Fertilization is the process by which a sperm combines with an oocyte, or egg cell, to produce a fertilized zygote. The sperm released during ejaculation must first swim through the vagina and uterus and into the fallopian tubes where they may find an oocyte. After encountering the oocyte, sperm next have to penetrate the outer corona radiata and zona pellucida layers of the oocyte. Sperm contain enzymes in the acrosome region of the head that allow them to penetrate these layers. After penetrating the interior of the oocyte, the nuclei of these haploid cells fuse to form a diploid cell known as a zygote. The zygote cell begins cell division to form an embryo.

I have always been the skinny guy in the crowd, but when I hit 21 I decided that was going to change. I started with a strict diet and lifting regimen, but it’s been slow going. I really began to suspect that low T was the culprit. At the advice of a friend, I replaced my herbal supplements with Prime Male. Since then, I have been putting on muscle faster. I have gone from a skinny guy to someone who can’t find a t-shirt that will fit my arms thanks to this little boost to my lifting. I finally feel like I am achieving the bulk and definition that I have wanted my whole life. – Zack T., Colorado, US
