Reproduction is a biological process by which a new organism is produced from its parents. Reproduction is vital for the survival and continuity of a species. Infertility is a major issue in the world. Apart from its biological consequences, it is also a social stigma and a major cause of mental health issues in many parts of the world.
A recent clinical trial has evaluated the success rates of two different procedures used for the retrieval of sperm in infertile men who wish to become biological fathers.
Infertility is a growing concern for many couples around the world, and in men, nonobstructive azoospermia is a common cause of infertility. Nonobstructive azoospermia is a condition in which the testes produce little or no sperm, which makes it difficult for men to father a child. It is the most severe form of male infertility. In vitro fertilization (IVF) is a common treatment option for infertility. However, there are different methods for obtaining sperm from the male, including microdissection testicular sperm extraction (mTESE) and multiple needle-pass percutaneous testicular sperm aspiration (TESA).
mTESE is a surgical procedure in which a microscope is used to identify and extract a small amount of sperm-containing tissue from the testes. The sperm are then retrieved from this tissue. TESA, on the other hand, involves using a needle to extract sperm directly from the testes without the need for testicular surgery. However, clinical data on the effectiveness of either technique is deficient.
In a bid to rectify this, a clinical trial was conducted recently to measure the success rates of mTESE and TESA for obtaining sperm from the testis of infertile men who had a complete absence of sperm in their semen.
