Sperm DNA fragmentation and apoptosis in the sperm of men with oligozoospermia are closely related to anti-ODF2 autoantibodies.

Pathology, Research and Practice, 2023
BACKGROUND Around 15% of couples of childbearing age suffer from infertility; in 50% of these cases, the male factor is present. In this study, we investigated the association between anti-ODF2 autoantibody existence and the DNA fragmentation and ...

TESTICULAR SPERM ASPIRATION (TESA) OR MICRODISSECTION TESTICULAR SPERM EXTRACTION (MICRO-TESE): WHICH APPROACH IS BETTER IN MEN WITH CRYPTOZOOSPERMIA AND SEVERE OLIGOZOOSPERMIA?

Urology, 2021
OBJECTIVES To evaluate and compare sperm retrieval outcomes by testicular sperm aspiration (TESA) and micro-dissection testicular sperm extraction (micro-TESE) in non-azoospermic men.

Single sperm vitrification with permeable cryoprotectant-free medium is more effective in patients with severe oligozoospermia and azoospermia.

Cryobiology, 2021
Testicular sperm extraction (TESE) is an invasive surgery for achieving the spermatozoa in cases with azoospermia. In these patients, the number of retrieved spermatozoa is limited and the optimal cryo-storage is very critical for their fertility ...

Recombinant FSH in the treatment of oligozoospermia

Expert Opinion on Biological Therapy, 2009
FSH plays a crucial role in human reproduction. Treatment with gonadotrophins has been shown to be effective in males affected by hypogonadotrophic hypogonadism. The success of this treatment has brought about the utilization of the same therapy in infertile oligozoospermic subjects, aimed at obtaining increased sperm count.

Tamoxifen Treatment in Oligozoospermia

European Urology, 1981
This study of the effects of long-term tamoxifen administration on semen analysis of oligospermic males confirms the potential therapeutic efficacy in normogonadotrophic oligospermia. 38 out of the 56 patients responded well to long-term treatment with 30 mg tamoxifen daily.

Ursonic acid attenuates spermatogenesis in oligozoospermia mice through inhibiting ferroptosis

Bioorganic Chemistry
Ursonic acid (UNA) is a natural pentacyclic triterpene found in some medicinal plants and foods. The reproductive protective effect of UNA was evaluated in a mouse model of oligozoospermia induced by busulfan (BUS) at 30 mg/kg b.w..

An M1AP homozygous splice‐site mutation associated with severe oligozoospermia in a consanguineous family

Clinical Genetics, 2020
Severe oligozoospermia (SO) is an important cause of male infertility. Its etiology and pathogenesis are associated with genetic abnormalities; however, the genetic causes of the majority of idiopathic human SO remain unclear.

L-Dopa and Oligozoospermia

Andrologia, 2009
A clinical investigation of L-Dopa on idiopathic oligozoospermia is carried out. Thirty nine male oligozoospermic patients with primary sterility were divided in two groups. The first group of 25 patients was treated with 500 mg a day during two months. The second group of 14 patients received 750 mg a day for the same time.
