In a breakthrough revelation, scientists have used specialized computer software to track the development of the early days of twin development. It is the first time that such early stage of twin development has been documented by scientists who now proposed a new theory this week that identical twins are formed as embryos.

Dr. Dianna Payne, a visiting research fellow at the Mio Fertility Clinic in Japan, and colleagues took photos every two minutes of 33 embryos growing in a laboratory. The research found that identical twins are formed after an embryo essentially collapses, splitting the progenitor cells

German scientists have achieved a breakthrough in the field of fertility treatment by using human bone marrow to create early-stage sperm cells.

The research, which was published in the academic journal Reproduction on Friday, reported that scientists were able to create spermatagonial cells, but were unable to get the cells to develop into fully functional sperm. They warned that it could take more time before they are used in fertility treatment

Pregnant women who eat a lot of beef (seven or more times per week) may be giving birth to boys with low sperm counts, according to a recent study published in the March issue of "Human Reproduction."

The study researchers can not pinpoint the exact reasons for their results, but they do believe it may have something to do with hormones, pesticides or other chemicals that are in the beef. They speculate that these byproducts may be affecting the testes of the developing fetus within the mother's womb

New research has revealed that an obese or overweight couple faces a tougher time to conceive a baby than a couple at normal weight, since the presence of fat can lead to infertility.

Obesity can also increase sub-fecundity or sub-fertility, which is the inability to conceive a child in 12 months

New research suggests that a diet high in low-fat dairy products may result in infertility. Doctors said women trying to get pregnant may want to consider switching to full-fat dairy.

Harvard University researchers studied the lifestyles of 116,000 US nurses. They were asked what kind of dairy products they consume and if they were trying and failing to conceive
