A doctor specialising in assisted conception, would have advised you to bank some sperm for treatment and explained the implications and conditions regarding storage.
You will be requested to complete a consent form after due consideration of the implications.
The consent form is completed on the understanding that the terms of consent can be changed or varied at any time in accordance with the law of the land and the NHS regulations.
Written consent is also required to enable the unit to contact the referring clinician should this be necessary in the future.
Contact with persons not covered by a HFEA treatment licence is normally prohibited under the terms of the HFEA Act unless the patient has given written consent specifying the persons who can be contacted.
It will however be important to understand that NHS funding may not be available when the samples are to be put to use and that you may have to self fund your treatment such as in-vitro fertilisation of eggs, intra-cytoplasmic sperm injection, embryo replacement and other related procedures which may be required.
