How much of the unique methylation patterns from parental gametes are conserved in the embryo after demethylation?

Parental gametes have unique methylation patterns. Early on in embryonic development, there is a demethylation cascade that largely resets the methylome. Obviously imprinted, sex-dependent methylations are predictably reestablished in the embryo, but Iโ€™m curious how much of the unique, non-imprinted methylation patterns from the parental methylomes make it through to the embryo.

Just in case: The rhino Cryovault holds repositories of rhino DNA, gametes, and tissues preserved indefinitely - in case we fail to save our rhino.

The rhino Cryovault is a biobank that holds the largest genetic repositories of rhino DNA, gametes, and tissues in the world; frozen and preserved indefinitely.ย What does it mean to save a species? What happens if, in the absolute worst-case scenario, we fail? While Hemmersbach Rhino Force is doing everything in their power to make sure that does not happen, they do have one last ace โ€“ the rhino Cryovault.

GP refused to do my blood test and give me a referral for gamete Storage. What now?

Currently in the process of beginning my transition with GenderGP while I wait to actually get somewhere on the NHS waiting list. Requested the blood tests specified by the GenderGP doctor I spoke to, and also requested a referral for gamete storage.

They refused me for the first one saying that they "don't have the expertise for it" and that I should go through the NHS route (which I already am lol). this reasoning seems kinda sus to me but that's besides the point I guess. For gamete storage, they said I'd need to request a referral for it from GenderGP, for some reason. When I got in contact with GenderGP about it though, they linked me to their fertility consideration page, and that I could "either ask local hospitals or other local private services if they will be willing to do the blood tests" or order one of their blood test kits.

Needless to say, I'm a bit confused and lost on what to do now. What should be my next step?

(Note: I live in Wales)

Why the blatant discrimination against gamete cells for having 1n cells?

There is the common theme that gametes do not need moral consideration because of their lack of a full set of 2n, 46 chromosomes.

But Down's Syndrome people are still human and they have 47 chromosomes.

Chimera's have 92 chromosomes and they are still human.

Clearly, if you give moral consideration to DS & chimeras, it isn't number of chromosomes that determines your moral worth. Yet the idea that a zygote has 46 chromosomes seems to be enough to be considered of the same moral value.

So why, then, are you (rightfully & as you should) giving moral consideration to DS and chimeras?
Why, then, are you not giving moral consideration to gametes?

It seems as if there is something else going into this moral consideration.

Familial gamete donation?

Hello. So, I am a woman in my early 20s dealing with infertility due to a genetic condition. Specifically, I have primary ovarian failure, which means that I have no eggs in my ovaries. I have been considering familial gamete donation with eggs possibly donated from one of my two sisters (this would be way in the future btw). I was just wondering if any adoptees could provide their perspective on the ethics of this? Iโ€™ve seen that adoption tends to be viewed as a trauma due to separation from the biological parent, and I donโ€™t want to willingly inflict trauma on an infant. Is it the same with gamete donation, since you arenโ€™t the resulting childโ€™s biological parent?

A Guide to NHS Funded Fertility Preservation (Sperm/ Egg/ Gamete Storage - Cryopreservation)

My journey to accessing fertility preservation was an absolute nightmare. This is due to primarily Covid, but also funding issues. I am writing this post in the hope it greatly simplifies navigating the process for others, so they don't have to go through what I had to.

My journey began in January when I finally received my diagnosis from a specialist, went to visit my GP and asked for NHS-funded fertility preservation. My GP (like many GP's) was unsure how to do this and advised they'd investigate and get back to me. It became apparent that they forgot to do this. I saw another GP 4 weeks later, who advised the process and put in a funding application. There were unfortunately admin issues that meant I didn't receive my approved funding until another 6 weeks later. By this point it was too late, as all non-emergency/ imminently life-threatening procedures across the entire NHS were basically postponed because of Covid-19 to allow there to be more hospital beds, and minimise transmission between healthcare workers.

I got there eventually. In July I was finally advised the fertility clinic could see me. However, that same clinic went into a second lockdown meaning my treatment was postponed until late August, and I returned for a second appointment this month.

I've now finally started hormones 10 days ago - whoop! :) NHS funded fertility preservation during these strange times we find ourselves in definitely is possible. I'd definitely advise however, if when reading this post your region is about to enter another Covid lockdown, you act quickly, forget NHS funding (if possible), and find a means of self-funding to avoid going through the turmoil of waiting (and not knowing when the wait will be over.)

If however another lockdown in your region seems unlikely at the time of reading this post, then this is how you can pursue NHS funding.

I won't go into all the in's and out's. Just here's what you need to do:

  • Ask your GP surgery what specific region NHS Clinical Commissioning Group they belong to.

Tip: if you live in London you most likely belong to the North West London Consortium (Group) of CCG's. The 8 London CCG's (Brent, Harrow, Hillingdon, Central London, West London, Hammersmith & Fulham, Hounslow and Ealing) all abide by North West London Consortium of CCG's funding policies

  • Look on your specific region's NHS CCG website and find out if there is an existing funding policy in place for Cryopreservation (Gamete/ Eg

NHS funding for gamete storage

Hi everyone,

Had confimation today that my fertility/endo team will be going ahead and applying for funding on my behalf for my egg harvesting operation, I've been waiting for 2 years for this specifically so this is great news.. he sounded confident that I would be accepted, but I cant help think I need to prepare myself mentally and financially as much as I can just incase it falls through and I'm not accepted funding too.. has anyone got experience in this, and could maybe explain more how getting funding through NHS for this works, he asked what area of Birmingham I live in.. does this make a difference? A bit of background I'm 26 and trans ftm.. I have Endometriosis stage 4, undiagnosed for 10years so its quite a mess inside there (my FSH blood test was worryingly high in his opinion, but then my AMH came back ok- he's still concerned about those two results being so different) and Crohns disease (have had 4 bowel resections in past) both impact my daily life a lot and so its important I have the eggs harvested before starting HRT testosterone which should hopefully help control the Endometriosis.

Thanks in advance people I'd really appreciate any insight at all!

(TW reproductive/fertility talk) Gamete storage/egg harvesting procedure advice pls

Hi everyone,

Just wondering if anyone who has had gamete storage/egg harvesting done could explain roughly what the process is like.. I'm aware of the general procedure itself and know you have to self inject medication daily (150units gonadotropin) for 2 weeks to expand the eggs.. does that affect you in any major ways apart from the obvious? Is there visible/uncomfortable bloating/swelling? I have Endometriosis stage 4 and Crohns, so I'm expecting it will definitely be more painful than the average persons. Also emotionally did you find the medications had any influences? I'm at college atm and I'm wondering if I'll be fine to continue going there daily or of it would be best to book the 2 weeks off if theres going to be any uncomfortable times.. if anyone could shed any light I'd really appreciate it.

Thanks a lottt
