{Transport of sperm through the cervix is assisted by all of the following except:
{During implantation of the blastocyst:
|type="()"}
|type="()"}
+ capacitation of the sperm
- usually implants in the posterior wall of the uterus
- the time of the female cycle
- release substances that cause local changes in the endometrial tissue
- properties of the cervical mucus
- attaches itself to the endometrium at its embryonic pole
- contractile activity of the uterus
- implantation can occur anywhere within the uterus or uterine tube
- pH
+ all the above are correct
|| Capacitation of the spermatozoa modifies the glycoprotein coat and seminal proteins, the spermatozoa are already motile before capacitation, and therefore capacitation does not assist transport of sperm through the cervix. All the other listed options aid cervical transport of spermat.  
|| All the above are correct!
 
{Implantation normally takes place in the:
|type="()"}
- cervical region
- two-thirds lateral uterine tube
- body of the uterus, most frequently on the anterior wall
+ body of the uterus, on the posterior wall
- peritoneal cavity
|| Body of the uterus, on the posterior wall.

BGDsmall.jpg

Here are a few simple Quiz questions that relate to Implantation from the lecture and practical.

  

1 Which of the following is essential for successful implanatation?

a decidual reaction
transport of the blastocyst to the uterine cavity at the right time
removal of the zona pellucida just before attachment of the blastocyst
release of Prostaglandin E2 by the endometrial stroma
all of the above are needed

2 Diagnostic tests for pregnancy are based mainly on:

levels of oestrogens
levels of progesterone
levels of thyroxin
secretion of human chorionic gonadotrophin (hCG)
secretion of human chorionic somatomammotropin (hCS)

3 During implantation of the blastocyst:

usually implants in the posterior wall of the uterus
release substances that cause local changes in the endometrial tissue
attaches itself to the endometrium at its embryonic pole
implantation can occur anywhere within the uterus or uterine tube
all the above are correct

4 Implantation normally takes place in the:

cervical region
two-thirds lateral uterine tube
body of the uterus, most frequently on the anterior wall
body of the uterus, on the posterior wall
peritoneal cavity
