Foi realizado um estudo morfométrico de testículos escrotais e retidos de 10 eqüinos criptórquios unilaterais, sendo cinco abdominais e cinco inguinais. As características avaliadas foram espessura da albugínea testicular, área dos túbulos seminíferos e número de células de Leydig. A espessura da albugínea testicular mostrou-se reduzida (P< 0,05) nas gônadas criptórquias abdominais quando comparadas às escrotais contralaterais. Também foram observadas diferenças (P< 0,01) nas áreas dos túbulos seminíferos dos testículos abdominais e inguinais, que se apresentaram diminuídas quando comparadas às dos escrotais contralaterais. A diminuição foi de, aproximadamente, 45% nos testículos abdominais e de 31% nos inguinais. Não foram verificadas diferenças (P> 0,05) na contagem de células de Leydig das gônadas criptórquias comparadas às escrotais contralaterais. Nos eqüinos, o criptorquismo afetou com maior intensidade a área dos túbulos seminíferos dos testículos abdominais e inguinais e a espessura da albugínea daqueles retidos no abdome.Morphometrical study was performed in scrotal and retained testes of 10 unilateral cryptorchid horses, five abdominal and five inguinal. Thickness of the testicular albuginea, area of seminiferous tubules and number of Leydig cells were evaluated. Abdominal retained testes showed a reduction in the thickness of testicular albuginea in comparison to the contralateral scrotal testes (P 0.05) were observed in the Leydig cell count of the retained testes in comparison to the contralateral scrotal testes, justifying that testosterone production in the cryptorchid horses was similar to the normal stallion. The equine cryptorchidism affected with major intensity the area of seminiferous tubules of abdominal and inguinal testes and the thickness of testicular albuginea of the abdominal testes.

Cats are gradually occupying a more important position as pets and this preference is a result of how easy cat maintenance in an urban environment is, even though they are very prolific and need surgical sterilization. This paper aims at evaluating obtained data within 15 years of research in a university service program that offers free cats sterilization surgery. We carried out a statistical analysis of data shown in the records of animals treated by the program. Surgical sterilization was performed on 647 animals (409 females - 63% and 238 males - 37%). Unilateral cryptorchidism was observed in 9 (3.8%) male cats. Forty (10%) female cats were pregnant at the time of the surgery and the treatment with contraceptives was observed in 67 (16.4%) female cats. One death occurred during anesthesia recovery and 2 cats were euthanized because of wound infection, totalizing an amount of 0.5% of severe complications. From 1996 to 2004, 212 female cats were spayed (122 adults and 90 prepubertal) and during that time two different approaches for ovariohysterectomy were compared: flank laparotomy and ventral midline celiotomy. The flank laparotomy approach was used in only 46 female cats (21.7%) due to some disadvantages observed - the need of an incision on each flank in prepubertal or nulliparous animals and the difficulty or impossibility of total uterus removal. In the same period, 105 male cats underwent orchiectomy via an open technique in which the spermatic cord was linked with nylon thread. From 2005 to 2010, 197 females (106 adults and 91 prepubertal) were spayed. The minilaparotomy technique was used to perform ovariohysterectomy on 139 female cats (70.6%). In this procedure, ovaries and uterus were exteriorized in a blind fashion with a hook through a small midline incision. The traditional midline ovariohysterectomy, which incision length permits direct visualization of the ovaries and uterus, had to be performed in 58 (29.4%) female cats due to advanced pregnancy, full urinary bladder during surgery or obesity. Over the past 6 years, 133 male cats (48 adults and 85 prepubertal) were castrated by means of an open technique in which the spermatic cord was tied to itself. The demand for surgeries during the project demonstrated that people are becoming aware concerning the importance of sterilization when facing cat overpopulation and abandonment.

A 36 year-old man after tests for assessing male infertility was diagnosed with primary infertility, bilateral cryptorchidism, nonobstructive azoospermia and discontinuous splenogonadal fusion. Carcinoma in situ was found in his left testicle, which was intraabdominal and associated with splenogonadal fusion. To our knowledge, this is the fourth case of splenogonadal fusion associated with testicular cancer reported. One should always bear in mind the possibility of this association for the left cryptorchid testicle. [ABSTRACT FROM AUTHOR]

An uncommon case of malignant testicular interstitial cell tumor (TICT) with multifocal metastases in a dog is described. The dog had the left testis enlarged, with inguinal cryptorchidism and multifocal cutaneous nodules that were surgically removed and submitted for histopathological examination. The diagnosis was of malignant TICT with cutaneous metastasis. A month later the dog was submitted to euthanasia and necropsy. Disseminated cutaneous metastases and metastases to the internal iliac lymph nodes and abdominal skeletal muscles were observed. Neoplastic cells were positive for vimentin by immunohistochemistry.
