Results: Acrosome formation can be divided into four stages: Golgi-phase, cap-phase, acrosome-phase and maturation-phase. In the past 10 years, with gene targeting technology, more than ten genes were...

Globozoospermia is a common reproductive disorder that causes male infertility in humans, and the malformation or loss of acrosomes is the prominent feature of this disease. Although the acrosome is thought to be derived from the Golgi apparatus, the detailed molecular mechanisms remain unclear. GM130 is a cis-side localized Golgi matrix protein,whereas the physiological functions of this prote...

Klinefelter syndrome and Y-chromosomal microdeletion analyses were once the only two genetic tests offered to infertile men. Analyses of aurora kinase C (AURKC) and DPY19L2 are now recommended for patients presenting macrozoospermia and globozoospermia, respectively, two rare forms of teratozoospermia particularly frequent among North African men. We carried out genetic analyses on Algerian pat...

The objective of this study was to determine the aneuploidy level in spermatozoa in two men with globozoospermia. Sperm nuclei were analysed by fluorescence in-situ hybridization (FISH) in two infertile males with globozoospermia. Dual FISH for chromosomes 7 and 9, 13 and 21, and triple FISH for chromosomes X, Y, and 18 was performed. The main outcome measured was meiotic segregation difference...

Background: Male infertility is a Multifactorial syndrome encompassing a wide variety of disorders. In more than half of infertile men, the cause of their infertility is unknown (idiopathic) and could be congenital or acquired. Globozoospermia, also called round-headed spermatozoa, is a rare disease with incidence< 0.1% among male infertile patients. The most prominent feature of globozoospermi...

objective: globozoospermia is a rare syndrome with an incidence of less than 0.1% among infertile men. researchers have recently identified a large deletion, about 200 kbp, encompassing the whole length of dpy19l2 or mutations in spata16 and pick1 genes associated with globozoospermia. the aim of this study was to analyze the dpy19l2 gene deletion using polymerase chain reaction technique for t...

The successful outcome of intracytoplasmic sperm injection (ICSI) with round-headed spermatozoa (globozoospermia) and ionomycin assisted activation oocytes is reported. A 30-year-old man with 100% globozoospermia underwent ICSI treatment. Real-time Polymerase Chain Reaction (PCR) detection indicates that the patient was DPY19L2 homozygous deletion. Nine metaphase II oocytes were injected with r...

A man with globozoospermia was treated in our in-vitro fertilization-intracytoplasmic sperm injection (ICSI) programme. In the treatment cycle, 24 oocytes were collected from his wife. All the oocytes were at metaphase II stage. The semen sample produced on the day had a normal sperm count, good motility, but with 100% globozoospermia. All oocytes were injected with randomly selected spermatozo...

We here report a successful pregnancy and healthy childbirth obtained in a case of total globozoospermia after intracytoplasmic morphologically selected sperm injection (IMSI) without assisted oocyte activation (AOA). Two semen analyses showed 100% globozoospermia on classic spermocytogram. Motile sperm organelle morphology examination (MSOME) analysis at ×10,000 magnification confirmed the rou...
