Q

how does the indifferent gonads decide it will develop into testes?

A

SRY on the Y chromosome codes for a protein called testes determining factor (TDF) which makes them develop into testes
also causes production of sertoli cells and leydig cells which cause release of testosterone and therefore male sex characteristics

16
Q

what is responsible for the gonads descending down from lumbar region to pelvic?

A

Gubunaculum

17
Q

what does the gabernaculum form in the female?

A

once the ovaries have reached the pelvis the gabernaculum forms the ovarian ligament

18
Q

why are females less likely to have indirect inguinal hernias?

A

the ovaries don’t descend through the inguinal canal and therefore the canal is smaller in females therefore less prone

19
Q

when are the testes fully descended?

A

8 months

20
Q

what is cryptochordism?

A

absence of testes in scrotum

21
Q

what are the complications of undescended testes?

A

infertillity
malignant transformation (germ cell tumours)
testicular torsion

22
Q

what is the management for cryptochordism?

A

orchiopexy

23
Q

at what weeks is there greatest risk of complications from teratogens?

A

1st trimester weeks 3-11

24
Q

what complications occur due to exposure from teratogens in the 3rd trimester?

A

growth and/or functional deficits

25
Q

where does the lower part of the vagina and the vulva develop from?

A

urogenital sinus

26
Q

what are the clinical features of foetal alcohol syndrome?

A 
low nasal bridge 
underdeveloped lower jaw 
thin upper lip
smooth and large philtrum 
small head 
small eye opening 
flat mid face
