Effects of lidocaine on equine ejaculated sperm and epididymal sperm post-castration.

Theriogenology 2019 Aug 16;134:83-89. Epub 2019 May 16.

Department of Population Health and Reproduction, School of Veterinary Medicine, University of California, 1 Garrod Drive, Davis, CA, 95616, USA. Electronic address:

In equids, it is common to inject lidocaine into the testicles at the time of routine castration to provide analgesia. The effects of lidocaine on equine sperm have not been evaluated in vitro or on epididymal sperm collected following castration. The aims of this study were to determine effects of clinically relevant doses of lidocaine on equine spermatozoa in vitro using freshly collected semen and to compare the characteristics of epididymal spermatozoa after routine castration with or without intra-testicular lidocaine administration.

Department of Pharmacology, Therapeutics and Toxicology, College of Medicine, University of Lagos, Lagos-Nigeria P.M.B 12003, Lagos-Nigeria. or

With the introduction of Highly Active Antiretroviral Therapy (HAART), there has been drastic decline in morbidity and mortality associated with HIV/AIDS. However, many patients experience adverse drug reactions perhaps due to the inherent toxic nature of HAART. The possible toxic effect of HAART (combination ARVs) on reproduction and sexual dysfunction in seropositive HIV patients remains a subject of intense research. Read More

Reprod Domest Anim 2017 Apr 3;52 Suppl 2:261-264. Epub 2016 Nov 3.

Department of Obstetrics, Gynaecology and Reproduction, Faculty of Veterinary Science, Chulalongkorn University, Bangkok, Thailand.

Sperm cryopreservation offers a long-term preservation of male genetic materials for future assisted reproductive technologies. However, dramatic changes in temperature during freezing and thawing injure sperm cells. While motility is essential for AI and membrane integrity is crucial for in vitro fertilization (IVF), sperm DNA integrity is a common index of fertilizing capability required for AI, IVF and intracytoplasmic sperm injection (ICSI).

Intratesticular and intraepididymal injections to sterilize male cats: From calcium chloride to zinc gluconate and beyond.

J Feline Med Surg 2015 Sep;17(9):772-6

Associate Professor of Companion Animal Industries, Department of Animal and Rangeland Sciences, Oregon State University, Corvallis, Oregon, USA

Aim And Rationale: The aim of intratesticular and intraepididymal injections is to provide an inexpensive non-surgical method for sterilizing tom cats. Intratesticular and intraepididymal injections have been studied for decades and warrant continued investigation. While both methods result in azoospermia, intratesticular injection of sclerosing agents induces orchitis, resulting in decreased spermatogenesis, whereas intraepididymal injection blocks sperm transport but does not alter spermatogenesis.

Reprod Domest Anim 2013 Dec 22;48(6):995-1000. Epub 2013 Jun 22.

Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Washington State University, Pullman, WA, USA; Center for Reproductive Biology, Washington State University, Pullman, WA, USA.

Azoospermia is a common finding in male alpacas which present for infertility. The challenge is to differentiate azoospermia of testicular origin from non-testicular origin. In several species, alkaline phosphatase (AP) concentrations in seminal plasma have been used as a diagnostic marker of contributions of the testis and epididymis to the ejaculate. Read More

Diagnostic epididymal and testicular sperm recovery and genetic aspects in azoospermic men.

Hum Reprod 1999 Jan;14(1):118-22

Centre for Reproductive Medicine, Sahlgrenska University Hospital, Göteborg University, Sweden.

Various procedures for sperm recovery in azoospermic men have been described, from open testicular biopsy to simple needle aspiration from the epididymis and the testis. Fifty-one obstructive and 86 non-obstructive azoospermic men were treated to compare the recovery of spermatozoa obtained by percutaneous aspiration from the epididymis (PESA) and aspiration/extraction from the testis (TESA, TESE) with histopathology. If TESA failed, the work up proceeded with TESE. Read More
