Postmortem Sperm Retrieval and Assisted Reproduction: Issues without Solutions?

Sperm retrieval techniques for assisted reproduction.

Different surgical methods such as PESA, MESA, TESA, TESE and micro-TESE have been developed to retrieve spermatozoa from either the epididymis or the testis according to the type of azoospermia, i.e., obstructive or non-obstructive. Laboratory techniques are used to remove contaminants, cellular debris, and red blood cells following collection of the epididymal fluid or testicular tissue. Surg...

Informed consent issues in assisted reproduction.

Given the enormous ethicolegal controversies surrounding the use of assisted reproductive technologies (ART) in the United States, the most important role for nurses may be helping couples and third party participants obtain fully informed consent. The high compensation fees for egg donors may place them at special risk of exploitation. New government and professional guidelines, broader repres...

ASSISTED REPRODUCTION Efficiency of hyaluronic acid (HA) sperm selection

Purpose Hyaluronic Acid (HA) has a role as “physiologic selector” for spermatozoa prior to intracytoplasmic sperm injection (ICSI). The objective of this study is to analyze the results achievable by the introduction of a routine HA-ICSI programme. Methods We retrospectively observed 293 couples treated with HA-ICSI versus 86 couples treated with conventional PVP-ICSI (historical control group)...

Ethical issues in assisted reproduction techniques for patients with disorders of sexual development

Impact of Intracytoplasmic Sperm Injection in Human Assisted Reproduction

The development of assisted reproductive technologies (ART) arises from the need to improve reproductive conditions, ensuring births in humans. Progress in this area of research has enabled the possibility of sperm selection with adequate morphological characteristics to ensure fertilization, embryo development, pregnancy and birth. However, further studies are required to increase reproductive...
