Well, seeing as we don't even know whether or not aliens are real, I don't believe anybody can answer this question. But if you really want an answer, I will give you an answer. Based on common theory among a group of scientists called ancient astronaut theorists, the extraterrestrials that most abduction victims claim to have seen, commonly called Greys, have evolved so much from humans that they no longer have sex organs, and either reproduce by some unexplainable means or are genetically engineered by another race, perhaps one that does reproduce naturally. As for people from other countries, yes, they do reproduce.
Your question reminds me of the character Quagmire from the Family Guy. Why? Because only him or the character "Tig" from Sons of Anarchy would be interested in seeing a character like "E.T." perform the mechanics of bi-sexual reproduction. They could be severly disappointed to discover that they reproduce A-sexually or perhaps even TRI-sexually???
It depends on what you mean by "aliens." If your talking about the type of aliens that we see in fiction today there has never been any conclusive proof that such exists. Then again if what you mean by "aliens" is any form intelligent life that originated, is located or occurs outside Earth's atmosphere then yes he has reproduced. The Bible says that "God is a Spirit" and though invisible to human eyes he is credited to the creation of the entire universe. Speaking of God's first reproduction, the man who came to be known as Jesus, the Bible says, "He is the image of the invisible God, the firstborn of all creation; because by means of him all other things were created in the heavens and upon the earth." By creating an inferior counterpart, image, or copy of himself, God had indeed reproduced and apparently he granted his son Jesus the power and authority to assist in bringing all other things into existence.
Who knows if reproduction is a quirk of our evolutionary corner of the universe? It certainly would seem to me from what we know of the periodic table and the tendencies some elements have to form long chains that this copy and paste nature leads necessarily to reproduction of the kind we're used to.
It seems reasonable that some kind of self-repair technique would be utilized, and this is accomplished--at least by earth life--by reproducing existing cells into fresh ones. I would kind of generalize from there over to the entire life form.
It will be exciting to study newly found life that got started independently of our lineage. Here's hoping the oceans of Europa contain some!
Aliens or extra terrestrials as society calls them are real in a sense that they are real entities, but they fool humanity with the illusion of evolution by saying they are evolved beings from other worlds. The fact is that they have been around for a very long time in our existence as fallen angels and demons. They are not extra terrestrials, but they are inter dimensional. They reproduced as the Genesis story recalls in chapter 6. But they were punished by God for doing so as it was forbidden .

Yes I believe that they have a way to reproduce, maybe not like us since they are a totality different species. Some species here on earth don't touch. The females lays the eggs the males ejacalates on the eggs. We are very lucky to find love and reproduce the way that we do.
