This would result in a quick (within 3-4 years) end of the world scenario (for human civilization, that is).

Here is how the timeline of changes which would occur.
15 seconds of male population death: Tens of millions of cars, buses, lorries, trucks etc will crash or get off the road, causing a very high death toll of women, baby girls and (possibly) pet animals.
1 minute after the catastrophe: This global disaster (traffic accidents), along with immediate death of all men in homes and workplaces would cause a global hysteric reaction all over the world. Considering that landlines and mobile phone lines would still be operational, there would be a massive overload of communication channels as women all over the world call their loved ones or for emergency help services.
10 minutes after the catastrophe: There is global panic, hysteria and confusion as the extent of loss is realized. A lot of suicides and heart failure deaths are expected as lovers, newly wed brides and young mothers learn their loved ones are dead.
30 minutes after the catastrophe: A lot of women die in hospitals due to panic, failure of emergency services and ensuing confusion.
1 day after the catastrophe: With traffic jams all over the world, a lot of women would die due to hunger. Also note that circus animals (including lions and tigers) would have escaped by now. Zoo animals are getting frustrated and panicking due to hunger, noise and confusion. Mega mammals such as elephants, hippos and rhinos would be testing the strength of their enclosures by now.
2 days after the catastrophe: Many power stations and communication channels fail all over the world leaving the world in darkness (at night) and cold (for regions where it is winter). In mega cities, most bakeries and stores have been raided by now by hungry women and most supplies have been consumed, leaving little behind. Wild animals such as elephants, hippos, rhinos, tigers and lions would have broken out of their fences as the electric fencing has failed. The carnivores find a feast in the form of billions of dead men on the streets all over the world, while the herbivores panic and try to flee out of the cities in search of vegetation.
5-10 days after the catastrophe: Exhaustion of food supplies in cities starts to tell on the women and with communication channels failure, there would be large scale riots and panic as the survivors try to search for more resources and move out of the cities. By now the billions of corpses are starting to decay, creating unimaginable stench and fear. Also by this time, security measures in power plants would begin to fail. This would not result in Chernobyl-like disasters, but Fukushima-like disasters. Basically, the water in coolant systems would heat up, and with no fresh water supply, the water would turn into steam which would create massive (but non nuclear) explosions. The explosions would not be lethal, but the fallout would have severe negative implications. (See Aftermath: Population Zero for detail).
10-15 days after catastrophe: By now the stench in the cities would be unbearable. Any woman unlucky enough to be left over in the cities would be almost certainly dead due to lack of food, failure of services (including electricity and gas) and the growing unhygienic conditions. Most of the urban survivors would have reached villages and rural settlements by now and a stable social system would finally start to emerge by now.
1 month after catastrophe: The fallout from nuclear reactors would be spread through rains and winds, affecting hundreds of millions of survivors. Efforts would begin to be made for salvaging stored sperms in sperm banks. It is unknown if those stored sperms would still be viable, considering the lack of maintenance and electric failure (most probably not). The currency system which had been working by now, would start to fracture and fall by now. The world would start returning to barter system now. Also, gold which was so prized before the catastrophe, would begin to lose its charm now, as there are no men to admire the beauty.
6 months after catastrophe: The only good effect of the human male extinction would begin to show now. Wildlife in all areas of the world would start to recover and proliferate. Also, there would only be around 30% or so survivors within the female population. Tech advancement and social structures would have crumbled. Also, the removal of male population might have some long term implications on the sex drives of women. Readers can imagine the consequences themselves. I would not go in detail of such sensitive issue here.
2 years after catastrophe: If there was any success in salvaging the sperms (very low probability), the world might have another generation of women. The tech level of the world is nearly that of 100 years go, except that some remnants of technological age (guns, clothing, shoes etc) linger on until supplies exhaust.
10 years after catastrophe: Wild carnivores would start becoming a threat now. Tigers, leopards, jaguars, bears and wolf packs would now be expected to be encountered once in a while.
15 years after catastrophe: Old times (with men) are completely forgotten by now. Wild animals are greatly feared. The only human settlements are in rural areas. There is no technology of old times left anymore. Parties of women occasionally visit former cities once in a while in search of salvaging useful consumables.
And that would be the state of affairs until most of the first generation dies in 30 years or so, with no hopes of repopulating Earth again.
