Our Guide to Sperm Donation

November 11, 2021 2:58 pm

Sperm donation is when a man donates his semen to help either a couple or an individual conceive a baby. This donated sperm can either be introduced into a woman’s uterus, which is known as Intrauterine Insemination, or it can be used to fertilise an egg in a lab, known as In Vitro Fertilisation (IVF). We have put together this helpful guide to provide you with more information about what’s involved with sperm donation, and why it might be an option for you. Why Should I Use a Sperm Donor? There are lots of reasons why our patients may require a sperm donor in order to conceive. You may be a single woman, in a same-sex relationship, or your male... View Article

When is the Best Time to Produce a Sperm Sample?

August 27, 2018 12:07 pm

According to research carried out on sperm samples at the University Hospital of Zurich in Switzerland, the time of day and year the sperm was produced affects the quality of the sample. The study analysed 12,245 semen samples from over 7000 men, between 1994 and 2015, and considered factors such as sperm concentration, progressive motility, sperm shape and total sperm count. It is important to note that the causes of the following discrepancies are not certain, particularly as there was limited data on the late evening when sexual activity tends to be at its highest. Samples collected between the hours of 5am and 7.30am were found to display a statistically higher sperm concentration, total sperm count and a greater percentage... View Article

Sperm Tail Discovery Could Improve Fertility Treatments

April 3, 2018 10:09 am

Despite all of the research into fertility and reproduction, surprisingly little is known about the individual cell structures involved. The latest research into this area could lead to improvements in fertility treatments and their success rates. The latest discovery relates to sperm cells and their structure. A new imaging technique called cryogenic electric tomography (cryo-ET for short) allows researchers to see cells in 3D – this gives them unprecedented insight into how cells move and interact with each other. This additional dimension allowed researchers to see a new helix structure at the tip of the sperm cell’s tail, which had never been seen before. The study has been published in Scientific Reports, and could provide insights into why some sperm... View Article

Older Fathers Pass on More Gene Mutations Than Mothers

October 31, 2017 1:13 pm

A study that investigated the genomes of thousands of Icelandic parents and children has concluded that older fathers pass on far more genetic mutations to children than mothers do. Researchers found that children inherit 4 times more mutations from their fathers than their mothers, and therefore suggests that rare childhood diseases are more often caused by men’s DNA. This is not to be confused with the genetic mutations that cause infertility, which are the most significant age-related factors affecting couples and are highly correlated with the female parent’s age. Men pass on more mutations as they make sperm throughout their lifetime, and are therefore exposed to the possibility of these genetic mutations, unlike women who are born with all of...

Male Fertility in Crisis: Western Men’s Sperm Count Falls by 52%

August 21, 2017 9:11 am

Many fertility tests and treatments focus on the female partner, but a recent study has shown that male fertility in the west is in a state of crisis. A meta-analysis of sperm counts in men across a number of western countries, including North America, Australia, New Zealand, and Europe showed a decline of over 50% over the last 40 years. A study in Human Reproduction Update shows not only that the decline is substantial, but that it is showing no signs of levelling off. While numerous studies have shown a drop in sperm count across general populations this is a significant meta-analysis of the subject, which included 7,500 other studies. It is more respected because it addressed two of the... View Article

How to Choose a Sperm Donor

July 23, 2014 8:25 am

About 1,700 UK births each year are thanks to donor treatments. Women may choose to use donor sperm for a variety of reasons, perhaps they are not currently in a relationship and would like to conceive, or they may be in a same-sex relationship, or in a relationship with a man who has poor quality sperm. Each situation can have an impact on how they choose a sperm donor and how the criteria is decided. Modelling on a Partner Couples opting for sperm donation often choose to model their donor on their own characteristics to ensure that the child looks like them, or has particular attributes. Choosing a donor with similar facial features and colouring is often important to couples... View Article
