As the According to NASCIMENTO & etiology, pathogenesis, symptoms, pathology and SANTOS (1997), unilateral cryptorchidism is treatment are similar for all locations, this review more frequent than bilateral. According to will not enter that description and will consider MIALOT (1988), the right testicle seems to be testicular ectopy and cryptorchidism as more frequently affected. He supposes that is synonymous. because embryologically, there is a longer migration (since they are originally located at the Incidence caudal region of the kidneys, and the right kidney According to HAFEZ (1995), is more cranial than the left one). Similarly, cryptorchidism incidence is greater in swine and CHRISTIANSEN (1986) suggests that the lack equines than in other domestic animals. However, of descent, in dogs, is found twice as often on according NASCIMENTO & SANTOS (1997), the right side as on the left (with a relationship of while the most affected species are the equine 2.3:1, for testis retained in the inguinal region, and canine, it may occur less frequently in other and 2:1 for abdominal retention).

NELSON & COUTO (1994) In most mammals, the testis originate describe a smaller prevalence in dogs and cats from the caudal portion of the kidneys, in the that is about 1% to 2%.

There is breed and descend to the scrotum during the fetal period predisposition in clinical practice as in the (SETCHELL, 1978, apud KAWAKAMI, et al. literature.

The descent of the testis is induced by that are most predisposed to cryptorchidism are the contraction of a gelatinous cord, the the Yorkshire terrier, Poodle, the smaller variants gubernaculum testis (Fig. 1), which extends from being most affected (toy > miniature > standard). the caudal pole of the testis to the genital tubercle The author also mentions that the Boxer and the (COX, 1986).

These authors the testis, extends through the inguinal canal and 62 The normal period for the descent of the testis to the scrotum is not strictly established in dogs or in cats. According to NASCIMENTO & SANTOS (1997), the testicles are usually present in the scrotum at birth in dogs. NELSON & COUTO (1994), NELIS (1995) and MICKELSEN & MEMON (1995) propose that in this species, the descent usually occurs at about 10 days of age. SORRIBAS (1995) mentions one month after birth, while ALLEN (1995) and MIALOT (1988) observed it within 10-12 weeks of age, and NIEMAND & SUTER (1992), at nine weeks. There is a breed variation (NELSON & COUTO, 1994; NASCIMENTO & SANTOS, 1997). In dogs, the testis are palpable in most of the cases from 4 to 5 weeks and usually within 6 to 8 weeks after birth (CHRISTIANSEN, 1986; MICKELSEN & MEMON, 1995; NASCIMENTO & SANTOS, 1997). However, Figure 1. Macroscopic appearance of testis (1), the diagnosis of cryptorchidism in dogs is not really gubernaculum (2) and gubernacular bulb (3) in certain before 6 months of age dog fetus (45 days). (CHRISTIANSEN, 1986). Pathogenesis The causes of cryptorchidism may be genetic, anatomical or endocrine. However, these down to the scrotum (MOORE & PERSAUD, causes are still controversial and may be 1994). The distal portion of the gubernaculum is intrinsically related. The genetic origin has been called the gubernacular bulb. It is sometimes incriminated countless times, since the condition thought that the expansion of the gubernacular has been frequently observed in inbred dogs bulb out of the abdominal cavity (Fig. 2) may (MIALOT, 1988). The most often accepted contribute to the traction that moves the testis hypothesis attributes it to an autosomal sex-linked caudally (COX, 1986). gene (ROMAGNOLI, 1991; MICKELSEN & MEMON, 1995), recessive in all examined Descent of the testis species (BURKE, 1986, MIALOT, 1988, Figure 2.

The MICKELSEN & MEMON, 1995), except in same author also reported parturition with the equine, in which it is due to a dominant autosomal male fetus in posterior presentation as gene (HAFEZ, 1995). Males and females carry compromising the blood supply to the testis and the gene and can transmit the pathology to their delay in the closing of the navel, causing offspring (NELSON & COUTO, 1994; retardation in the capacity for increasing the MICKELSEN & MEMON, 1995; abdominal pressure.

  • Clinical, Hormonal and Genetic Characteristics of Androgen Insensitivity Syndrome in 39 Chinese Patients Qingxu Liu, Xiaoqin Yin and Pin Li*
    Liu et al. Reproductive Biology and Endocrinology (2020) 18:34 https://doi.org/10.1186/s12958-020-00593-0 RESEARCH Open Access Clinical, hormonal and genetic characteristics of androgen insensitivity syndrome in 39 Chinese patients Qingxu Liu, Xiaoqin Yin and Pin Li* Abstract Background: Abnormal androgen receptor (AR) genes can cause androgen insensitivity syndrome (AIS), and AIS can be classified into complete androgen insensitivity syndrome (CAIS), partial androgen insensitivity syndrome (PAIS) and mild AIS. We investigated the characteristics of clinical manifestations, serum sex hormone levels and AR gene mutations of 39 AIS patients, which provided deeper insight into this disease. Methods: We prospectively evaluated 39 patients with 46, XY disorders of sex development (46, XY DSD) who were diagnosed with AIS at the Department of Endocrinology of Shanghai Children’s Hospital from 2014 to 2019. We analysed clinical data from the patients including hormone levels and AR gene sequences. Furthermore, we screened the AR gene sequences of the 39 AIS patients to identify probable mutations. Results: The 39 AIS patients came from 37 different families; 19 of the patients presented CAIS, and 20 of them presented PAIS. The CAIS patients exhibited a higher cryptorchidism rate than the PAIS (100 and 55%, P = 0.001). There were no significant difference between the CAIS and PAIS groups regarding the levels of inhibin B (INHB), sex hormone-binding globulin (SHBG), basal luteinizing hormone (LH), testosterone (T), or basal dihydrotestosterone (DHT), the T:DHT ratio, DHT levels after human chorionic gonadotropin (HCG) stimulation or T levels after HCG stimulation. However, the hormone levels of AMH (P = 0.010), peak LH (P = 0.033), basal FSH (P = 0.009) and peak FSH (P = 0.033) showed significant differences between the CAIS group and the PAIS group.

  • Multiple Congenital Genitourinary Anomalies in a Polled Goat
    Multiple Congenital Genitourinary Anomalies in a Polled Goat WILLIAM W. KING, DVM, PHD, DIPLOMATE, ACLAM,1,2* MELVIN E. YOUNG,1 AND M. EUGENE FOX, DVM3 A 1-day-old, Toggenburg/Nubian crossbred goat of polled parentage was referred for necropsy because of a large (diameter, 5 cm) bladder-like mass protruding from the perineal midline and difficult urination. Differential diagnoses included cutaneous cyst, ectopic urinary bladder, and urethral diverticulum/dilatation. Several genitourinary aberrations were noted. A second, smaller (diameter, 1 cm), more distal cystic structure was adjacent to an ambiguous prepuce. Testicles were discovered within a con- stricted, subcutaneous space near the inguinal canals. A rudimentary penis was located dorsal to the penile urethra with no appreciable urethral process. A tiny external urethral orifice was discerned only after liquid was injected into the lumen of the cystic structures, confirming their identity as urethral dilatations. The dilatations were separated by a constricting band of fibrous tissue. No other significant findings were detected. This case illustrates a combination of congenital anomalies including bilateral cryptorchidism with scrotal absence, segmental urethral hypoplasia, and urethral dilatation, most likely associated with the intersex condition seen in polled breeds. The continued production and use of small ruminants as animal models demands the prompt recognition of congenital anomalies. This case also exemplifies the precautions required when breeding goats with polled ancestry. The domestic goat (Capra hircus) has historically served and Nubian/Toggenburg sire.

However, its diagnosis is often delayed for reasons including patient unawareness or denial of abnormal findings in the testis. Moreover, it has been difficult to establish an optimal treatment strategy for postpubertal cryptorchidism, given the small number of patients. Unlike cryptorchidism in children, postpubertal cryptorchidism is associated with an increased probability of neoplasms, which has led orchiectomy to be the recommended treatment. However, routine orchiectomy should be avoided in some cases due to quality-of-life issues and the potential risk of perioperative mortality. Based on a literature review, this study proposes individualized treatment guidelines for postpubertal cryptorchidism.

  • Undescended Testicles, Retractile Testicles, and Testicular Torsion
    Undescended Testicles, Retractile Testicles, and Testicular Torsion This guideline, developed by Ashay Patel, D.O., in collaboration with the ANGELS team, on October 14, 2013. Last reviewed by Ashay Patel, D.O. November 4, 2016. Key Points Testicles should be palpable in the scrotum by 6 months of age. When testicles are not palpable, are unable to be brought to the scrotum, or do not remain in the scrotum by 6 months of age, a referral to a pediatric urologist is recommended for evaluation of an undescended testicle. Retractile testicles can be brought down to the scrotum and will remain there. If there is difficulty with bringing the testicles to the scrotum, a referral to a pediatric urologist is recommended. Testicular torsion outside of the perinatal period is a surgical emergency and emergent pediatric urology consultation is recommended. Perinatal testicular torsion presents with a painless firm testicle noted right after birth. A pediatric urology consultation is recommended.

  • Reproductive Chances of Men with Azoospermia Due to Spermatogenic Dysfunction
    Journal of Clinical Medicine Review Reproductive Chances of Men with Azoospermia Due to Spermatogenic Dysfunction Caroline Kang † , Nahid Punjani † and Peter N. Schlegel * Department of Urology, Weill Cornell Medical College, New York, NY 10021, USA; [email protected] (C.K.); [email protected] (N.P.) * Correspondence: [email protected] † Equal contribution. Abstract: Non-obstructive azoospermia (NOA), or lack of sperm in the ejaculate due to spermato- genic dysfunction, is the most severe form of infertility. Men with this form of infertility should be evaluated prior to treatment, as there are various underlying etiologies for NOA. While a significant proportion of NOA men have idiopathic spermatogenic dysfunction, known etiologies including ge- netic disorders, hormonal anomalies, structural abnormalities, chemotherapy or radiation treatment, infection and inflammation may substantively affect the prognosis for successful treatment. Despite the underlying etiology for NOA, most of these infertile men are candidates for surgical sperm retrieval and subsequent use in intracytoplasmic sperm injection (ICSI). In this review, we describe common etiologies of NOA and clinical outcomes following surgical sperm retrieval and ICSI.
