Internal Genitalia
Male
- Ductus Deferens - unilateral or bilateral absence congenital unilateral absence of the vas deferens (CUAVD), Congenital bilateral absence of the vas deferens (CBAVD)
failure of mesonephric duct to differentiate frequent cause of obstructive azoospermia 75% of men with bilateral absence have at least one detectable common mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene
Female
Uterine Duplication, Unicornate Uterus, Septate Uterus.
This cartoon shows the new 2013 ESHRE-ESGE classification system [1] based on uterine anatomy, embryological origin is the secondary basic characteristic, and both cervical and vaginal anomalies are classified in independent co-existent sub-classes. For more detail see Additional Information.
- Cervical - cervical agenesis, cervical duplication
- Vagina Absence - Failure of sinovaginal bulb development, 1 in 4,000 to 5,000 female births.
Other Abnormalities
Use the links to find out more about these topics.
- Congenital Adrenal Hyperplasia - impairment of cortisol production by the adrenal cortex, is one of the most common causes of intersex genitalia at birth.
- Androgen Insensitivity Syndrome - genetically male (XY) unable to respond to male sex hormones (androgens), they may have mostly female sex characteristics or signs of both male and female sexual development. Also a partial androgen insensitivity syndrome (PAIS) associated with impaired male genital development that can be transmitted through mutations in the androgen receptor.
- Cryptorchidism - covered in detail above.
- Undescended Ovaries - reasonably rare gonad abnormality, often detected following clinical assessment of fertility problems and may also be associated with other uterine malformations (unicornuate uterus).
- Hydrocele - covered above, most commonly male (but can also be female) fluid-filled cavity.

Disorders of Sex Development
The previous human sex development terminology (true hermaphrodites, male pseudohermaphrodites and female pseudohermaphrodites) are considered outdated and stigmatising and have been replaced with the general term Disorders of Sex Development (DSD) established by the Consensus statement on management of intersex disorders.[2] See also the Medical Journal of Australia 2009 editorial article.[3]
Previous Terminology | New Proposed Terminology |
Intersex | DSD |
Male pseudohermaphrodite, undervirilization of an XY male, and undermasculinization of an XY male | 46,XY DSD |
Female pseudohermaphrodite, overvirilization of an XX female, and masculinization of an XX female | 46,XX DSD |
True hermaphrodite | Ovotesticular DSD |
XX male or XX sex reversal | 46,XX testicular DSD |
XY sex reversal | 46,XY complete gonadal dysgenesis |

Hypospadia
Hypospadia Classification | Meatus Opening |
Anterior | on inferior surface of glans penis |
Coronal | in balanopenile furrow |
Distal | on distal third of shaft |
Penoscrotal | at base of shaft in front of scrotum |
Scrotal | on scrotum or between the genital swellings |
Perineal | behind scrotum or genital swellings |
- Epispadias - Uncommon abnormality associated with the penis, 1 in 30,000 infant males, external urethral opening on the dorsal surface of penis.
- Cryptorchidism in common eutherian mammals.[4]- Species comparison of descent timeline
- Mayer-Rokitansky syndrome (MRK anomaly, Rokitansky-Küster-Hauser syndrome, RKH syndrome, RKH) congenital absence of the vagina, dyspareunia, vaginal agenesis.

- Uterine Duplication (uterus didelphys, double uterus, uterus didelphis) A rare uterine developmental abnormality where the paramesonephric ducts (Mullerian ducts) completely fail to fuse generating two separate uterus parts each connected to the cervix and having an ovary each. Failure of fusion of lower paramesonephric ducts, with either double or single vagina.
- Unicornate Uterus - failure of the paramesonephric ducts to fuse. A single paramesomnephric duct has fused with the vaginal plate and now opens into the vagina, while the other forms a diverticulum.
- Septate Uterus
Polycystic Ovary Syndrome
(PCOS) or Stein–Leventhal syndrome (1930s researchers) a metabolic syndrome with many other symptoms, ovarian cysts arise through incomplete follicular development or failure of ovulation. For review see [5]
Environmental Abnormalities
- Diethylstilbestrol (DES or diethylstilbetrol) - is a drug that was prescribed to women from 1938-1971 to prevent miscarriage in high-risk pregnancies.
- The drug acted as a potent estrogen (mimics natural hormone) and therefore could also act as a potential endocrine disruptor.
- This led to a number of developing fetal reproductive tract and other abnormalities.
- In the female fetus, it increased risk of abnormal reproductive tract and also carcinogenic (cancer forming).
- In the male fetus, it increased the occurance of abnormal genitalia.
- The drug was banned by FDA (USA) in 1979 as a teratogen, it had previously also been used as livestock growth promoter and could have potentially entered the human food chain.
