In this article, we report a case of pregnancy obtained in an infertile couple diagnosed with severe male factor infertility. The couple attended for fertility examination reporting a history of 10 years of infertility. The cause of infertility was obstructive azoospermia. The treatment consists of in vitro fertilization (IVF). The ovarian stimulation of female patient was done with antagonist protocol and after ovarian puncture was obtained nine oocytes. The urologist performed testicular sperm extraction (TESE). There were selected nine sperm cells by intra-cytoplasmic morphologically selected sperm injection (IMSI). For this purpose, we used an inverted microscope with high magnification equipped with ×60 air objectives with modulation contrast illumination. After intracytoplasmic sperm injection (ICSI) of sperm into the oocytes there were obtained six normal embryos from which three embryos were transferred into the uterus. A singleton pregnancy was achieved which was completed with birth of a healthy baby in time. This successful outcome shows that use of IMSI and ICSI procedures are really useful in selection of best spermatozoa obtained by TESE in treatment of obstructive azoospermia.

Background: Vasoepididymostomy (VE) is an important surgical treatment to achieve natural conception for patients with obstructive azoospermia (OA), and only unilateral VE can be performed under certain conditions, such as OA patients with congenital unilateral absence of the vas deferens (CUAVD) and some acquired OA. There is a lack of relevant reports assessing the clinical outcomes of unilateral VE in OA patients with different causes. This study is aimed to describe the clinical features and evaluate treatments and outcomes of unilateral single-armed VE in OA patients.

Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), is a long non-coding RNA localized in the cell nucleus, known for its multifunctional roles, including potential involvement in spermatogenesis. This study investigates the mechanism by which MALAT1 dysregulation contributes to the pathogenesis of idiopathic non-obstructive azoospermia (iNOA). We analyzed MALAT1 levels in two gene expression profiling datasets comprising patients with obstructive azoospermia (OA) who have normal spermatogenesis and 13 patients with iNOA.

Introduction: Infertility is a major public health issue, with male factors alone contributing to 20-30% of cases. Non-obstructive azoospermia (NOA) is the most severe form, and although techniques like microdissection testicular sperm extraction (mTESE) offer hope, it remains challenging due to its uncertain causes. This study investigates the correlation between testicular histopathology and clinical parameters to enhance sperm retrieval (SR) prediction.

Spermatogenesis is a sophisticated biological process by which spermatogonial stem cells (SSCs) undergo self-renewal and differentiation into spermatozoa. Molecular mechanisms underlying fate determinations of human SSCs by key genes and signaling pathways remain elusive. Here, we report for the first time that Yes1-associated transcriptional regulator (YAP1) is required for fate determinations of SSCs and male fertility by interacting with RAD21 and targeting NEDD4 in humans and mice.
