According to Brigham Young, the second prophet and president of the LDS church:
"The birth of the Savior was as natural as the births of our children; it was the result of natural action. He partook of flesh and blood--was begotten of his Father, as we were of our fathers."
(Journal of Discourses, vol. 8, p. 115).
"I have given you a few leading items upon this subject, but a great deal more remains to be told. Now, remember from this time forth, and for ever, that Jesus Christ was not begotten by the Holy Ghost."
(Journal of Discourses, vol. 1, p. 51).
According to Orson Pratt the original member of the Quorum of Twelve Apostles of the Church of the Latter Day Saints:
The fleshly body of Jesus required a Mother as well as a Father. Therefore, the Father and Mother of Jesus, according to the flesh, must have been associated together in the capacity of Husband and Wife; hence the Virgin Mary must have been, for the time being, the lawful wife of God the Father: we use the term lawful Wife, because it would be blasphemous in the highest degree to say that He overshadowed her or begat the Savior unlawfully.
(Orson Pratt, The Seer, page 158)
According to Luke 1:26-28:
31 You will conceive and give birth to a son, and you are to call him Jesus.
32 He will be great and will be called the Son of the Most High. The Lord God will give him the throne of his father David,
33 and he will reign over Jacob’s descendants forever; his kingdom will never end.”
34 “How will this be,” Mary asked the angel, “since I am a virgin?”
35 The angel answered, “The Holy Spirit will come on you, and the power of the Most High will overshadow you. So the holy one to be born will be called[a] the Son of God.
36 Even Elizabeth your relative is going to have a child in her old age, and she who was said to be unable to conceive is in her sixth month. 37 For no word from God will ever fail.”
Since Brigham Young says Jesus Christ was not begotten by the Holy Ghost and Orson Pratt says Jesus required a mother and a father, does that mean the Virgin Birth spoken about in the Bible is refuted from an LDS perspective?
