspermy rates.
