There are some verses of the Qur'an which are written as if the reader is male, which makes me wonder:
Question: Was the Qur'an intended to be read by men?
Maybe I'm reading too much into this, but for example, men are referred to using "you":
Your wives are a place of sowing of seed for you, so come to your place of cultivation however you wish and put forth [righteousness] for yourselves. And fear Allah and know that you will meet Him. And give good tidings to the believers. -- Qur'an 2:223
And you will never be able to be equal [in feeling] between wives, even if you should strive [to do so]. So do not incline completely [toward one] and leave another hanging. And if you amend [your affairs] and fear Allah - then indeed, Allah is ever Forgiving and Merciful. -- Qur'an 4:129
O you who have believed, indeed, among your wives and your children are enemies to you, so beware of them. But if you pardon and overlook and forgive - then indeed, Allah is Forgiving and Merciful. -- Qur'an 64:14
But what about women believers (who ordinarily don't have wives)?
Women are instead referred to as if they're not the reader:
... So righteous women are devoutly obedient, guarding in [the husband's] absence what Allah would have them guard. ... -- Qur'an 4:34
And tell the believing women to reduce [some] of their vision ... -- Qur'an 24:31
Prohibited to you [for marriage] are your mothers, your daughters, ... -- Qur'an 4:23
