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

K Chatdarong

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.

Effects of vasectomy on seminal plasma alkaline phosphatase in male alpacas (Vicugña pacos).

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

In utero and lactational exposure of the male Holtzman rat to 2,3,7,8-tetrachlorodibenzo-p-dioxin: decreased epididymal and ejaculated sperm numbers without alterations in sperm transit rate.

Toxicol Appl Pharmacol 1996 Sep;140(1):146-53

School of Pharmacy, University of Wisconsin, Madison 53706, USA.

Decreased daily sperm production (DSP) and cauda epididymal sperm number (CESN) are some of the most sensitive effects of in utero and lactational 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure. The reduction in CESN cannot be fully accounted for by decreased spermatogenesis. To explain the decrease in CESN it was hypothesized that TCDD exposure increases the rate of sperm transit through the excurrent duct system, thereby decreasing the number of sperm in the system at any given time.

Surgical exploration of the horse that has presumably had a normal castration or a previously successful cryptorchid surgery remains a distinct challenge. No hard and fast rules dictate a proper course of action for each case. If a horse was anesthetized for routine castration, discovered to have only one scrotal testis, had a brief exploratory on the nondescended side and was recovered, trauma to the inguinal region would probably be sufficiently minimal that an inguinal approach could be used at subsequent exploratory surgery.

To prevent urogenital infections occurring after urethrocystoscopy, we have studied the prevalence of these diseases without the use of antibiotic agents subsequent to urethrocystoscopy to determine the relative importance of aseptic procedures and whether administration of antibiotics is really required for this purpose. Patients enrolled in the present study included those undergoing urethrocystoscopy at four hospitals, totaling 146 patients (93 male and 53 female patients). All of these patients were apparently free of urogenital infections prior to urethrocystoscopy, with less than 5 leucocytes per field in urinary sediment, and a bacteria count of less than 10(4) cells/ml.
