Kallman syndrome and central non-obstructive azoospermia

Best Practice & Research Clinical Endocrinology & Metabolism, 2020
The understanding of male factors of infertility has grown exponentially in the past ten years. While clear guidelines for obstructive azoospermia have been developed, management of non-obstructive azoospermia has lagged. Specifically, management of Kallmann Syndrome and central non-obstructive azoospermia has been limited by a lack of understanding of

Microsurgical TESE and the distribution of spermatogenesis in non-obstructive azoospermia. [PDF]

Human Reproduction, 2000
We wished to map the distribution of spermatogenesis in different regions of the testis in 58 men with non-obstructive azoospermia, and to develop a rational microsurgical strategy for the testicular sperm extraction (TESE) procedure. One goal was to maximize the chances for retrieving spermatozoa from such men, to minimize tissue loss and pain, and to

Expert Opinion on Biological Therapy, 2017
Most male patients with non-obstructive azoospermia (NOA) have no therapeutic options outside of assisted reproductive techniques to conceive a biological child. If mature sperm cannot be obtained from the testes, these patients must rely on options of donor sperm or adoption.

Genetic mutations contributing to non-obstructive azoospermia

Best Practice & Research Clinical Endocrinology & Metabolism, 2020
Non-obstructive azoospermia is a distinct diagnosis within male infertility in which no sperm is found in the ejaculate as a result of spermatogenesis failure. Because of the increased prevalence of genetic abnormalities in men with non-obstructive azoospermia, male infertility guidelines recommend screening for karyotype abnormalities and Y chromosome

Patients with non-obstructive azoospermia (NOA), which accounts for up to 10-15% of all cases of male infertility, until recently could only become parents using donor sperm or through adoption. Modern technical capabilities of sperm extraction in combination with the use of assisted reproductive technologies, make it possible to effectively overcome ...
