Relation Between Sperm Binding Ability to Hyaluronic Acid With Protamine Deficiency and DNAFragmentation

Chromomycin A3 Staining Indicates Sperm Protamine Deficiency

Chromomycin A3 binds to DNA and Protamine -deficient spermatozoa look bright yellow,whereas normal spermatozoa appear dull yellow.

P-62: Damage to Sperm DNA and Protamine Deficiency Induced by Risperidone in NMRI Mice

Background: Antipsychotic medication use is a common cause of hyperprolactinemia that shown to have adverse effects on male fertility. Risperidone is a combined serotonin/dopamine receptor antagonist that can cause elevations in prolactine level. Its mechanism of cytotoxic effects on testicular germ cells is not fully understood. In the present study we sought to elucidate the impact of risperi...

Relationship between sperm protamine deficiency and apoptosis in couples with unexplained repeated spontaneous abortions

BACKGROUND Etiology of more than half of Recurrent Spontaneous Abortion. The etiology of more than 50 percent of Recurrent Spontaneous Abortions (RSA) cases has been remained unexplained. It is supposed that RSA may have "paternal effect" due to supply 50% of embryonic genomic content by male gamete. OBJECTIVE The aim of present study was to evaluate the role of sperm apoptosis and protamine ...

Sperm parameters, protamine deficiency, and apoptosis in total globozoospermia

BACKGROUND Globozoospermia is a severe form of teratozoospermia (incidence < 0.1%) in infertile men that is characterized by round headed sperm and acrosomeless in semen. OBJECTIVE To compare the semen parameters, protamine deficiency, and apoptosis in ejaculated spermatozoa between globozoospermic and normozoospermic men. MATERIALS AND METHODS Thirty six semen samples were divided into two...
