The effects of male age on semen parameters: analysis of 1364 men attending an andrology center

Although the effect of maternal age on fertility is well known, it is unclear whether paternal age also affects fertility. The aim of this retrospective study was to establish an association between the age of the individuals from Medellin, Colombia with semen volume, rapid progressive motility (a), total progressive motility (a + b) and concentration. We evaluated semen volume using a graduated tube, progressive motility using light microscopy (40×) and sperm concentration using a Makler Chamber. Semen samples were grouped according to age into three arbitrary groups (≤ to 30 years; between 31 and 39 years; and ≥ to 40 years). The semen volume, rapid progressive motility (a) and total progressive motility (a + b), concentration and total sperm count were found to be inversely related to age (p < 0.05). The reduction in semen parameters of 1364 men attending an andrology center was associated with increasing age of the individuals.

Pregnancy outcome in women with antiphospholipid syndrome and alloimmunity: a case report

CONTEXT: Patients with antiphospholipid syndrome and alloimmunity have poor pregnancy outcomes. Several diagnostic and therapeutic options exist for these disorders, although there is no consensus as to the best treatment. CASE REPORT: We present here the clinical course and treatment of a woman with a history of two miscarriages who joined our program 10 years ago and has been followed up ever since. After antiphospholipid syndrome and alloimmune failure were diagnosed, she was given preconceptional treatment using unfractionated heparin, aspirin, prednisone and lymphocyte immunizations. She delivered two premature babies in the following two pregnancies. At present both children are healthy and are attending school. The fifth pregnancy was unsuccessful, in spite of having undergone a similar but postconceptional therapeutic scheme. We discuss this case focusing on the pathogenic mechanisms and the therapeutic aspects of these disorders.
