1) Ectopic ureter draining into the genital system is a rare entity and results from a more cranial origin of the ureteral bud from the mesonephric duct with resultant ureteral stump opening in the mesonephric duct derivatives (seminal vesicles, ejaculatory ducts, or vas deferens).
However, the ovotestes of all FPSHs retained a small testicular portion with well developed ejaculatory ducts containing sperm.
8 long setae; gonostylus with a pair of spiniform proximal setae located at about the same level, one median spiniform seta inserted near the proximal setae and distant from the two apical spiniform setae, without subapical fine seta; paramere narrow at middle, with the apical portion broader apex rounded pointed and with a triangular small projection in the ventral edge near the apex, basally with a dorsal spinose rounded lobe; lateral lobe thin; ejaculatory ducts with lanceolate apex.
The anomalies associated with CUAVD include seminal vesicles and ejaculatory ducts anomalies, cryptorchidism, malrotation of the solitary kidney, multi-cystic kidney, ectopic kidney, and horseshoe kidney and they are often asymptomatic so that they are diagnosed incidentally during orchidopexy or surgical exploration for inguinal hernias or even during evaluation for infertility in adults.
Common Genetic Abnormalities found in Different Categories of Azoospermia Cystic fibrosis Karyotype Y-microdeletion Absence or obstruction 25-80% of the vas deferens, epididymis or ejaculatory ducts Testicular failure 14% 1-30%
Shoskes says this new approach eventually may serve as an alternative to medications and surgery for BPH, but in a limited number of patients: those with a moderately large prostate who don't have a large median lobe (a cone-shaped portion of the prostate situated between the ejaculatory ducts and the urethra).
Why can't the fluid secreted by the prostate during ejaculation simply be added to the sperm through ejaculatory ducts as it passes by the prostate, rather than through it, like vehicles entering the freeway from an on-ramp?
Adenomatoid tumour usually involve the genitourinary system in both males and females, with fallopian tubes, ovaries and uterus being common areas for females and epididymis, testes, spermatic cord, ejaculatory ducts in males.
The following factors should be considered in differential diagnoses: cystadenomas and papillary adenomas of the seminal vesicles, Msellerian duct cysts, diverticula of the ejaculatory ducts or ampulla of the vas, prostatic cysts, adenocarcinoma or sarcoma of the seminal vesicles, and secondary malignant tumors of the vesicles caused by adjacent organs and lymphomas.
Obstruction of the ejaculatory ducts may be suggested by the sonographic findings of dilated seminal vesicles or ejaculatory ducts.
This is seen in hypogonadal men after a short abstinence time and where ejaculation or emission of fluid is impaired, such as in neuromuscular diseases, after surgery, in cases of drug use, and in obstruction in the ejaculatory ducts, or with inflammation in the vesicles or prostate that may hinder emission.
Besides the epididymis, adenomatoid tumor can be located in the spermatic cord, prostrate, ejaculatory ducts and scrotal capes and in females it can be located in uterus, fallopian tubes and ovaries (6).
