Study of nuclear and acrosomal sperm morphometry in ram using a computer-assisted sperm morphometry analysis fluorescence (CASMA-F) method.
2014
The aim of this study was to develop a new method that allows morphometric assessment of the sperm nucleus and acrosome in the ram using fluorescence microscopy and free software. The study was divided into three experiments. In the first experiment, semen smears from 20 ejaculates were fixed and labeled with a propidium iodide-pisum sativum agglutinin (PI/PSA) combination. Digital images of the sperm nucleus, acrosome, and whole sperm head were captured and analyzed using the ImageJ program. The computer-assisted sperm morphometry analysis fluorescence (CASMA-F) method used allowed the differentiation, capture, and morphometric analysis of most sperm nuclei, acrosomes, and whole heads with…
Use of Relief Contrast®Objective to Improve Sperm Morphometric Analysis by Isas®Casa System in the Ram
2013
The aim of this study was to develop a new method for morphometric assessment of the sperm head and acrosome in the ram. Ejaculates from 10 adult males were collected using an artificial vagina. For each ejaculate, 10 semen smears were prepared, air-dried and divided (in pairs) into the following five treatment groups: (i) washed in distilled water and allowed to dry without further processing (DRY); (ii) fixed in 50% methanol (MET); (iii) fixed in 2% glutaraldehyde (GLUT); (iv) fixed and stained with Hemacolor(®) (HEM) and (v) fixed and stained with SpermBlue(®) (SB). The prepared slides were examined with a 40 × Relief Contrast(®) objective (RC) and processed with ISAS(®) commercial softw…
