[Recurrent miscarriage and the quality of semen and sperm: a case-control study].

Objective: To analyze the relation between recurrent miscarriage and routine semen parameters.

Methods: We compared the semen parameters of normal healthy men with those of the spouses of recurrent miscarriage women through 1: 1 age-matched case-control study.

Results: Compared with the healthy controls, the men of the case group showed a significantly lower mean semen volume ([1.

[Infection of cytomegalovirus and herpes simplex virus and morphology of the infected spermatogenic cells in infertile men].

Objective: To study the infection of human cytomegalovirus (HCMV) and herpes simplex virus type II (HSV-I) and the morphological characteristics of the infected spermatogenic cells in the semen of infertile men.

Methods: We washed and concentrated the spermatogenic cells obtained from 83 semen samples of infertile men, extracted DNA and then screened HCMV and HSV-II by polymerase chain reaction (PCR). Immunocytochemistry (ICC) was used to detect the expression of correlative virus antigens of the positive semen cells, and the cytology smear was employed to observe the morphological changes of the spermatogenic cells under the microscope after cytology staining.

[The effects of dietetic hyperlipidemia on the development of testes and penises in male New Zealand rabbits].

Objective: To study the effects of dietetic hyperlipidemia on the development of testes and penises in male New Zealand rabbits.

Methods: The animal model of dietetic hyperlipidemia was established by feeding 36 male New Zealand rabbits which were divided into the test group (n = 20) and the control group (n = 16) at random with rich fat. The concentration of TC, TG, HDL-C as well as LDL-C was determined by using automatic biochemistry analyzer.
