Pipet a drop of stain onto the end of a slide, then pipet a small droplet of semen next to the stain. Many different sperm head abnormalities may be seen. Large heads (macrocephalic), small heads (microcephalic) and an absence of identifiable head are all seen in evaluations. Tapering sperm heads, pyriform heads (teardrop shape) and duplicate or double heads have been seen. Overall (gross) abnormalities in. Shaun. Age: 24. Hello Gentlemen, My name is Tami, an exclusive independent escort and courtisan from Budapest, Hungary Pyriform head: A frequent but little-studied morphological abnormality of sperm This study was conducted to investigate the frequency of sperm with a pyriform head in semen sam- ples, to determine the percentage of the occurrence of this abnormal sperm form, and to assess its possible correlation with other semen parameters. The study was designed as a retrospective data analysis in the setting of. Abnormal sperm morphology is classified as defects in the head, midpiece or tail of the sperm. (Pic. 2). Head defects include large, small, tapered, pyriform (pear-shaped) (Pic. 3), round, and amorphous heads (formless), heads with a small cap area (head area) and double heads, as well as any combination of.

Spermatozoa were classified into normal, having head defects (amorphous, small,large,pyriform,tapering), midpiece defects (including cytoplasmic droplets) and tail defects (Table 1). At least spermatozoa need to be examined in an attempt to reduce technical variation. Sperm morphology is determined using.
