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.
In both men and women, ASA production are directed against surface antigens on sperm, which can interfere with sperm motility and transport through the female reproductive tract, inhibiting capacitation and acrosome reaction, impaired fertilization, influence on the implantation process, and impaired growth and development of the embryo.
If more than 10% of the sperm are bound to anti-sperm antibodies (ASA), then infertility is suspected. The blood-testis barrier separates the immune system and the developing spermatozoa. The tight junction between the Sertoli cells form the blood-testis barrier but it is usually breached by physiological leakage.
For women ages 40–44, the birth rate increased 4 percent between 2021 and 2022 (and has been continually inching up since 1985), while the birth rate for women ages 45 and over increased 12 percent.
Sperm granulomas may also have a yellow, white, or cream colored center when cut open. While some sperm granulomas can be painful, most of them are painless and asymptomatic. [2] Sperm granulomas can appear as a result of surgery (such as a vasectomy), trauma, or an infection (such as sexually transmitted diseases). [3]
Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility.This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and cryopreservation of gametes and embryos, and the use of fertility medication.
Among males oligospermia is defined as a paucity of viable spermatozoa in the semen, whereas azoospermia refers to the complete absence of viable spermatozoa in the semen. [4] Males may also experience issues in sperm motility and morphology, which means the sperm are less likely to make it to the egg or to be able to fertilize the egg. [6]
