Hematospermia (also known as haematospermia, hemospermia, or haemospermia) is the presence of blood in the ejaculate. It is most often a benign symptom. [1] Among men age 40 or older, hematospermia is a slight predictor of cancer, typically prostate cancer. [2] No specific cause is found in up to 70% of cases.
Semen normally has a whitish-gray colour. It tends to get a yellowish tint as a man ages. Semen colour is also influenced by the food we eat: foods that are high in sulfur, such as garlic, may result in a man producing yellow semen. [19] Presence of blood in semen (hematospermia) leads to a brownish or red coloured ejaculate. Hematospermia is a ...
Sertoli cell-only syndrome is usually initially assessed by conducting two separate semen analyses. Sertoli cell-only disease is frequently characterized by azoospermia which is the complete absence of sperm in semen. A tiny fraction of patients may still have measurable sperm levels. [1]
Furthermore, cleavage-stage biopsy, as in the case of PB biopsy, yields a very limited amount of tissue for diagnosis, necessitating the development of single-cell PCR and FISH techniques. Although theoretically PB biopsy and blastocyst biopsy are less harmful than cleavage-stage biopsy, this is still the prevalent method.
Symptoms can include vague back or lower abdominal pain; pain of the penis, scrotum or peritoneum; painful ejaculation; blood in the semen on ejaculation; irritative and obstructive voiding symptoms; and impotence. [16] Infection may be due to sexually transmitted infections, as a complication of a procedure such as prostate biopsy. [9]
[4] [5] After almost 40 years of being overlooked, Boreau revived the procedure in the 1950s. [4] Then, vasography was somewhat overused for various fertility disorders and other diseases such as tuberculosis , prostate cancer , hemospermia , and compressive fibrolipomatosis , without considering the possible risks and complications from the ...
The blood-testis barrier is likely to contribute to the survival of sperm. However, it is believed in the field of testicular immunology that the blood-testis barrier cannot account for all immune suppression in the testis, due to (1) its incompleteness at a region called the rete testis [ 29 ] and (2) the presence of immunogenic molecules ...
In this study, azoospermic men underwent simultaneous testis biopsies and site-matched FNA, and FNA was found to be more sensitive in detecting sperm, as several men had sperm found by FNA but not on biopsy. [17] Additionally, in one-third of patients, localized areas of sperm were detected by FNA in areas distant from biopsy sites without sperm.
