Andrology: Successful fertilization and establishment of pregnancies after intracytoplasmic sperm injection in patients with globozoospermia
Abstract
Globozoospermia or round-headed spermatozoa is a rare type of teratozoospermia where the acrosome is absent resulting in male infertility with no known therapy. A few studies have shown that round-headed spermatozoa cannot bind to or penetrate the zona pellucida, and no normal fertilization has been observed in in-vitro fertilization (IVF) after insemination of human oocytes with round-headed spermatozoa. In this study, the fertilization capacity of round-headed spermatozoa after intracytoplasmic sperm injection (ICSI) into human oocytes has been examined. In pre-clinical experiments, 45 oocytes were injected; 41 oocytes were intact after injection, 15 oocytes were fertilized normally, and 13 of these 15 oocytes developed further in vitro. ICSI was carried out in 11 treatment cycles of seven infertile couples with globozoospermia. Normal fertilization and embryo transfer occurred in four cycles (three patients). Positive serum human chorionic gonadotrophin was observed in three cycles (two patients); one patient had a pre-clinical abortion and the other patient became pregnant twice; the first pregnancy was ectopic and the second pregnancy is a twin pregnancy which is currently at 16 weeks of gestation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
