Assessment of the Relationship of Sperm Morphology with Seminal and Other Clinical Conditions of Semen Donors

Inter- And Intra-Breed Variation in Ejaculate Characteristics and in the Morphology, Dimensions and Shape of Spermatozoa of Boars Used for Artificial Insemination

“…A morphologically normal spermatozoon successfully reaches the ovum and initiates activation of the oocyte (Menkveld et al 2011). The morphological characteristics of spermatozoa may be influenced by the rate of sperm production in the testicular tissue and thus the number of sperm stored in the epididymis and released in the ejaculate (Hossain et al 1997;Silva et al 2012). The dimensions and shape of sperm have been shown to be correlated with ejaculate characteristics and male fertility (Rijsselaere et al 2004;Ramm et al 2014;Górski et al 2016).…”

Recent Advances in Andrology Research: Physiopathology and Clinical Application to Fertility and Infertility

“…Acrosomal defects and coiled tails are the most prevalent head and tail abnormalities, respectively (Figures 9 and 10). Sperm morphology is poorly related to race, body weight, smoking habits, and work environment [28]. …”

“…The following culture media are used for IVF and intrauterine insemination (IUI): Light photomicrograph of different types of morphological abnormalities observed in spermatozoa of study population. 1, normal; 2, double tail; 3 , abnormal acrosome (vacuolation); 4, double head, acrosome defect; 5 , amorphous head; 6, coiled tail, abnormal head (acrosome deficiency, elongated postacrosomal region); 7, bizarre head; 8, double head; 9, coiled tail; 10, normal, constricted head, abnormal acrosome; 1 1, pin head; 12, cytoplasmic droplet; 13, spear (constricted) head; 14, normal, abnormal acrosome; 15, giant head; 16, bent neck; 17, immature germ cell, white blood cell [28].…”
