Hi all! Me (25F) and my husband (26M) have recently gotten back the results of his SA. His SA was according to the Kruger Strict Criteria, and the urologist we went to said all his other numbers were in the normal range, but his morphology was at a 2%. The urologist also confirmed my husband has a vericocele in his left testicle.

All this to say- the doctor acted totally cool with these results. He said that at some point my husband may want to get surgery but didn’t recommend it now and basically told us to just keep trying for x amount of time. Part of me felt like he was just being so casual since we are on the “younger” side of things. He even stated that since I have another 10 solid years of good reproductive age that he wasn’t worried. Which really irritated me. I have been trying to research morphology and vericoceles and everything seems so unclear. In your opinion, should we advocate for vericocele surgery sooner? Is 2% morphology a concern? Has anyone had any luck with morphology improvement issuing certain supplements?

I certainly want to be proactive, but I don’t know what the right choice is to make. I’m hoping I can get some advice here. So far everything I’ve read online makes low morphology/ vericoceles either seem like no big deal, or it makes it seem like a huge deal. I would just like to hear other peoples thoughts.

Thank you all.

Three months ago, I made a thread here asking for assistance on how to increase my husband’s motility and morphology. His first sperm analysis results were as follows:

Total Motile Count: 56 million

Motility: 17%

Morphology: 0%

We took the advice here to get him on a vitamin regime (NAC, CoQ10, Fish Oil, Zinc, L-Carnitine, Vitamin D, Men’s Multivitamin) and daily 30 minute icings for three months. Yesterday, we got the results of his second SA:

Total Motile Count: 254 million

Motility: 70%

Progressive Motility: 68%

Morphology: 1%

It’s such a huge improvement!! But his morphology is still below average. My RE seems to think his results are okay for now, but should we be concerned regardless? Are there any vitamins specifically for increasing morphology?

Just wrote all this up for the Conlang Mailing List; figured I might as well post it here as well.

Templatic morphology, of a sort best known from Semitic, is minorly relevant in my conlang Mirja. Mirja mostly has normal concatenative morphology (alongside a host of phonological processes that screw with the resulting sequence of phonemes), but it has one template-based morphological process (or possibly two if I decide to go along with my idea for another one): plurality is indicated by making sure the last two syllables of a word follow a (C)VVCV pattern:

nali 'person' > naali 'people (in general)'
rhakama 'leader' > rhakaama 'leaders (in general)'

(This is usually a kind of collective plural rather than a true more-than-one plural, except with pronouns.)

This pattern doesn't get realised until after the addition of any other morphology:

naliri 'person-OBL' > naliiri 'person\PL-OBL'
rhakamara 'leader-OBL' > rhakamaara 'leader\PL-OBL'

It will end up overriding skeletal positions that are incompatible with the pattern, even if they're part of the root; and roots that already fit the pattern remain unchanged:

anna 'friend' > aana 'friends'
maali 'cat'~'cats'

So what happens to words that are only one syllable, and don't have enough material to fill the template in the first place? It seems like you just copy and paste:

ma '2sg' > maama '2pl'
no '1sg' > noono '1pl'

However, it turns out there's no copying involved whatsoever: you've just replaced the shape of the word, but not the underlying segments. From an autosegmental perspective, you still only have the segments /ma/ or /no/, they're just associated to a CVVCV skeleton - with the result that e.g. one /m/ is multiply associated to two C positions. In a lot of languages, there's no non-theoretical motivation for this analysis versus the copy-paste analysis, but in Mirja there is - because there's a morpheme that's just a floating feature bundle* that docks to the last consonant of a word and turns it into a voiceless fricative:

ma '2sg' > mha [ɸa] '2sg\TOP'
no '1sg' > nho [θɔ] '1sg\TOP'

When this attaches to a one-syllable root word that's been extended to fit the CVVCV plural template, both of the 'copies' of the consonant are altered:

maama '2pl' > mhaamha [ɸaaɸa] '2pl\TOP'
noono '1pl' > nhoonho [θɔɔθɔ] '1pl\TOP'

From a theoretical perspective, there's only one cons

I'm 27, my husband is 29. TTC for about 18 months. We're both overall healthy. My tests have all come back normal, my husbands morphology came back at 1%. He doesnt smoke or drink, doesnt even drink coffee. We eat pretty healthy and walk a lot. He's been taking a mens multivitamin , coq-10 , l-carnitine & alpha liporic acid since the 1st SA results. He retested after a few months on the supplements and was still 1% Has anyone had a similar situation?? Were you able to concieve naturally? How long did it take ? Or did you need iui or ivf? Any info is really appreciated 💕

The 5-HT2A serotonin receptor is the most abundant serotonin receptor subtype in the cortex and is predominantly expressed in pyramidal neurons. The 5-HT2A receptor is a target of several hallucinogens, antipsychotics, anxiolytics, and antidepressants, and it has been associated with several psychiatric disorders, conditions that are also associated with aberrations in dendritic spine morphogenesis. However, the role of 5-HT2A receptors in regulating dendritic spine morphogenesis in cortical neurons is unknown.

Here we show that the 5-HT2A receptor is present in a subset of spines, in addition to dendritic shafts. It colocalizes with PSD-95 and with multiple PDZ protein-1 (MUPP1) in a subset of dendritic spines of rat cortical pyramidal neurons.

MUPP1 is enriched in postsynaptic density (PSD) fractions, is targeted to spines in pyramidal neurons, and enhances the localization of 5-HT2A receptors to the cell periphery. 5-HT2A receptor activation by the 5-HT2 receptor agonist DOI induced a transient increase in dendritic spine size, as well as phosphorylation of p21-activated kinase (PAK) in cultured cortical neurons. PAK is a downstream target of the neuronal Rac guanine nucleotide exchange factor (RacGEF) kalirin-7 that is important for spine remodeling.

Kalirin-7 regulates dendritic spine morphogenesis in neurons but its role in neuromodulator signaling has not been investigated. We show that peptide interference that prevents the localization of kalirin-7 to the postsynaptic density disrupts DOI-induced PAK phosphorylation and spine morphogenesis.

These results suggest a potential role for serotonin signaling in modulating spine morphology and kalirin-7's function at cortical synapses.

I'm a beginner at conlanging and I decided to try to work out the morphology of my conlang. Essentially, I'm looking to see if this is "good."

Morphology

• Verbs
  • Tense
    • Not distinguished in present-tense verb usage
    • Distinguished by suffixes and are “attached” by a hyphen (written after the verb with a hyphen between)
    • Tenses: General past, distant past, recent past, present, near future, distant future, general future
    • Tense-distinguishing suffixes only have meaning when connected to verbs
  • Mood
    • Distinguished in verb conjugations
    • Moods: Imperative, indicative
    • Other moods are distinguished by modal auxiliary verbs that preface the main verb. These include; Subjunctive, conditional, hortative
  • Aspect is not distinguished
  • Voice
    • Voice is distinguished by word order
    • Only really uses one voice
  • Person and Number
    • Person and number are distinguished by verb conjugation
    • Agrees with the subject of the sentence
  • Evidentiality is not distinguished
• Nouns
  • Case
    • Same as English; mostly gone, but still evident in pronouns
    • Cases primarily used: Nominative, accusative/oblique, genitive/possessive
  • “Gender”
    • Originally used 3 classifications: human, non-human, inanimate
    • Exposed to different cultures, forced concepts of male and female
    • Eventually added a neutral classification
    • Modern-usage of “gender” classification: masculine human, neutral human, feminine human, non-human, inanimate
  • Number is only distinguished in pronouns (+ verb conjugation)
  • Person
    • Only distinguished in pronouns (+ verb conjugation)
    • Uses 3 types of “person”: 1st, 2nd, 3rd

Syntax

• SVO word order
• Modifiers
  • Auxiliary words tend to come before the word they modify
  • Adjectives / adverbs come after the word they modify
• Ex. “If I had known, I could have easily helped you yesterday.”
  • If it were written in my conlang, it would have a sentence structure that would read similar to;
    • Yesterday + I + hypothetical past-tense + know, 1st person singular + I + factual implication + help, 1st person singular + -recent past + easy + you

I particularly like morphology and the use of botanical descriptions such as leaf shapes and margins.

Gearing up for our second IVF cycle, I decided to implement a few things to help my husbands severe OAT diagnosis. He is a 31 year old, very fit and healthy fella. We had a TESE biopsy done in December which showed 50% of the sample had normal spermatogensis, 20% hypospermatogenesis, 20% maturation arrest, and 10% Sertoli cell only. Normal hormone profile, karyotype and no microdetions. After some research and consulting with specialists, I decided to try a few new things:

For reference: His counts have remained relatively steady at .3-.5mil/mL, 0% morph, and 20-30% motility with conventional 2-4 day abstinence windows. His DNA frag was 29% with a 2 day hold.

In January we started this regimen: -No alcohol, except an occasional one glass of red wine once every 2 weeks -Conception XR (MV from theralogix) -400 mg of ubiquinol (coq10) Quinol brand -fish oil -4000 iu Vit D -probiotics -300mg r-alpha lipoic acid -1g extra L carnitine 3x a week

We just did a SA with a 12 hour hold and got these numbers: .45mil/ml 47% motility 4% normal forms Which now classifies him as severe oligospermia.

My doc was so excited! She said whatever we did worked to improve the results!

We have our ER on may 10th, so I’ll share the results when we get them. Hoping for a better outcome, and hoping this helps someone! I think the ticket is the short abstinence window, and cutting out alcohol!

*edited: 12 hr count was actually ~500,000

My wife did her iui last week and her doctor took a look under the microscope of my sample and she said it looked great! I credit tongkat 10%, zinc, fenugreek, selenium, and ashwaganda. My last analysis my morphology rating was 1. I haven’t had another done but the fact her doctor said it looked great is very promising! Wish us luck! We’ve been trying for 2 years.
