FSH stimulates sex cell production; LH stimulates gonadal hormone production.
2.
Negative feedback of gonadal hormones inhibits gonadotropin release.
3.
Gonadal hormones from the testes, such as testosterone and antimullerian hormone are required to cause development of a phenotypic male.
4.
These differences may be due to the presence of gonadal hormones which have been demonstrated to influence cell structure in the hippocampus.
5.
They influence gonadal hormone secretion, for example, follicle maturation in the ovaries in females and testosterone and sperm production in males.
6.
They concluded : " The findings suggest that, throughout life, gonadal hormones remain essential for maintaining aspects of sex-specific differences in the human brain ."
7.
They also found that males outperformed females in the Iowa Card Task, but there was a negative correlation between elevated testosterone levels and performance in the card task which indicates gonadal hormones influence decision-making.
8.
Women who had their uterus and ovaries removed for medical reasons and lost their gonadal hormones showed a decrease in short-term verbal ( hippocampus ) and working memories ( pre-frontal cortex ), yet with estrogen therapy the memory loss was prevented.
9.
The Phoenix et al . study sought to discover whether gonadal hormones given during the prenatal period had organizing effects on guinea pigs reproductive behavior It was found that when female controls, gonadectomized ( removal of gonads ) females, hermaphrodites, and castrated males were injected prenatally with testosterone proprionate, the mean number of mounts increased.
