From ABC Online:

Fertility clinics in South Australia say they are struggling to keep up with an increasing demand for donor sperm.

They said rising infertility rates along with a greater number of same-sex couples and single women requesting treatments have contributed to the shortage in donated sperm supplies.

Repromed Fertility Specialists general manager Dr Hamish Hamilton said more sperm donors are needed, but numbers had been steadily declining over the past decade.

"Back in the 80s and 90s sperm donors could donate anonymously and the screening processes weren't as tight as they are now," he said.

Under legislation, those conceived through a donor are entitled to know the identity of their biological parents.

"Every sperm donor now has to agree to be contacted in 18 years time when the child reaches 18 years of age," he said.

"So that rigour around the recruitment of donor sperms means there are less donors willing to donate."

Dr Hamilton said the increase in demand at Repromed could also be attributed to a greater number of women looking to start a family later in life.
