Study Arms (2)
idiopathic male infertility
* total of 30 male patients with idiopathic male infertility. * Semen samples will be collected from all patients Semen analysis will be examined after 2-5 days of sexual abstinence based on World Health Organization (WHO) (2010). * blood samples will be taken \&the following will be done Serum vitamin D level ,Serum calcium level ,Serum testosterone level ,luteinizing hormone (LH), and follicle-stimulating hormone (FSH), will be measured.
fertile male group
* total of 30 fertile male (as control) * Semen samples will be collected,Semen analysis will be examined after 2-5 days of sexual abstinence based on World Health Organization (WHO) (2010). * blood samples will be taken \&the following will be done Serum vitamin D level ,Serum calcium level ,Serum testosterone level ,luteinizing hormone (LH), and follicle-stimulating hormone (FSH), will be measured.
Interventions
-Semen samples will be collected from all patients Semen analysis will be examined after 2-5 days of sexual abstinence based on World Health Organization (WHO) (2010)
blood samples will be taken \&the following will be done Serum vitamin D level ,Serum calcium level ,Serum testosterone level ,luteinizing hormone (LH), and follicle-stimulating hormone (FSH), will be measured
Eligibility Criteria
total of 30 male patients with idiopathic male infertility and other 30 fertile male (as control) will be randomly recruited from the outpatient andrology clinic of the department at Assiut university hospital.
You may qualify if:
- infertile male patients without any detectable cause with normal clinical examination and abnormal semen parameters.
You may not qualify if:
- Cases with known etiology or apparent physical finding ,leukocytospermia, diminished testicular volume ,varicocele or an abnormal hormonal profile.
- couples with combined male and female factor will be excluded.
